The virtualization technology has brought about revolutionary changes in the world of server computing, especially in storage, applications, desktop virtualization, and cloud computing. Virtual servers have changed the way organizations set up their networks and computing environments. Virtualization technology is being adopted by businesses as it allows them to provide service offerings like SaaS, IaaS, and PaaS.
The advantages of server virtualization are extensive and compelling. Here are five of the major advantages.
- Saves Cost
The most immediate and significant benefit of server virtualization is cost savings which is due to the fewer physical servers required with virtualization. Fewer servers also mean less maintenance, saving the cost of power and cooling. Lesser used and less demanded OSes and apps can run on a single machine which also leads to saving software license costs.
- Improves Efficiency
With server virtualization, separate virtual server instances operate in place of one physical server and produce the same output in a much more effective manner. This leads to improvements through IT productivity with new servers deployed quickly. Servers not needed anymore can easily be decommissioned and taken down.
Server virtualization has inbuilt features to increase uptime, not available in physical servers. New technology/applications, recovery of data, and distribution of workloads take much lesser time. Server virtualization systems have centralized management consoles, where the status of all virtual servers can be monitored and adjusted as needed.
- Business continuity & easier disaster recovery
A very important benefit of server virtualization is the much cheaper and easier business continuity and disaster recovery it provides. If a data center is disabled due to a disaster, virtual servers can be promptly set up at a remote site to ensure continuity of business processes. Server virtualization enables cloud-based services which makes disaster recovery affordable for businesses of all sizes. Also, with the data not tied to a physical server, there is no fear of data loss in the event of data loss in one of the instances.
Server virtualization has the benefit of quick backup of entire virtual servers and restoring them. The image-based backups make it easier for disaster recovery and saves time.
- Flexibility and scalability
Virtual servers can be moved or cloned from one piece of hardware to another, making hardware upgrades and performance tuning an almost effortless process. In the same way, these capabilities enable transition to a cloud service or maintaining a hybrid infrastructure that includes on-premises and cloud resources.
In application development environments, a huge advantage is the ability to create, deploy and then to destroy virtual servers, if it was only intended for short periods of application testing.
- Improves storage capacity management
Another benefit of server virtualization is having better control and better capacity management of the storage resources that the virtual servers use. The process of provisioning storage for the applications running on virtual servers is relatively fast and easy compared to traditional block storage provisioning methods. Since storage allocations cam be adjusted, admins can ensure the shared storage is being used most efficiently.
With increased pace of on premise to cloud migration and availability of cutting edge tools that automate the technical aspects of virtualization, adoption of the technology is at its peak. Organizations that can leverage virtualization technology to the fullest will gain a competitive edge over their competitors.
