What : Service-Oriented Reengineering of Legacy JEE applications
Where: Inria Lille B21
When : Friday April 29th at 13h
Abstract:
Service orientation views business applications as orchestrations of reusable services deployed across the enterprise. Service orientation has many purported advantages, including, 1) the packaging of common business and technical functions in a reusable format, 2) IT agility, through the rapid construction of business applications by orchestrating those services, and 3) integrability, thanx to the standardization of invocation interfaces, regardless of implementation technology. Given a legacy enterprise application, it pays to migrate it to an SOA style, to i) capitalize on already implemented reusable functionality, to make it available to other applications, and ii) to facilitate future maintenance and scalability of the application.
Given a legacy Java enterprise application, we propose a three-step SOA migration process:
1) identifying clusters of functionality that could qualify as services
2) package such clusters behind service interfaces, and
3) refactor existing code to invoke the functionality through service interfaces
In this presentation, we will talk about some of the research issues surrounding each one of the three steps, and highlight some of the research directions that we are pursuing.
