Availability
Presentation
According to ITIL, Availability is defined as "the ability of an IT service or other configuration item to perform its agreed function when required. Availability is determined by reliability, maintainability, serviceability, performance, and security".
Availability Management is defined as "The process responsible for ensuring that IT services meet the current and future availability needs of the business in cost-effectiveness and timely manner. Availability management defines, analyses, plans, measures and improves all aspects of the availability of IT services, and ensures that all IT infrastructures, processes, tools, roles, etc, are appropriate for the agreed service level targets for availability".
The process of availability management takes into account the period that the service is able to deliver the function it is supposed to between periods of unavailability, the period that it remains unavailable and the cost of that service staying offline.
