<\/a><\/p>\nValue of Capacity Management<\/b><\/h3>\n
Capacity management provides several benefits to the business. Some of them are:<\/span><\/p>\n\n- Improvement in performance and availability of IT services.<\/span><\/li>\n
- Distinguishing the activities which are long-term and strategic from the ones which are day-to-day operational tasks.<\/span><\/li>\n
- Reduction in problems and incidents related to capacity and performance.<\/span><\/li>\n
- Focusing the awareness on proactive considerations while dealing with capacity matters.<\/span><\/li>\n
- Making sure that the required capacity and performance are provided in a manner that is very cost-effective.<\/span><\/li>\n
- Using a forward-looking capacity plan to improve the reliability of capacity-related budgeting.<\/span><\/li>\n<\/ul>\n
Principles and Basic Concepts of Capacity Management<\/b><\/h2>\n
Capacity management is mainly about the management of relationships between the 3 variables – resources, workload, and service levels, which are interconnected. It is a balancing act involving:<\/span><\/p>\n\n- Balancing the costs incurred against the resources required<\/span><\/li>\n
- Balancing the supply against demand<\/span><\/li>\n<\/ul>\n
Capacity management relies on three sub-processes to deliver results as it is a complex and demanding process. They are:<\/span><\/p>\n![\"capacity](\"https:\/\/www.invensislearning.com\/blog\/wp-content\/uploads\/2021\/06\/Picture102.png\")
<\/strong><\/p>\nBusiness Capacity Management<\/b><\/h3>\n\n- \n

- It is the driving force for the whole process.<\/span><\/li>\n
- The updates to the business plans encapsulate the long-term strategy of an organization.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
Service Capacity Management<\/b><\/h3>\n\n- \n
\n- Capacity management should understand the resources, working patterns, peaks, and lows of the IT services. By doing so, they can contribute to the service by meeting its service level agreement targets.<\/span><\/li>\n
- Service capacity management predicts, manages, and controls the end-to-end performance of the operational IT services and their workloads.<\/span><\/li>\n
- The main focus is on managing the performance of the service as it is determined by targets contained within the service level agreements or requirements.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
Component Capacity Management<\/b><\/h3>\n\n- \n
\n- It involves foreseeing, handling, and governing the performance, utilization, and capacity of individual IT components.<\/span><\/li>\n
- Every hardware component and many software in the IT infrastructure have a definite capacity that can be measured, and when it is exceeded, can lead to performance-related issues and other problems.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
