How To Boosts Your Business Growth With Great Web Design?

User experience and professional web design are core elements crucial to winning customers online and boosting profits. With the demands of a data-driven market economy, developing an impressive website design is instrumental in creating a more accessible user experience. The union of these two elements is essential in achieving better conversion rates and ultimately paves the way to boost your profits. Web design is way more than just looking aesthetically pleasing to your website visitors. In fact, each element that makes up your web page has a significant impact on your site visitors’ activity when they land on your page. As a webmaster, your goal is to capture the hearts of your site visitors, provide answers to their query, keep them engaged, encourage them to subscribe, and prompt them to respond to your call-to-action.

In fact, design principles became so appealing that people started to use them as guiding points for transforming organizations. This led to the emergence of business design – a discipline about applying design thinking to the organizational structure. Though this approach is all the rage now, not all companies embrace it. However, every business can make design work for their brand. Being a marketer, I saw many businesses rise and fall because of design. All those succeeding seemed to follow a few simple guidelines. I’ll list some of these trends here for you to try them out and maybe onboard them in your company.

Web Design To Boost Business Growth

Starting a web design business is an ideal opportunity. The industry is growing at a rapid rate and now’s the time to invest in creating a successful brand. However, it is a competitive industry so it’s important to carefully lay the foundation for your business so you can avoid those “Wait, what???” scenarios that too many first-time business owners face.

  • Make your site mobile responsive
    • Mobile responsiveness is critical for a website to be effective. American adults spend more than five hours on their mobile phones every day, while more than one-third do all of their shopping online via mobile device. Needless to say, your business’s mobile website must offer a positive user experience.
  • Make it easy to find
    • You need a domain name that either matches your company name or describes your business in some way. You can even have multiple domains that point to the website. This means incorporating technical SEO best practices, keyword research, content marketing and paid advertisement campaigns to drive traffic to your website.
  • Design With The Customer In Mind

    • Generally, one of the purposes of your small business website is to acquire customers. So, you have to design with them in mind.

      This manifests itself in a few ways, but two common mistakes I see are:

      1. Not speaking to customer problems
      2. Not having clear calls to action
  • Keep your design simple

    • Limit the use of fonts, colors, and GIFs, which can distract and pull the eyes away from the focus of the webpage. Short paragraphs and bullet points also make the information more scannable and likely to be read. Ian Lurie, CEO of internet marketing company Portent Inc., suggests keeping paragraphs shorter than six lines.
  • Represent Your Personality

    • Just as brick-and-mortar businesses invest heavily in their storefronts to represent their brand images, e-commerce retailers need to create high-quality online experiences in keeping with the brand perception, as Tom Lounibos, co-founder of SOASTA, told Business News Daily.
  •  Incorporate SEO best practices

    • Many, if not, all businesses today invest in SEO to improve their website rankings. With over 12 billion searches on Google alone, it really pays off to have an effective SEO strategy in place to outshine all other websites who offer the same product or service as you.
  • Make it easy to navigate

    • your top-level navigation menu to five clearly labeled tabs, with related pages organized under them. You should also offer a clear way to get back to the homepage no matter where your readers land. Very often, a Google search may take your reader to a page on your website other than the homepage.
  • Make It Easy To Share Your Content

    • Another way to enhance your web design is to make it easy to share your content Free plugins like sumome or addthis make it easy for people to share content that you’ve created, especially on your blog. This increases the probability that more people see and/or link to your content, which should factor into your design.
  • Use Clear Calls To Action

    • Each page on your website should entice the reader to do something. In other words, you need to give them a call to action. These landing pages should encourage users to take a certain action, such as to call your company, sign up for a service, buy a product, download a whitepaper, or do something else that benefits your business goals. Give them a noticeable invitation to take the action: a button, a link, or clear verbiage. Keep it above the fold if possible so that readers do not have to scroll before finding the call to action.

Conclusion

Design can boost your business growth in multiple ways. Being a key agent to transform brands, it can improve sales and production efficiency. Three global trends of design as a coherent discipline manifest in practical guidelines for building a website. By making our online presence customer-based, we create a great customer journey and lead users along the conversion path.

However, they are unlikely to take any actions on your website if your brand doesn’t have credibility and trust. This can be fixed by making your online presence authentic and principle-based. Finally, strong visuals and video enriching your design can spark innovation, straighten your brand and differentiate your product (or service).

Disk Space in Web Hosting.

What is disk space?

In a hosting, disk space is the amount of space available on the server for storing the content of your site. This content includes pages, images, videos, files, databases, among others. In some cases, it can also be used to store emails, but this is not a rule. Therefore, when you host a website, all your content is stored in that space. As you update it, new content is being stored. This is done automatically and no action is required. Disk space offered by hosting companies varies greatly, including by type of hosting. In shared hosting, this space is divided among the clients, who occupy the same server. In these cases, it can be limited by client or “unlimited”. Since more robust hosting, such as VPS and dedicated, this space is fixed and is limited to the size of the hard disk installed on the server.

Disk space is probably one of the easiest concepts in web hosting to understand, thanks to its use in our day-to-day computing lives. Simply put, disk space is the storage capacity on your computer or server that enables you to house everything from backups and software to cat videos and selfies. With search engines detecting an estimated 5.3 billion pages of websites, securing and optimizing your disk space is critically important as the internet continues to expand.

How Much Web Hosting Storage Do You Need?

Determining a web hosting package with the right amount of resources, including RAM, CPU cores, and disk space is one of the most critical decisions you need to make when taking your business online.  This disk space will store all your website’s dynamic content, files, and critical data. You can think of it as similar to the hard drive storage on your local computer machine. Unfortunately, many users overestimate or underestimate the disk space storage—impacting their purchasing decisions.  In this article, we’ll guide you to determine the right amount of disk space for your website, so you don’t end up spending more and worrying about the negative impact of less disk space for your website. Let’s first quickly understand what disk space is.

Text-based websites with little content use the least amount of storage. On the other hand, images and videos take up a lot of space. One WordPress installation, including all the plugins and directories, will usually take up to 1GB of storage. There are plenty of exceptions here, of course — these are guesstimates. So, if you’re running a blog where only you’re uploading content, and it’s just a few images and videos, then you don’t need a lot of storage. On the other hand, if your website will serve as your portfolio for your photography career, you’re going to need a lot of storage because of all the resource-rich media that you’ll be uploading.

How to evaluate the disk space of my site?

Accurately calculating the use of disk space can be a tricky task when the site does not yet exist. The good news is that most of the time, this is not necessary. An estimate is more than enough since you just need to figure out which type of hosting to hire.

As we speak, all content of the site is stored in the disk space of the hosting. In some cases, this space is also used to store emails. Before calculating the required disk space for your website, it is important to understand a few points:

  • Images, videos, and audios are often the content that occupies more space in a website;
  • Blogs and virtual stores tend to take up more disk space than institutional sites, because of a number of multimedia files;
  • Publishing images without any type of optimization can compromise the disk space of your hosting;
  • Emails can be the villain of a hosting, depending on the number of accounts and use of the email.

If you’re just getting started, these three tips will help you make a solid estimate:

  • Assess the average page size of your website:

Design a typical page and measure it to confirm the size of the files you will have on your average page. Make sure you account for pages with web apps, such as shopping carts or contact forms.

  • Determine the potential number of webpages you need:

If your website is a simple blog, you can probably count on two hands the number of pages you’ll have. For an e-commerce site, it’s also easy to measure: How many product pages will you carry? Building a site map can also help you determine how your overall website will look. From there, you can determine the number of pages required and have a pretty good estimate of the types of files that will be on each page.

  • Estimate the number of monthly visitors to your website:

Every time a webpage is viewed, changed, accessed, uploaded or downloaded from your website it affects the amount of bandwidth you need. Also take into account the number of pages they will view during a visit. It’s important to account for web hosting space for your current files and allow room for growth so you can add features as your client base or number of visitors grows.

Web Hosting Company in Nepal

Conclusion

As we have seen, disk space is used to store all of the site content. In some cases, also the email. It is an important resource of hosting and should be considered by both whom already has a website and those who are building one. To estimate the disk space required for your site, consider your site type and the amount of content it will have. Also, think about emails if you use this feature from your hosting. If you already have a hosting, be sure to keep track of your disk space usage. This information can be easily found on the dashboard of your hosting.

What Is Affiliate Marketing and How to Get Started in Nepal

What is Affiliate Marketing?

Affiliate marketing is the process of earning a commission by promoting another person’s (or company’s) product. You find a product you like, promote it to your audience, and earn a piece of the profit for each sale that you make. It’s similar to a salesperson earning a commission, except you don’t work for the company. Instead, it’s like earning a reward for sending a new customer to the company.

In other word Affiliate marketing is a type of performance-based marketing in which a business rewards one or more affiliates for each visitor or customer brought by the affiliate’s own marketing efforts. Affiliate marketing may overlap with other Internet marketing methods, including organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and display advertising.

Types of Affiliate Marketing

  • Unattached Affiliate Marketing: This is an advertising model in which the affiliate has no connection to the product or service they are promoting. They have no known related skills or expertise and do not serve as an authority on or make claims about its use.
  • Related Affiliate Marketing: As the name suggests, related affiliate marketing involves the promotion of products or services by an affiliate with some type of relationship to the offering. Generally, the connection is between the affiliate’s niche and the product or service
  • Involved Affiliate Marketing: This type of marketing establishes a deeper connection between the affiliate and the product or service they’re promoting.

How Does Affiliate Marketing Work?

There are three main players in an affiliate marketing arrangement:

  1. You and your website—the “affiliate.”
  2. The affiliate company (or network). In the simplest affiliate arrangements, you work directly with a single company to promote one or more of their products. There are more complex affiliate networks that provide an opportunity to earn affiliate revenue in Nepal  on a various range of products, such as Daraz, Sastodeal and Digitalkhani.
  3. The customer. This is a member of your audience who uses your affiliate link to purchase a product from the affiliate company or network.

A company that offers an affiliate marketing program may call it by a different name—these programs are also commonly called partner programs or referral programs.

Benefits of Affiliate Marketing

  • Affiliate marketing is easy to get started with, and costs little. Most affiliate programs are free to join, and you don’t have to create, stock, or ship products, which also means less hassle/responsibility.
  • You’re not the product owner, so you don’t lose anything if a customer doesn’t buy.
  • Affiliate marketing provides the potential for passive income.
  • More freedom. When you start earning passive income, you can work anytime and from anywhere, as long as you have internet access.

Drawbacks of Affiliate Marketing

  • It can take time to generate the amount of traffic needed to result in substantial income.
  • You don’t own or control the product/service you’re recommending, so you can’t control the quality or customer experience
  • Not all affiliate programs are created equal. While most companies that offer affiliate commissions are stable and ethical, there are shady companies out there too, some of which may not pay what they say they will.

What Is an Example of Affiliate Marketing?

Digitalkhani is a Nepal-based digital media affiliate company which was recently lunched. Affiliates and Visitors can read Vendor’s product reviews and select affiliate links to purchase and they can earn a commission from each sale generated from their website. Affiliates can also earn based on action or (PPC – Pay Per Click), e-mail marketing, content marketing.

Conclusion

Incomes for affiliate marketers vary, with some making a few hundred and some making six figures. It depends on what is being marketed, how much influence the marketer has, the affiliate’s reach, and how much time is invested in marketing products. Often, those spending more time marketing the company’s products will earn more money. Through Affiliate marketing all Vendor, Affiliate company and Audience can get benefits. In short affiliate marketing can be a win–win–win. But at the center of this is one thing: your audience’s trust.

What are Databases? Difference between Relational database and NoSQL.

What Is a Database?

A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management system (DBMS). Together, the data and the DBMS, along with the applications that are associated with them, are referred to as a database system, often shortened to just database.

Data within the most common types of databases in operation today is typically modeled in rows and columns in a series of tables to make processing and data querying efficient. The data can then be easily accessed, managed, modified, updated, controlled, and organized. Most databases use structured query language (SQL) for writing and querying data.

What is a database management system (DBMS)?

A database typically requires a comprehensive database software program known as a database management system (DBMS). A DBMS serves as an interface between the database and its end users or programs, allowing users to retrieve, update, and manage how the information is organized and optimized. A DBMS also facilitates oversight and control of databases, enabling a variety of administrative operations such as performance monitoring, tuning, and backup and recovery.

 

Some examples of popular database software or DBMSs include MySQL, Microsoft Access, Microsoft SQL Server, FileMaker Pro, Oracle Database, and dBASE.

Relational database and NoSQL.

Relational and NoSQL are two types of database systems commonly implemented in cloud-native apps. They’re built differently, store data differently, and accessed differently. In this section, we’ll look at both. Later in this chapter, we’ll look at an emerging database technology called NewSQL. Relational databases have been a prevalent technology for decades. They’re mature, proven, and widely implemented. Competing database products, tooling, and expertise abound. Relational databases provide a store of related data tables. These tables have a fixed schema, use SQL (Structured Query Language) to manage data, and support ACID guarantees.

No-SQL databases refer to high-performance, non-relational data stores. They excel in their ease-of-use, scalability, resilience, and availability characteristics. Instead of joining tables of normalized data, NoSQL stores unstructured or semi-structured data, often in key-value pairs or JSON documents. No-SQL databases typically don’t provide ACID guarantees beyond the scope of a single database partition. High volume services that require sub second response time favor NoSQL datastores.

Relational database

  • Relational database manages only structured data and Relational Database is used to handle data coming in low velocity.
  • NoSQL databases are used to handle moderate volume of data with centralized structure.
  • Relational Database follows acid properties. (Atomicity, Consistency, Isolation, and Durability)
  • Relational Database supports a powerful query language and has fix schema eg. MySQL.

NoSQL Database

  • NoSQL database can manage structured, unstructured and semi-structured data and have no single point of failure.
  • NoSQL databases can handle big data or data in a very high volume .
  • NoSQL database gives both read and write scalability and deployed in horizontal fashion
  • NoSQL Database supports a very simple query language. eg. MangoDB

Is NoSQL better than SQL?

  • NoSQL tends to be a better option for modern applications that have more complex, constantly changing data sets, requiring a flexible data model that doesn’t need to be immediately defined. Most developers or organizations that prefer NoSQL databases, are attracted to the agile features that allow them to go to market faster, make updates faster. Unlike traditional, SQL based, relational databases, NoSQL databases can store and process data in real-time.
  • While SQL databases do still have some specific use cases, NoSQL databases have many features that SQL databases are not capable of handling without tremendous costs, and critical sacrifices of speed, agility, etc.

 

 

What is KVM hypervisor?

0

KVM (Kernel-based Virtual Machine) is the leading open source virtualisation technology for Linux. It installs natively on all Linux distributions and turns underlying physical servers into hypervisors so that they can host multiple, isolated virtual machines (VMs). KVM comes with no licenses, type-1 hypervisor capabilities and a variety of performance extensions which makes it an ideal candidate for virtualisation and cloud infrastructure implementation.

History

Avi Kivity began the development of KVM in mid-2006 at Qumranet, a technology startup company that was acquired by Red Hat in 2008. KVM surfaced in October, 2006 and was merged into the Linux kernel mainline in kernel version 2.6.20, which was released on 5 February 2007. KVM is maintained by Paolo Bonzini.

KVM converts Linux into a type-1 (bare-metal) hypervisor. All hypervisors need some operating system-level components—such as a memory manager, process scheduler, input/output (I/O) stack, device drivers, security manager, a network stack, and more—to run VMs. KVM has all these components because it’s part of the Linux kernel. Every VM is implemented as a regular Linux process, scheduled by the standard Linux scheduler, with dedicated virtual hardware like a network card, graphics adapter, CPU(s), memory, and disks.

KVM provides device abstraction but no processor emulation. It exposes the /dev/kvm interface, which a user mode host can then use to:

  • Set up the guest VM’s address space. The host must also supply a firmware image (usually a custom BIOS when emulating PCs) that the guest can use to bootstrap into its main OS.
  • Feed the guest simulated I/O.
  • Map the guest’s video display back onto the system host.

Originally a forked version of QEMU was provided to launch guests and deal with hardware emulation that isn’t handled by the kernel. That support was eventually merged into the upstream project. There are now numerous Virtual Machine Monitors (VMMs) which can utilise the KVM interface including kvmtool, crosvm] and Firecracker and numerous specialised VMMs build with frameworks such as rust-vmm.

KVM is part of Linux. Linux is part of KVM. Everything Linux has, KVM has too. But there are specific features that make KVM an enterprise’s preferred hypervisor.

Security

KVM uses a combination of security-enhanced Linux (SELinux) and secure virtualization (sVirt) for enhanced VM security and isolation. SELinux establishes security boundaries around VMs. sVirt extends SELinux’s capabilities, allowing Mandatory Access Control (MAC) security to be applied to guest VMs and preventing manual labeling errors. Since KVM is part of the Linux kernel source code, it benefits from the world’s biggest open source community collaboration, rigorous development and testing process as well as continuous security patching.

Storage

KVM is able to use any storage supported by Linux, including some local disks and network-attached storage (NAS). Multipath I/O may be used to improve storage and provide redundancy. KVM also supports shared file systems so VM images may be shared by multiple hosts. Disk images support thin provisioning, allocating storage on demand rather than all up front.

Hardware support

KVM can use a wide variety of certified Linux-supported hardware platforms. Because hardware vendors regularly contribute to kernel development, the latest hardware features are often rapidly adopted in the Linux kernel.

Memory management

KVM inherits the memory management features of Linux, including non-uniform memory access and kernel same-page merging. The memory of a VM can be swapped, backed by large volumes for better performance, and shared or backed by a disk file.

Live migration

KVM supports live migration, which is the ability to move a running VM between physical hosts with no service interruption. The VM remains powered on, network connections remain active, and applications continue to run while the VM is relocated. KVM also saves a VM’s current state so it can be stored and resumed later.

Performance and scalability

KVM inherits the performance of Linux, scaling to match demand load if the number of guest machines and requests increases. KVM allows the most demanding application workloads to be virtualized and is the basis for many enterprise virtualization setups, such as datacenters and private clouds (via OpenStack®).

Scheduling and resource control

In the KVM model, a VM is a Linux process, scheduled and managed by the kernel. The Linux scheduler allows fine-grained control of the resources allocated to a Linux process and guarantees a quality of service for a particular process. In KVM, this includes the completely fair scheduler, control groups, network name spaces, and real-time extensions.

Lower latency and higher prioritization

The Linux kernel features real-time extensions that allow VM-based apps to run at lower latency with better prioritization (compared to bare metal). The kernel also divides processes that require long computing times into smaller components, which are then scheduled and processed accordingly.

Cost-efficiency

Last but not least, the cost is a driving factor for many organizations. Since KVM is open source and available as a Linux kernel module, it comes at zero cost out of the box. Businesses can optionally subscribe to various commercial programs, such as UA-I (Ubuntu Advantage for Infrastructure) to receive enterprise support for their KVM-based virtualization or cloud infrastructure.

How much RAM do you need?

0

What is RAM?

RAM (Random Access Memory) provides fast access and temporary storage for data in computers. RAM sits in-between the processor and permanent data storage, like an HDD/SSD. When a computer is turned on, the processor requests data (such as the operating system) from the HDD/SSD and loads this into RAM. RAM is thousands of times faster than even the fastest SSDs, so having more RAM capacity to hold applications and data near the processor helps make computing quick and efficient.

System RAM shouldn’t be confused with the dedicated memory used by discrete graphic cards. High-end 3D games rely on video RAM, or VRAM, to temporarily store image data, like textures. Most current-generation graphics cards use GDDR5, GDDR6, and GDDR6X.

Meanwhile, system RAM is identified with DDR3 or DDR4, with the number identifying the generation. The newer term DDR5 indicates the latest RAM generation, although compatible devices may not appear in the wild for a while. You can stay up to date on what to expect with our guide to DDR5. DDR6 is in development but not readily available.

How much RAM do you need?

Determining the specs for a new laptop (or a laptop upgrade) can be a delicate balancing act. You want to spend enough so you won’t be miserable in the future, but not so much that you don’t make use of all the hardware you get. Memory (or RAM) is the perfect example of this. Your PC uses RAM to hold data temporarily: When you’re opening applications, working on large files in Photoshop, or even juggling dozens and dozens of browser tabs, that data is being stored in the system memory, not on your SSD or HDD. The more memory-intensive tasks you do, the more RAM you should have. It’ll keep your computer feeling fast and responsive.

Many laptop shoppers know this, but not exactly how much to get. So we’ve broken down what to expect from common RAM configurations, plus some tips at the end for purchase strategies.

  • 4GB: Low-end Chromebooks and some tablets come with 4GB of RAM, but it’s only worth considering if you’re on an extreme budget.
  • 8GB: Typically installed in entry-level notebooks. This is fine for basic Windows gaming at lower settings, but rapidly runs out of steam.
  • 16GB: Excellent for Windows and MacOS systems and also good for gaming, especially if it is fast RAM.
  • 32GB: This is the sweet spot for professionals. Gamers can enjoy a small performance improvement in some demanding games, too.
  • 64GB and more: For enthusiasts and purpose-built workstations only. Engineers, professional A/V editors, and similar types need to start here and go higher if needed.
These recommendations are valid for the following Operating Systems:

Windows 10/Windows 8/8.1: 1GB (32-bit) or 2 GB (64-bit) to 128GB (Win8)–512GB (Win8 Professional and Enterprise)

  • Windows 7: 1GB (32-bit) or 2 GB  to 192GB max (64-bit).
  • Windows Vista®: 1GB (32-bit) or 2 GB to 128GB (64-bit)
  • OS X 10.10 Yosemite: 2GB+
  • OS X 10.9 Mavericks: 2GB+
  • Linux: 1GB (32-bit) or 2 GB (64-bit)

Laptop upgrades

For older laptops capable of RAM upgrades, first determine how much RAM is already in your system. If the amount matches your use case (as described above), consider a different upgrade instead—for example, if your system has a hard disk drive instead of an SSD, change that out first before adding more RAM.

If you think you can benefit from more RAM, verify first what SODIMMs are already installed. Is it a single stick? You can buy a second one with matching specs and pop it in for both a capacity bump and a faster dual-channel configuration. If both slots are already populated, you should then buy a larger capacity set to replace both sticks. Follow our guide on upgrading RAM to make this process plus installation a breeze.

Scalability In Computing And It’s Type

0

Scalability

Scalability is the property of a system to handle a growing amount of work by adding resources to the system. In computing, scalability is a characteristic of computers, networks, algorithms, networking protocols, programs and applications. An example is a search engine, which must support increasing numbers of users, and the number of topics it indexes. Webscale is a computer architectural approach that brings the capabilities of large-scale cloud computing companies into enterprise data centers.

Types of Scalability

Horizontal (scale out) and vertical scaling (scale up)

Resources fall into two broad categories: horizontal and vertical.

Horizontal or scale out

Scaling horizontally (out/in) means adding more nodes to (or removing nodes from) a system, such as adding a new computer to a distributed software application. An example might involve scaling out from one web server to three. High-performance computing applications, such as seismic analysis and biotechnology, scale workloads horizontally to support tasks that once would have required expensive supercomputers. Other workloads, such as large social networks, exceed the capacity of the largest supercomputer and can only be handled by scalable systems. Exploiting this scalability requires software for efficient resource management and maintenance.

Vertical or scale up

Scaling vertically (up/down) means adding resources to (or removing resources from) a single node, typically involving the addition of CPUs, memory or storage to a single computer. Larger numbers of elements increases management complexity, more sophisticated programming to allocate tasks among resources and handle issues such as throughput and latency across nodes, while some applications do not scale horizontally.

scale up vs scale out

The advantage of scale-up system is that no data copying is needed. In general, many applications can run faster on scale-up systems because all data are located directly in-memory and available to all processors. In addition, applications can use extra memory without the need to distribute data across multiple systems. Perhaps the biggest advantage of scale-up systems is that the decision to add extra resources (memory or processors) to an application is always optional not required. In addition, there is no need to expand to multiple machines for extra memory or processors. Finally, scale-up systems are easily upgradable with little or no impact on users.

As compared to scale-out systems, scale-up systems have limits on scalability. (i.e. the number of processors and total memory size is much lower than can be achieved with scale-out systems). It should be noted that these limits are normally quite large and do not represent an issue for many applications. Scale-up systems do present a single point of failure, however they are usually well engineered and designed with redundant features to reduce the impact of any hardware issues. Finally, because memory is shared, there can be cases where locked portions of memory may cause processors to stall while waiting for access.

 

 

 

Hypervisor And It’s Type Hypervisor In Cloud Computing

0

Hypervisor

A hypervisor (or virtual machine monitor, VMM, virtualizer) is similar to an emulator; it is computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system–level virtualization, where all instances (usually called containers) must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the same kernel.

Benefits of hypervisors

There are several benefits to using a hypervisor that hosts multiple virtual machines:
  • Speed: Hypervisors allow virtual machines to be created instantly, unlike bare-metal servers. This makes it easier to provision resources as needed for dynamic workloads.
  • Efficiency: Hypervisors that run several virtual machines on one physical machine’s resources also allow for more efficient utilization of one physical server. It is more cost- and energy-efficient to run several virtual machines on one physical machine than to run multiple underutilized physical machines for the same task.
  • Flexibility: Bare-metal hypervisors allow operating systems and their associated applications to run on a variety of hardware types because the hypervisor separates the OS from the underlying hardware, so the software no longer relies on specific hardware devices or drivers.
  • Portability: Hypervisors allow multiple operating systems to reside on the same physical server (host machine). Because the virtual machines that the hypervisor runs are independent from the physical machine, they are portable. IT teams can shift workloads and allocate networking, memory, storage and processing resources across multiple servers as needed, moving from machine to machine or platform to platform. When an application needs more processing power, the virtualization software allows it to seamlessly access additional machines.

There are two types of hypervisors:

  • Type I hypervisor: hypervisors run directly on the system hardware – A “bare metal” embedded hypervisor,
  • Type II hypervisor: hypervisors run on a host operating system that provides virtualization services, such as I/O device support and memory management

Type II hypervisor

1. VMware Workstation/Fusion/Player

VMware Player is a free virtualization hypervisor.

It is intended to run only one virtual machine (VM) and does not allow creating VMs.
VMware Workstation is a more robust hypervisor with some advanced features, such as record-and-replay and VM snapshot support.

VMware Workstation has three major use cases:

  • for running multiple different operating systems or versions of one OS on one desktop,
  • for developers that need sandbox environments and snapshots, or
  • for labs and demonstration purposes.

2. VMware Server

VMware Server is a free, hosted virtualization hypervisor that’s very similar to the VMware Workstation.
VMware has halted development on Server since 2009

3. Microsoft Virtual PC

This is the latest Microsoft’s version of this hypervisor technology, Windows Virtual PC and runs only on Windows 7 and supports only Windows operating systems running on it.

4. Oracle VM VirtualBox

VirtualBox hypervisor technology provides reasonable performance and features if you want to virtualize on a budget. Despite being a free, hosted product with a very small footprint, VirtualBox shares many features with VMware vSphere and Microsoft Hyper-V.

5. Red Hat Enterprise Virtualization

Red Hat’s Kernel-based Virtual Machine (KVM) has qualities of both a hosted and a bare-metal virtualization hypervisor. It can turn the Linux kernel itself into a hypervisor so the VMs have direct access to the physical hardware.

KVM This is a virtualization infrastructure for the Linux kernel. It supports native virtualization on processors with hardware virtualization extensions.

Type 1 hypervisors:

1. VMware ESX and ESXi

These hypervisors offer advanced features and scalability, but require licensing, so the costs are higher.

There are some lower-cost bundles that VMware offers and they can make hypervisor technology more affordable for small infrastructures.

VMware is the leader in the Type-1 hypervisors. Their vSphere/ESXi product is available in a free edition and 5 commercial editions.

2. Microsoft Hyper-V

The Microsoft hypervisor, Hyper-V doesn’t offer many of the advanced features that VMware’s products provide.
However,  with XenServer and vSphere, Hyper-V is one of the top 3 Type-1 hypervisors.

It was first released with Windows Server, but now Hyper-V has been greatly enhanced with Windows Server 2012 Hyper-V. Hyper-V is available in both a free edition (with no GUI and no virtualization rights) and 4 commercial editions – Foundations (OEM only), Essentials, Standard, and Datacenter. Hyper-V

3. Citrix XenServer

It began as an open source project.
The core hypervisor technology is free, but like VMware’s free ESXi, it has almost no advanced features.
Xen is a type-1 bare-metal hypervisor. Just as Red Hat Enterprise Virtualization uses KVM, Citrix uses Xen in the commercial XenServer.

Today, the Xen open source projects and community are at Xen.org. Today, XenServer is a commercial type-1 hypervisor solution from Citrix, offered in 4 editions. Confusingly, Citrix has also branded their other proprietary solutions like XenApp and XenDesktop with the Xen name.

4. Oracle VM

The Oracle hypervisor is based on the open source Xen.
However, if you need hypervisor support and product updates, it will cost you.
Oracle VM lacks many of the advanced features found in other bare-metal virtualization hypervisors.

5. KVM

The open-source KVM (or Kernel-Based Virtual Machine) is a Linux-based type-1 hypervisor that can be added to most Linux operating systems including Ubuntu, Debian, SUSE, and Red Hat Enterprise Linux, but also Solaris, and Windows.

6. LXC (Linux containers)

LXC (also known as Linux containers) is a virtualization technology that works at the operating system level. This is different from hardware virtualization, the approach used by other hypervisors such as KVM, Xen, and VMware. LXC (as currently implemented using libvirt in the Compute service) is not a secure virtualization technology for multi-tenant environments (specifically, containers may affect resource quotas for other containers hosted on the same machine). Additional containment technologies, such as AppArmor, may be used to provide better isolation between containers, although this is not the case by default. For all these reasons, the choice of this virtualization technology is not recommended in production.

Conclusion

A type I hypervisor operates directly on the host’s hardware to monitor hardware and guest virtual machines, and it’s referred to as the bare metal. Usually, they don’t require the installation of software ahead of time. Instead, you can install right onto the hardware. This type of hypervisor tends to be powerful and requires a great deal of expertise to function it well. In addition, Type I hypervisor are more complex and have certain hardware requirements to run adequately. Due to this, it is mostly chosen by IT operations and data center computing. Examples of type I hypervisors include Xen, Oracle VM Server for SPARC, Oracle VM Server for x86, Microsoft Hyper-V and VMware’s ESX/ESXi. Whereas Type II also called a hosted hypervisor because it is usually installed onto an existing operating system. They are not much capable to run more complex virtual tasks. People use it for basic development, testing, and emulation. If there is any security flaw found inside the host OS, it can potentially compromise all of virtual machines running. This is why type II hypervisors cannot be used for data center computing. They are designed for end-user systems where security is a lesser concern. For instance, developers could use type II Hypervisor to launch virtual machines in order to test software product before their release. A few examples are Virtual box, VMware workstation, fusion.

 

 

Dedicated SSD Servers: Host on the Beast!

0

The field of technology is ever-changing with new inventions and products being released for the ease of consumers. When it comes to the data storage industry, we have seen the transition from magnetic tapes to solid-state storage. For Desktop, Laptops and Servers particularly, there has been an increased shift from HDD (Hard Disk Drive) to SSD (Solid State Drive).

What is Solid State Drive (SSD)?

SSD stands for Solid State Drive. This storage device uses flash memory to store data. ‘For the ease of understanding, you can think of USB flash drives. Unlike HDD, in Solid State Drive you have no moving parts, thus your disk doesn’t heat up, it consumes less energy and is able to read and write data at a faster speed.

Why Choose Dedicated SSD Servers for your Business?

1. Powerful Configuration for High-performance: With our high-performance servers, you can easily host any resource-intensive website or application! To accommodate numerous processes, critical applications and high website traffic, our Dedicated SSD Servers come with powerful SSD storage, the latest Intel Xeon D 2141 I processor along with up to 64 GB DDR4 high memory servers.

2. SSD Storage for Increased Efficiency: With SSD storage, you have the advantage of increased efficiency and a tremendous performance boost.

3. Root access for complete control: With our Dedicated SSD Hosting, you get full root access of your server. With the help of the integrated Server Administration Panel, you can customize your server environment to suit your website needs. You can Rebuild, access Web-based VNC, Restart, Shutdown and Monitor resources easily.

4. Choice of Hosting Panels: With Dedicated SSD, you can choose to administer all your websites with either of the two best hosting panels – cPanel or Plesk.

Along with this, our SSD Dedicated Servers come with:

  • Integrated Server Administration panel
  • High Memory Servers (up to 64 GB DDR4)
  • Easy cPanel and Plesk installation
  • cPanel with WHM Control Panel
  • Secured Server with IPTables Firewall
  • Unlimited POP3 Email Accounts with SMTP

Pros and Cons of SSD

Pros of SSD:

  • Speed: As SSD uses flash memory, and fewer moving parts the speed at which your device works or website loads is much faster.
  • Reliable: Less moving parts is directly proportional to less breakage or wear out of the SSD. Thus, SSD’s are more efficient when it comes to saving energy and are more environmentally friendly.

Cons of SSD:

  • Costly: Being a fairly new technology as compared to HDD, SSD is expensive even though they deliver exceptional performance.
  • Storage: Storage capacity here is again linked to the cost. Unlike HDD, SSD’s are expensive and so getting the same amount of storage capacity as that in HDD can cost you a bit more than you might have expected.

History & Evolution of Cloud Computing

0

This innovative technology’s discovery goes back to 1960’s and the evolution of cloud computing has seen multiple stages. We have come so far, and its equally important to know about how and when did cloud computing start empowering enterprises along with the entire history of cloud computing, before we dive into top trends in the future.

We have seen it, heard it, and done it. But, do we know what it is? We have been using cloud computing unknowingly through Gmail and Google docs, yet we never thought that these were cloud computing services.

What is Cloud Computing technology?

Cloud computing is a technology that puts your entire computing infrastructure in both hardware and software applications online. It uses the internet, remote central servers to maintain data & applications. Gmail, Yahoo mail, Facebook, Hotmail, Orkut, etc are all the most basic and widely used examples of cloud computing. One does not need his own PC or laptop to check some stored mail/data/photos in the mailbox but any computer with an internet connection since the data is stored with the mail service provider on a remote cloud. The technology, in essence, is a geographical shift in the location of our data from personal computers to a centralized server or ‘cloud’. Typically, cloud services charge its customers on a usage basis. Hence it is also called Software as a Service (SaaS). It aims to provide infrastructure and resources online in order to serve its clients; Dynamism, Abstraction and Resource Sharing.

The term “cloud” was actually derived from telephony. The telecommunication companies offered Virtual Private Network with good quality at affordable prices. The symbol of the cloud represented the demarcation point which was the sole responsibility of the provider. Cloud computing manages servers and network infrastructure management.

History of Cloud Computing

Let’s have a quick walkthrough of cloud computing history and evolution all these years-

1960’s

One of the renowned names in Computer Science, John McCarthy, enabled enterprises to use expensive mainframe and introduced the whole concept of time-sharing. This turned out to be a huge contribution to the pioneering of Cloud computing concept and establishment of Internet.

1969

With the vision to interconnect the global space, J.C.R. Licklider introduced the concepts of “Galactic Network” and “Intergalactic Computer Network” and also developed Advanced Research Projects Agency Network- ARPANET.

1970 

By this era, it was possible to run multiple Operating Systems in isolated environment.

1997   

Prof. Ramnath Chellappa introduced the concept of “Cloud Computing” in Dallas.

1999 

Salesforce.com started the whole concept of enterprise applications through the medium of simple websites. Along with that, the services firm also covered the way to help experts deliver applications via the Internet.

2003 

The Virtual Machine Monitor (VMM), that allows running of multiple virtual guest operating systems on single device, paved way ahead for other huge inventions.

2006 

Amazon also started expanding in cloud services. From EC2 to Simple Storage Service S3, they introduced pay-as-you-go model, which has become a standard practice even today.

2013 

With IaaS, (Infrastructure-as-a-Service), the Worldwide Public Cloud Services Market was totalled at £78bn, which turned out to be the fastest growing market services of that year.

Cloud Computing Trends – Empowering the future of Public Cloud

The estimated spending on Public Cloud Services is foreseen to surpass $500 Billion by 2023. The upcoming trends in cloud computing are going to empower industries with multiple cloud offerings and accelerated growth.  As a result, the cloud adoption will grow by 22.8% of all enterprise IT sending.  “The pandemic served as a catalyst for rapid cloud adoption and digital innovation in 2020, especially to empower remote work, collaboration and digitalization for hybrid work models”.

CONCLUSION

Cloud computing represents the next evolutionary step toward elastic IT. Cloud emergence transforms the way in which IT infrastructure is constituted and managed through consumable services for infrastructure, platform, and applications. This idea converts IT infrastructure from a “factory” into a “supply chain”. There may be a stage to come when Internet is going to be the communication channel for mass media, then we cannot imagine a world without cloud storage because keeping ownership and maintaining huge volume of data on our own infrastructure is unimaginable. So automatically cloud storage will capture the entire market as we see rental houses leased to the tenants which is an unavoidable and a must situation in a growing populated city. Cloud storage strategies and service models are still in its early stages. Standardization of service provider‟s service levels, pricing plans, data access methods, operational and security processes, emergency plans for data migration if the enterprise sooner or later wish to change vendors, improving the performance by opting better load balancing methodology are some of the thrust areas where future works on cloud storage can be focused.
