Capacity Management
Capacity Management needs to ensure that sufficient resources and performance is
available to meet the demands of the business. Essentially, capacity management
is a balancing act as it tries to balance the cost of supplying a service
against the need for the service, as well as ensuring there is enough of the
service to meet the demand. Simple Supply and Demand.. 101!
It
has 3 areas of responsibility namely:
-
Business Capacity Management
-
Service Capacity Management
-
Resource Capacity Management
Business Capacity Management takes the need and plans of the business, both
current and future, and translates the information into requirements that can be
used to extend or transform the service delivery and infrastructure. Managing,
controlling and predicting the performance and capacity of services that are
being delivered is part of both Service and Resource Capacity management. The
usage of the end-to-end service and the workloads on that service forms part of
Service Capacity Management, whereas Resource Capacity Management is concerned
with the individual components of the service.
There are a number of similarities on each of the areas of responsibility, but
each has a distinct difference, and that is Business Capacity Management is
focused on the current and future business requirements, while Service Capacity
Management is focused on the delivery of the existing services that support the
business and Resource Capacity Management is focused on the
infrastructure that underpins service provision,
