However, the identification of such services is not a trivial task. A number of questions must be answered. Should one begin by deriving services from the legacy application, or rather start with all potential services and decide which would fit actual business requirements? Also, if certain services are required, what is the best way to find them within a typical legacy application? And, what is the most suitable degree of granularity at which they should be defined? This article answers such questions and develops a rational and systematic approach for locating and extracting services from legacy environments in support of SOA and service-oriented computing.
