A collaborative development process for adaptive service deployments

International audienceApplication deployments are complicated tasks especially when dealing with thousands of services and functionalities. Services in an application may require particular execution contexts. Appropriate application deployments are difficult to be achieved when hardware storage, memory, and their interconnections and performance limitations are also taken into account. Without precise descriptions about what requirements are needed by each service, deployment processes could be error prone. In current practices, these descriptions are always considered at the end of development processes which causes application deployments difficult to adapt in different execution contexts. Moreover, reuse of such analysis are rarely considered. In this article, we propose a collaborative approach for describing variable execution contexts and relate them to different application services at a high abstraction level in early development stages. It aims to facilitate deployment tasks with information that provided by system architects to analyse deployment needs of services and to ensure appropriate deployments of services in different execution contexts. A use case of an industrial project is presented with a prototype implementation for demonstrating the approach results
