Software Defined Infrastructure [SDI]
Develop and implement approaches and policies so that the IT infrastructure can be fully deployed and controlled by an application/code (this combines composable and converged/hyper-converged infrastructure systems with software-defined networking, storage, and compute, to build and manage the IT infrastructure).
Improvement Planning
Practices-Outcomes-Metrics (POM)
Representative POMs are described for Software Defined Infrastructure [SDI] at each level of maturity.
- 2Basic
- Practice
- To prepare for SDI, complete the virtualization for most of the server infrastructure, and start the virtualization of the storage and network infrastructure.
- Outcome
- The IT infrastructure is being prepared for the implementation of SDI by an increase in the level of virtualization, and is now primed to start pooling resources.
- Metric
- % server, storage, and network virtualization.
- 3Intermediate
- Practices
- Pool resources and provide automatic provisioning of IT servers, storage, and networks.
- Provide the tools to support the creation of self-service portals.
- Outcomes
- IT infrastructure resources are pooled and are automatically provisioned.
- Supporting tools enable the creation of self-service provisioning portals.
- Metrics
- % of resource pooling for servers, storage, and networks.
- # of self-service portals.
- 4Advanced
- Practices
- Use orchestration to optimize the allocation of data centre resources.
- Use automation and orchestration to manages performance issues, and to decide on the appropriate remedial actions.
- Outcomes
- Data centre resource allocation is optimized.
- Performance issues are automatically identified and resolved.
- Metric
- % orchestration of the IT infrastructure.
- 5Optimized
- Practices
- Use IT service management software to maintain the agreed service levels for each application and service.
- Automatically assign resources to maintain compliance with service levels with no manual intervention.
- Outcomes
- Service levels are automatically maintained to be in compliance with service level agreements with little or no manual intervention.
- The environment ensures that all services and applications have the resources for optimal performance.
- Metrics
- % of the IT infrastructure controlled by IT service management.
- # of times that manual intervention is required to maintain the optimal IT infrastructure.
