Open Architecture for Building Large Scale Deployment Systems

摘要

Deployment encompasses activities for installing and updating a released software system. These activities include the deployment of a system onto a host and upgrade of an already deployed system. In this paper we describe a generic and open approach intended to support software deployment onto networks of distributed sites. We rely on process centered systems to face usual deployment difficulties. We first describe how we exploit a process centered system to go towards a deployment environment. Process systems have the ability to manage, coordinate and monitor tasks and allow derived environments to be very flexible. In a deployment context they allow administrators to change the deployment process without changing the domain specific technologies. Our deployment environment, ORYA, provides environmental support for deployment process modeling and execution. This paper discusses deployment concepts and focuses on the presentation of ORYA environment designed with customization, process-independent deployment, flexibility and tools interoperability as chief considerations.
