In this interview, Kevin Israel, Visual Studio Team System MVP, shares with Zhiming Xue his thoughts on implementation of a hybrid architecture based on SOA and ROA in the enterprise space. Kevin explains what Resource Oriented Architecture (ROA) is and, through examples, highlights its key differences from Service Oriented Architecture (SOA). He argues that while the two architectural patterns share the same common problem domains such as versioning and application manageability, they work differently in practice. ROA services or RESTful services may be used to bring resources to the user, whereas SOA services are typically created to process business logic. Therefore, the crux of the hybrid architecture implementation is to use them together and use them for their intended purposes. Kevin believes that as cloud computing and enterprise meshup applications start to emerge, more applications based on the hybrid architecture of SOA and ROA may be seen in the enterprise.
