SOA is an overused acronym utilized in many different contexts to make promises for a bigger and brighter future following a SOA route. These promises are made with very little focus on providing a clear understanding of this path. Exactly how can one take an existing stateful tier based application and move it to this new style of scale-out services model?
In this presentation we will present a three steps approach to that challenge that will focus on minimal and effective migration path between the two models. We will achieve this by demonstrating how to keep the existing programming model the same while focusing on abstracting and replacing the underlying implementations of the middleware stack in a way that will fit the scale-out model. In this way the transition from existing tier based approach becomes significantly simpler and intuitive. We will use Spring and OpenSpaces as the core abstraction platform. For users familiar with Spring the transition is even smoother.
