What is Availability?

Availability is defined as a fraction of time the system is providing service to its users. With the ubiquity of computer and systems, the importance of high availability is being recognized. In this website we provide definitions and information on modeling methodologies, important books and articles on this topic. We also provide information on software packages that have been used for availability predictions of real-life systems.
