TARGETED CAPACITY PLANNING: DELIVERING A BUSINESS FOCUSED, COST EFFECTIVE SERVICE

摘要

In today's ITIL based world the focus of IT Service Delivery is on the management and support of services to its customers: The business. These services, primarily based around applications designed to deliver products to external customers, have widely varying IT infrastructure requirements and business value.rnConversely, the Capacity Planning group was predominately organised along architectural platform lines, focussing separately on mainframe, midrange Unix and Linux, Windows, network and storage architectures.rnWhile creating a business-focused capacity plan for an application using a single architecture was, in theory, simple under this organisational structure, complex, multi-platform applications, however, were not readily supported. To fully understand the capacity impact of changes in business demand on these applications it was necessary to build an end-to-end view of the application and to report capacity utilisation across the relevant platforms.rnSupport for both platform based and end-to-end capacity planning clearly required a different organisational framework. This presentation covers the development of a framework with a multi-tier approach to delivering its capacity monitoring, reporting, analysis and forecasting service. It also describes our journey towards implementing end-to-end capacity planning under this framework.
