Virtualization has come the forefront of every enterprise's favorite money-saving initiative. By reducing the numbers and types of servers that support their business applications, companies are looking to reduce costs.
Less power usage, both from the servers themselves and the facilities' cooling systems, and fuller use of existing, underutilized computing resources translate into a longer life for the data center and a greater bottom line. And a smaller server footprint is easier to manage.
Some virtualization-enabled features and capabilities worth considering: high availability, disaster recovery and workload balancing.
Beyond the cost savings, virtualization can greatly enhance an organization's business agility. Companies that utilize clustering, partitioning, workload management and other virtualization techniques to configure groups of servers into reusable pools of resources are better positioned to respond to the changing demands their business places on those resources.
This technology offers the potential for a fundamental change in the way IT managers think about computing resources. When managing individual boxes becomes less challenging, the focus of IT can shift from the technology to the services the technology can provide.
IT departments everywhere are being asked to do more with less, so resource utilization is necessary. Virtualization technologies offer a direct and readily quantifiable means of achieving that mandate by collecting disparate computing resources into shareable pools.
Turning a swarm of servers into a seamless computing pool can lessen the scope of future hardware expenditures, while putting the economies of things like utility pricing models and pay-per-use plans on the table. A server virtualization strategy can open up valuable rack space, giving a company room to grow.
Virtualization can go a long way toward reducing the physical requirements of the data center, but it can also compound the level of management complexity of those servers. So look for solutions that provide cross-platform systems management for both the virtual and physical machines.
Using virtualization you will be able to migrate your organization's legacy applications and existing operating systems, without modification, onto virtual partitions. This migration should make it simpler to enhance the performance of those applications, but you'll need a solution that supports the integration of virtualization with legacy management tools.
Virtualization is no longer just about server consolidation. Flexibility is another key benefit of the technology. In virtualized environments, it's easier to move things around, to encapsulate, to archive and to optimize.
