CASA

Overview

In today's world of highly dynamic computing environments, dynamically adaptive applications are the need of the hour. CASA (Contract-based Adaptive Software Architecture) provides a framework for enabling the development and execution of dynamically adaptive applications.

The key features of CASA are:

  • Separation of the adaptation concerns of an application from its business concerns,
  • A runtime system for dealing with the adaptation concerns,
  • Support for adaptation at various levels of an application -- from lower-level services to application code,
  • A contract-based adaptation policy facilitating changes in the adaptation policy at runtime.
