Availability

In IT, availability is simply an expression of the fact that a system is ready to use. Some systems - like the BACS financial transfer system used by banking organisations - are mission-critical.
They must be ready for use at all times for organisations to work. For systems like these, high-availability solutions, where extra investment has been made to avoid failure and downtime are essential.
