Explanation
Capacity management is a process that ensures that the IT resources of an organization are sufficient to meet the current and future demands of the business. Capacity management enables organizations to identify the extent to which components need to be upgraded, by monitoring and analyzing the performance, utilization, and availability of the IT components, such as servers, networks, storage, applications, etc., and identifying any bottlenecks, gaps, or risks that may affect the service level agreements (SLAs) or quality of service (QoS).
Capacity management also helps organizations to plan and optimize the use of IT resources, by forecasting the future demand and growth of the business, and aligning the IT capacity with the business needs and objectives.
Forecasting technology trends is a possible outcome of capacity management, but it is not its main purpose.
Establishing the capacity of network communication links is a part of capacity management, but it is not its main goal. Determining business transaction volumes is an input for capacity management, but it is not its main objective.
