Application Interface Specification

The Service Availability Forum™ Application Interface Specification (AIS) standardizes the interface between Service Availability Forum™ compliant High Availability (HA) middleware and service applications.

New: Release 5 - October 2007

Release 5 offers enhanced specifications that address the critical areas of security, software management and Java integration, while augmenting existing services and maintaining backwards compatibility.

Major highlights and functionality of Release 5:

Software Management Framework - This is the first release where the fundamental functionality to upgrade running systems are fully described and outlined. The framework covers rolling upgrade functionality, but also incorporates provisions to support other forms of upgrade mechanisms and extended functionality in the future.
Security Service - This initial security specification provides basic functionality. It acts as a starting/integration point for future security additions needed in high availability middleware implementations.
Java Integration – Introduces functionality needed to enable use of Java with the Availability Management Framework (AMF). Future work will include additional functionality to drive adoption in the Java Community Process (JCP).
