What is virtualization? Server virtualization is the process of running multiple servers off one physical box, thus allowing you to run multiple applications on fewer physical servers, and save money in the long haul.
As servers become more powerful, running a single server for a task creates additional overhead, additional costs, and the server itself remains underutilized. With virtualization, you can launch a new server, increase memory or processing power, and expand storage in minutes, as opposed to hours. Virtualization also makes disaster recovery more possible (details below), offering you peace of mind and greater flexibility in the event of a server crash or data center loss.
Need more reasons to Virtualize? We’ve listed a few for you!
- Energy Savings
- Lower your energy bills and go Green!
- Launch new servers without the need to order new equipment
- Lowers setup and implementation costs
- Increased uptime
- With a virtualized environment you can move virtual machine from one host to another, migrate storage, and create clusters of servers with ease.
- Improved Disaster Recovery
- Virtual machines can be backed up as a whole. These image backups can be reverted and placed back into your production environment in the event of a disaster, avoiding days or even weeks of down time.
- Separating tasks
- Some server applications prefer to run on their own box. In addition, certain software vendors will not support an application if it shares a server with a conflicting program. Virtualization allows you to isolate applications to their own server, and simplifying maintenance.
- Extending the life of older applications
- Legacy applications which require older operating systems for maximum functionality can be preserved by launching a virtual machine hosting an older environment running your legacy programs. This allows you to save licensing costs and skip a generation of future software releases if you so choose.
The image below, provided by vmware.com, illustrates just how virtualization works. Typically, traditional standards would entail 1 server per application or purpose. Servers remain under utilized and their CPU and Memory availability goes to waste. Enter – Virtualization! By virtualizing the environment, every CPU and ounce of Memory is utilized to it’s fullest, allowing you to save money in the long run, lower overhead, and decrease your hardware footprint.
