Virtualization

virtualization

Technically speaking, virtualization offers profound changes to the way data centers perform and makes sense on multiple levels.

Less heat from servers- Virtualization helps data centers have less hardware and less servers often leads to one thing- less heat generation. Generation of less heat in data centers often gets rid of host of issues and one such major thing is that it lessens cooling costs.

Reduces costs- Hardware costs the most in a data center. The moment data center managers work out a plan to reduce hardware, they will observer easier maintenance, less electricity usage and overtime this all adds up to significant cost savings.

Faster Redeployment- Generally, when a physical server dies, the redeployment time depends on a number of factors-

  • Do you have a backup server ready?
  • Do you have an image of your server?
  • Is the data on your backup server current?

With virtualization, the redeployment can occur within minutes. Virtual machines snapshots can be enabled with just a few clicks. And with virtual backup tools, redeploying images will be so fast that end users will hardly notice there was a downtime.

Easier Backups- Virtualization offers full backups and snapshots of all virtual machines. These virtual machines can be moved from one server to another and redeployed easier and faster. Snapshots can be taken throughout the day, ensuring much more up to date data is available on hand. And because redeployment of a snapshot is faster than booting up a typical server, downtime can be cut down on a dramatic note.

Green Computing- All those who are interested in embracing green computing in their enterprise environments should go for virtualization. It not only helps in reducing carbon footprint, but also helps in putting the company image on top in the industry. Also consumers want to see companies do their best in saving the planet from pollution.

Testing environments- Virtualization makes testing easier and isolates the testing environment from end users while still keeping them online. As a result, when the application is ready for deployment, users can go live with it in a much easy way.

No vendor lock-in- One of the nice things about virtualization is the abstraction between software and hardware. This means you don’t have to be tied down to one particular vendor — the virtual machines don’t really care what hardware they run on, so you’re not tied down to a single vendor, type of server (within reason of course), or even platform.

Propels the process of disaster recovery- Disaster recovery is quite a bit easier when your data center is virtualized. With up-to-date snapshots of your virtual machines, you can quickly get back up and running. And should disaster strike the data center itself, you can always move those virtual machines elsewhere (so long as you can re-create the network addressing scheme and such). Having that level of flexibility means your disaster recovery plan will be easier to enact and will have a much higher success rate.

Single minded servers- Virtualization helps in having disparate server environment on premises. Users can have a separate email server, web server and database server all functioning on a single physical server.

Migration becomes easier- With a move to virtual machines, you are that much closer to enjoying a full-blown cloud environment. You may even reach the point where you can deploy VMs to and from your data center to create a powerful cloud-based infrastructure. But beyond the actual virtual machines, the virtualized technology gets you closer to a cloud-based mindset, making the migration all the more easy.

When it comes to server virtualization software technology offerings, you might not require every bit and byte of programming they're composed of, but you'll rejoice at the components of their feature sets when you need them. 

These solutions scale from a few virtual machines that host a handful of Web sites, virtual desktops or intranet services all the way up to tens of thousands of virtual machines serving millions of Internet users. If you don't know all the virtualization software names on this list, it's time for an introduction.

WE ARE SUPPORTING THE FOLLWING TOP VIRTUALIZATION SUPPORT COMPANIES

 

1. VMware

Find a major data center anywhere in the world that doesn't use VMware, and then pat yourself on the back because you've found one of the few. VMware dominates the server virtualization market. Its domination doesn't stop with its commercial product, VMware vSphere. VMware also dominates the desktop-level virtualization market and perhaps even the free server virtualization market with its VMware Server product. VMware remains in the dominant spot due to its innovations, strategic partnerships and rock-solid products.

2. Microsoft

Microsoft came up with the only non-Linux hypervisor, Hyper-V, to compete in a tight server virtualization market that VMware currently dominates. Not easily outdone in the data center space, Microsoft offers attractive licensing for its Hyper-V product and the operating systems that live on it. 

For all Microsoft shops, Hyper-V is a viable solution that has only gotten more competitive in the virtualization space with each new Windows Server release. Microsoft has also been steadily gaining traction with enterprises looking to leverage the company's Azure cloud services as well as those interested in managing both on-premises Hyper-V services and Azure services.

3. Citrix

Citrix was once the lone wolf of application virtualization, but now it also owns the world's most-used cloud vendor software: Xen (the basis for its commercial XenServer). Amazon uses Xen for its Elastic Compute Cloud (EC2) services. So do RackspaceCarpathiaSoftLayer and 1and1 for their cloud offerings. On the corporate side, you're in good company with BechtelSAP and TESCO.

4. Red Hat

For the past 15 years, everyone has recognized Red Hat as an industry leader and open source champion. Hailed as the most successful open source company, Red Hat entered the world of virtualization in 2008 when it purchased Qumranet and with it, its own virtual solution: KVM and SPICE (Simple Protocol for Independent Computing Environment). Red Hat released the SPICE protocol as open source in December 2009. 

The company's renowned Red Hat Enterprise Virtualization (RHEV) desktop and server virtualization platform is based on the KVM hypervisor and Red Hat's Enterprise Linux (RHEL) server operating system. RHEV is based on open standards and works with Linux and Windows, as well as enterprise applications like SAP, SAS and Oracle.

5. Oracle

If Oracle's world domination of the enterprise database server market doesn't impress you, its acquisition of Sun Microsystems has made it an impressive virtualization player. Additionally, Oracle owns an operating system (Sun Solaris), multiple virtualization software solutions (Solaris Zones, LDoms and xVM) and server hardware (SPARC). What happens when you pit an unstoppable force (Oracle) against an immovable object (the Data Center)? You get the Oracle-centered Data Center.

6. Amazon

Amazon's Elastic Compute Cloud (EC2) is the industry-standard virtualization platform. Ubuntu's Cloud Server supports seamless integration with Amazon's EC2 services. EngineYard's Ruby application services leverage Amazon's cloud as well.

7. Google

When you think of Google, virtualization might not make the top of the list of things that come to mind, but its Google Apps, AppEngine and extensive Business Services list demonstrates how it has embraced cloud-oriented services. 

The company's open source Google Ganeti cluster virtual server management software tool is built on top of existing virtualization technologies like Xen or KVM and essentially serves as a wrapper around these hypervisors to help system admins set up clusters.

8. Parallels / Odin

Parallels uses its open source OpenVZ project for its commercial hosting product for Linux virtual private servers (VPS). High density and low cost are the two keywords you'll hear when experiencing a Parallels-based hosting solution. 

These are the two main reasons why the world's largest hosting companies choose Parallels. But the innovation doesn't stop at Linux-containerized virtual hosting. Parallels has also developed a containerized Windows platform to maximize the number of Windows hosts for a given amount of hardware. 

While Parallels remains best known for its desktop and application virtualization offerings, including Parallels Desktop and Server products for Mac, the company's Service Provider business has since been rebranded as of March 2015 to Odin, and its Parallels Cloud Server offering has been renamed Virtuozzo. Virtuozzo allows applications to run in lightweight, separate containers, and Odin has been working closely with both Docker and Google on container standards.


9. Huawei

Huawei is one of the newer players on the virtualization scene, having launched its enterprise business in 2011. While still relatively unknown in the U.S., Huawei has established a strong market base with telcos and in emerging markets and countries like China, Brazil, Russia and India. 

The company's FusionSphere virtualization infrastructure software headlines Huawei's virtualization and cloud infrastructure stack, and is based on Xen. As with many of the leading virtualization vendors, Huawei leverages OpenStack across its FusionSphere and FusionCloud solutions.

10. VERDE VDI

Virtual Bridges is the company that invented what's now known as virtual desktop infrastructure, or VDI. Virtual Bridges' VERDE product has allowed companies to deploy Windows and Linux Desktops from any 32-bit or 64-bit Linux server infrastructure running kernel 2.6 or above. (You can learn more about this Desktop-as-a-Managed Service by downloading the VERDE whitepaper.) 

In February 2015, NIMBOXX acquired Virtual Bridges' VERDE VDI business. NIMBOXX currently uses the VERDE VDI technology as a turnkey offering for virtual desktop workloads and also as part of its broader mission of delivering software-defined data center-in-a-box solutions to companies of all sizes.
