Capacity management

Capacity management

Capacity Management is a process used to manage information technology (IT). Its primary goal is to ensure that IT capacity meets current and future business requirements in a cost-effective manner. One common interpretation of Capacity Management is described in the ITIL framework [ [http://www.itlibrary.org/index.php?page=Capacity_Management ITIL Capacity Management] - The ITIL Open Guide] . ITIL version 3 views capacity management as comprising three sub-processes: business capacity management, service capacity management, and component capacity management (known as resource capacity management in ITIL version 2).

As the usage of IT Services change and functionality evolves, the amount of processing power, memory etc also changes. If it is possible to understand the demands being made currently, and how they will change over time, this approach proposes that planning for IT Service growth becomes easier and less reactive. If there are spikes in, for example, processing power at a particular time of the day, it proposes analyzing what is happening at that time and make changes to maximize the existing infrastructure, for example, tune the application, or move a batch cycle to a quieter period.

These activities are intended to optimize performance and efficiency, and to plan for and justify financial investments. Capacity management is concerned with:

* Monitoring the performance and throughput or load on a server, server farm, or property
* Performance analysis of measurement data, including analysis of the impact of new releases on capacity
* Performance tuning activities to ensure the most efficient use of existing infrastructure
* Understanding the demands on the Service and future plans for workload growth (or shrinkage)
* Influences on demand for computing resources
* Capacity planning – developing a plan for the Service

Capacity management interacts with the discipline of Performance Engineering, both during the requirements and design activities of building a system, and when using performance monitoring as an input for managing capacity of deployed systems.
