Virtualization
Oversee and administer the operation of the virtualization environments, including the collective processes, tools, and technologies to ensure governance and control over the virtualized infrastructure.
Improvement Planning
Practices-Outcomes-Metrics (POM)
Representative POMs are described for Virtualization at each level of maturity.
- 2Basic
- Practices
- Experiment and build experience of virtualization and its management tool sets.
- Demonstrate and communicate the advantages of virtualization.
- Outcomes
- Virtualization is emerging for limited parts of the IT infrastructure.
- The organization gains confidence in the use of virtualization and sees its advantages — for example, in reduced costs (via consolidation), improved disaster recovery, and so on.
- Metrics
- # of virtual versus physical servers.
- % cost reduction due to virtualization.
- 3Intermediate
- Practices
- Adapt the IT infrastructure management processes to move to an all-virtual world.
- Invest and gain experience in virtualization-aware management tools to orchestrate the relationship between large numbers of dynamically changing VMs, physical servers, storage, and network resources.
- Outcomes
- The default environment has shifted from server to virtual server.
- Operational savings increase, and VM sprawl is controlled and reduced.
- There is partial automation, leading to improvements in key processes such as change management, incident management, and deployment.
- Metrics
- % virtualization of the IT infrastructure.
- % automation of the virtual environment.
- 4Advanced
- Practices
- Remove the division of workloads between business units by shifting virtualized resources so that they become a pool that is managed at the pool level.
- Substantially increase automation.
- Outcomes
- The management of the IT infrastructure is transformed to provide shared services across the organization.
- Administrators take full advantage of automation tools to update and manage the virtual environments.
- Application deployment is automated.
- Metric
- # of shared infrastructure services.
- 5Optimized
- Practices
- Put in place a centre of excellence to optimize and manage virtualization policies, procedures, and standards.
- Provide optimized and secured environment access across and beyond the organization, including portals for business partners.
- Outcomes
- An optimized virtual environment is driven by organization goals and business-driven scenarios to significantly reduce risks.
- The appropriate level of environment access is provided to each constituency.
- Metrics
- # of virtualization improvements and optimizations.
- # of access levels provided.
