Everyone is talking about it as if everyone can provide it, one way or another. Once you dig just slightly below the surface it becomes apparent that there are nearly as many definitions for availability as there are vendors touting it. Some consider availability of the data, while others availability of the server or storage subsystem.
At its core availability is defined as "present and ready for use; at hand; accessible". The level of availability depends on an organization's service level. Once the business needs for availability are understood, appropriate solutions can be researched and identified. Check out this white paper to "Breaking Through the Noise of Application Availability."
