Server Virtualization has been around for a while and is quietly gaining grounds in the IT Infrastructure world. In simple terms it allows to run multiple servers simultaneously on one physical computer. It is an amazing technology but not a lot of people are aware to the enormous advantages that virtualization brings to the table. Some businesses are still hesitant to embrace the power of virtual machines, but should they give the following benefits:
- Improved Disaster Recovery – not only virtual servers are relatively less susceptible to hardware-induced errors but they can also be started off a lot faster than a physical server in disaster recovery situations. And with a proper backup in place, you can easily move virtual servers across physical servers in the event of a hardware failure. With fewer servers, you can also save on the cost of your cross-network replication site.
- Increase Server Efficiency – virtualization technology now have advanced features which enables fault-tolerant, high-availability and load-distribution mechanisms leading to server’s overall higher performance.
- Better Server Management – you can easily share and allocate any resources such as processors, memory or you can easily expand hard drives as you deem necessary for your virtual server.
- Power Saving – this is one of the most obvious advantage of virtualization. Having servers consolidated on fewer physical servers means lower monthly power consumption and cooling expenses in server rooms or datacenters.
- Space Reduction – having less number of physical servers will not only save you physical space and make server rooms look a lot tidier but will also save you financial costs in case the company decides to rent space over datacenters.
- Extend Legacy Programs – some companies use legacy programs that are no longer supported by newer operating systems or have compatibility issues. With virtualization technology, you can certainly extend the life of these programs by virtualizing the old machine and house it in a newer and faster physical host.
- Reduce Operating Costs – with all of the technological advantages of virtualization, it also goes hand-in-hand with lesser overhead costs starting from power consumption, space rentals, business continuity, and flexibility in server management.
Virtual machines now offer powerful means of significantly reducing typical maintenance issues to IT engineers. If you haven’t tried it yet, now is the time to start – and experience firsthand the abovementioned technological and economic benefits.
