Adaptation objectives, actions and properties are among the main facets of adaptability. They are studied and classified in this section. Two different adaptability views may be distinguished: the design time adaptability [8] and the run time adaptability [4, 3]. For the first view, we can find design support tools like Adaptive Application Architecture (AAA). This tool handles the application development cycle and optimizes the resource value by insuring that the infrastructure answering clearly and in a measurable way to activity requirements. For the run time adaptability [10] presents several adaptation techniques among which use proxy services, change model of interaction and reorganize application structure. Adaptation approaches are also targeting different architectural levels including Service, Middleware and Transport levels.
