Overutilization vs Underutilization of Virtual Machines

Does virtualization truly improve utilization?

If so, shouldn’t cost be lower as a result?  Well, maybe in the short term…  but in the long term we are starting to see cases where costs accumulate over time and virtualization ends up being more expensive.

Gravitant’s response:
“Over-provisioning of Virtual Machines has resulted in Virtual Machine sprawl, which is difficult to manage.  This has resulted in higher cost over time.  On the other hand under-provisioning results in lower performance and SLA penalties.” – Mohammed Farooq, CEO Gravitant

Gravitant’s capacity planning tool configures the optimal physical and virtual machine landscape of servers, network, and storage to

1. Minimize VM Sprawl
2. Meet application performance thresholds
3. Reduce data center costs – systems and operations

Operations Research tools are used to balance the tradeoff between cost (due to sprawl) and performance (from SLAs).
