Reasons Server Virtualization is Beneficial

Virtualization of servers have been a great game-changer for use within the datacenter as well as for those who manage and administrate it. The efficiency of virtualization at times when it’s desperately needed is a great asset. However, there are only a few companies that are fully 100% virtualized. Are these companies truly taking advantage of all given benefits of virtualization, especially when they’ve virtualized quite a chunk on their servers?
Whether you use virtualization every day or if you are even new to it, be sure to acknowledge the true benefits of virtualization and not get stalled before all of those benefits become realized, for the well-sake of you and your company. Every benefit offers you the opportunity to make your life and the company more efficient and while reducing the cost of computing.

If we had to list them, what are the top 9 benefits of server virtualization? Here’s my list:

1. Consolidation of Servers

Replacing physical servers into virtual servers helps reduce costs in power and cooling by a tremendous amount. Additionally, you’ll be able to reduce the datacenter footprint which can include generator costs, UPS costs, network switch costs, rack space and floor space.

2. Halt Server Over-Provisioning

Prior to the virtualization of servers, administrators were essentially tasked with over-provisioning servers to ensure the user’s demands would be met. With server virtualization, there is no more over-provisioning and you’ll be able to perfectly size every virtual machine.

3. Saving Costs

Your company would not only save on otherwise purchased physical server hardware, power and the cooling of those servers that are consolidated, but you will also save time on administering the servers compared to when they were physical. End users will become more productive this way due to less downtime of servers.

4. Virtual Machines Moving While Running

Without a doubt, one of the amazing features of virtualizing servers is the ability to move running virtual machines from one host to another with absolutely no downtime. VMware’s vMotion can do this for you and that feature makes other features like distributed resource scheduler (DRS) and distributed power management (DPM) possible.

5. Uptime Increased

Features such as vMotion, storage vMotion (svMotion), DRS, and VMware high availability (VMHA) result in virtualized servers being up and running that much more than the same servers that were then previously running on physical servers.

6. Image-based Restore and Backup

The ability to backup and restore entire virtual machines allows you to do quickly back up the VMs and put them back, if needed. Also, image-level backups make disaster recovery that much a painless process. Even more, only incremental backups need to be performed and backups can be done in the middle of the day thanks to snapshot technology.

7. Labs Virtualized

A virtual lab is a group of virtual machines that exist on a private virtual network. The ability to create these virtual labs allows you to test vSphere, Exchange, Active Directory and much more. Prior to virtualization, this process would not have been cost effective with using physical servers.

8. Disaster Recovery Simplified

Since virtual machines are not dependent on hardware (not being tied to any particular physical server) you can easily restore image-based backups on any device that has the capability of running vSphere. Plus, software features like site recovery manager (SRM) automate the testing and failover when a disaster strikes.

9. Moving Over to the Cloud

Portability of your newly virtualized servers lets you become ready to move over to a cloud hosting company once that technology matures and you feel comfortable of moving it. Keep these benefits handy and use these benefits to give your project a jumpstart! Also note that there are many kinds of virtualization such as application, desktop, I/O, storage and more.
