Modernize Legacy Systems Using an SOA Approach
To remain competitive, the organization has to modernize its IT systems. Modernized IT solutions must create new value from existing systems and provide flexibility and easy interoperability among a broad set of technologies - usually a challenge with legacy applications. Service-Oriented Architecture (SOA), widely adopted by organizations in recent years, offers a practical solution for evolving and reusing existing assets. This paper shows a typical approach to modernizing the legacy systems, including identifying the IT pieces that must be augmented with new features, determining how the required augmentations are performed, exposing each capability through a modern interface, and using the newly exposed services to automate future business processes.
