Abstract :
A progressive-evolution strategy for migrating systems to service-oriented architectures should minimize the risk to investments in existing software systems while letting businesses exploit the benefits of services. In principle, hybrid systems combine services with nonservice elements. SOAs present a compelling vision for businesses. Conceptually, services bring together a layer of business functionality and a layer of technological implementation.
