APAM overview

A service is dynamic if it can appear and disappear, without notice, during run-time. A dynamic application is made, at least partially, of dynamic services.

APAM (APplication Abstract Machine) is an extensible service platform dedicated to support the execution of concurrent dynamic applications.

APAM aims to simplify the design, development and execution of applications that must provide a "constant" service in a moving and unpredictable context, and in the presence of other, potentially competing, applications.

The APAM system is made of the APAM machine (also called APAM core) and a number of managers (APAM plugins) that are designed to support collectively the execution of concurrent dynamic applications. Here, we present a general view of APAM.

• APAM machine - a brief introduction to the APAM core and of its main handled concepts.
• APAM system - a short presentation of the APAM system, its architecture, and the current available managers.
