Around the world, IT organizations are on the same journey to virtualized, cloud, and software-defined data centers. These next-generation data centers virtualize IT resources to enable the pooling and sharing of infrastructure components, to increase IT agility, and to improve the economics of data center operations. This forward-looking approach to the data center creates a new set of performance management challenges that arise in virtualized environments. In this new era for IT, application workloads are not tied to dedicated servers, storage, and network resources. Instead, they move dynamically to balance workloads and optimize infrastructure utilization. The fluid nature of the data center changes the ground rules for performance management. It becomes more difficult to ensure service levels and application performance.
