Capacity Planning for the Management Platform
The management platform sizing means sizing for the following components that provides the functional capabilities
- Service Request Management
- Service Automation
- Service Provisioning
- Service Monitoring & Management
- Service Level Management
- Service Usage & Accounting
Further the sizing will be affected based on the non-functional consideration that needs to be addressed by each of these components of the management platform. One should review the performance reports and workload pattern/handling capabilities of each of the products selected to validate the sizing considered can meet the non-functional requested by the solution.
The size of the management platform depends on the size of the managed environment. It is
preferred to keep a centralized management environment and scale it as needed
when the managed environment grows. This is often not an easy calculation or simple process. Need to apply pure engineering to plan the capacity for each capabilities. Apart from the capabilities discussed above, the following key areas also needs to be covered
- Asset Management
- Energy Management
- Network Management
- Security Management
- Storage Management
- Service Availability Management
- Virtualization Management
- What operations are expected to be performed with management platform?
- What are the average and peak concurrent administrator workloads?
- What is the enterprise network topology?
- What is the expected workload for provisioned virtual servers, and how do they map to the physical configuration?
- For the provisioned servers: What is the distribution size?
- What are the application service level requirements?
