Capacity management
Summary
Capacity management's goal is to ensure that information technology resources are sufficient to meet upcoming business requirements cost-effectively. One common interpretation of capacity management is described in the ITIL framework. ITIL version 3 views capacity management as comprising three sub-processes: business capacity management, service capacity management, and component capacity management.
As the usage of IT services change and functionality evolves, the amount of central processing units (CPUs), memory and storage to a physical or virtual server etc. also changes. 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 making changes to maximize the existing IT infrastructure; for example, tuning the application, or moving a batch cycle to a quieter period. This capacity planning identifies any potential capacity related issues likely to arise, and justifies any necessary investment decisions - for example, the server requirements to accommodate future IT resource demand, or a data center consolidation.
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 of 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 of storage, computer hardware, software and connection infrastructure resources required over some future period of time.
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.
Not all networks are the same.

Network management
Network management is the process of administering and managing computer networks. Services provided by this discipline include fault analysis, performance management, provisioning of networks and maintaining quality of service. Network management software is used by network administrators to help perform these functions. A small number of accessory methods exist to support network and network device management. Network management allows IT professionals to monitor network components within large network area.
