It's a big buzzword in the industry, but do you know how virtualization works? We're here to let you in on a little secret - it does more than you think!
Virtualization is more than just server consolidation and resource utilization. Yes, there is an inherent benefit in consolidating servers to reduce the instance of unused resources by allowing multiple operating systems and applications to run on one server.
But the business value of virtualization far exceeds simply reducing your firm’s physical footprint and the number of servers you maintain in your Comm. Room or data center.
Following are some key virtualization features that can allow your firm to operate on an enterprise level without the traditional enterprise investment.
- Resilient, High Availability (HA) Infrastructure
o Virtualization can significantly reduce downtime associated with hardware maintenance.
o Inherent high availability into servers means less hardware purchases and reduced power and cooling costs in the long run.
o Despite multiple virtual machines operating on a single piece of hardware through virtualization, the underlying components provide the option for isolation and dedicated resources to applications.
- Portability to Disaster Recovery (DR)
o Virtual servers are easily portable between physical host servers for flexibility.
o In the event of a disaster or hardware failure, data and applications would remain intact as the virtual machine can be easily started on another server.
- Backup and Restoration
o With virtualization, firms can use snapshots to take images of their servers and desktops and store that information on a storage platform, such as a storage area network (SAN). In a disaster situation, these snapshots can be restored to another server located away from the disaster area if replicated via a SAN, for instance.
o Production snapshots can also be easily taken for debugging or patch testing purposes.
- Ease of Maintenance and Monitoring
o The level of maintenance required to troubleshoot virtualization issues is far less than with traditional server-based infrastructures. Maintenance can be coordinated in a more timely and efficient manner because IT can troubleshoot via remote access.
o Because multiple virtual machines operate on the same piece of hardware, there is a unified approach to monitoring.
