Availability Management targets allowing organisations to sustain the ITIL management-availability to support the business at a justifiable cost. The high-level activities are Realise Availability Requirements, Compile Availability Plan, Monitor Availability, and Monitor Maintenance Obligations.
Availability Management addresses the ability of an IT component to perform at an agreed level over a period of time.
* Reliability: Ability of an IT component to perform at an agreed level at described conditions.
* Maintainability: The ability of an ITIL framework to remain in, or be restored to an operational state.
* Serviceability: The ability for an external supplier to maintain the availability of component or function under a third-party contract.
* Resilience: A measure of freedom from operational failure and a method of keeping services reliable. One popular method of resilience is redundancy.
* Security: information retrieval systems may have associated data. Security refers to the confidentiality, integrity, and availability of that data. Availability gives a clear overview of the end-to-end availability of the system.
