A virtual datacenter is a pool of cloud infrastructure resources designed specifically for enterprise business needs. Rather than the traditional approach of “one server per application” which inevitably results in underutilized resources, with a virtual data center approach compute resources are dynamically applied whenever and wherever they exist to more effectively serve a dynamically changing business. When the concept of virtualization is applied to the entire data center, IT can become the enabler to more quickly and cost-efficiently add new and more experimental business capabilities.
Data center virtualization will come in handy as enterprise computing demands grow in terms of bandwidth and processing intensity. For example, according to Cisco, the number of workloads per installed traditional server will increase from 1.5 in 2011 to 2.0 in 2016. Meanwhile, the number of workloads per installed cloud server will increase from 4.2 in 2011 to 8.5 by 2016. In fact, by 2016, nearly two-thirds of all workloads will be processed in the cloud.
As such, virtual data centers can help organizations save money by consolidating work on fewer servers while shifting expenditures from Cap-Ex (capital expense) to more flexible operating expenditure (Op-Ex) budgets. Importantly, with inherent fail-back and recovery, virtual data centers offer improved business continuity. To realize these benefits, organizations should carefully choose providers with the business and technical expertise needed to ensure a smooth migration.
RESULTS TO EXPECT
When working with an external service
provider, you should ensure that it can:
- Provision a virtual data center specific to your
application and service needs for availability.
- Provide enterprise-grade security and balancing of
- Maintain multiple service profiles with policy
- Assure platform redundancy and high-performance
information lifecycle management (ILM) for storage.
- Deliver massive scalability for all data center
- Manage and monitor the cloud environment.
Security can be challenging, particularly in public, multi-tenant clouds where like-systems serve multiple customers. By working with a global services provider, companies immediately gain process maturity as well as data integrity and protection that comes with their years of experience safe-guarding and isolating client applications and data from security breaches.
Data centers are becoming more virtualized and "service-centric" every day. As business evolves, the data center must evolve with it. Both the cloud and virtualized data centers that run in them represent a new information delivery model, one that if properly harnessed can cost-effectively power today’s asset-light operating models.
