Migrating Legacy Applications—Challenges in Service Oriented Architecture and Cloud Computing Environments

Approaches to service oriented architecture and cloud computing almost always assume starting a system from scratch, which for many otherwise potential customers is not viable for financial or other reasons. Here computer scientists explore ways to fold older software into such networked systems. Their topics include research challenges in the maintenance and evolution of service-oriented systems, re-engineering and wrapping legacy modules for reuse as web services, the migration of data between cloud and non-cloud datastores, a report of experience migrating a legacy web-based document-analysis application to Hadoop and HBsa,e and the model-driven integration of heterogeneous software artifacts in service oriented computing.
