Thomas Erl brings you the first SOA Pattern of the Week, a series comprised of original content and insights provided to you courtesy of the authors and contributors of the SOAPatterns.org community site and the book “SOA Design Patterns.” One of the fundamental goals when designing service-oriented solutions is to attain a reduced degree of coupling between services, thereby increasing the freedom and flexibility with which services can be individually evolved.
The Policy Centralization pattern advocates that we keep a reusable policy in a single definition and have service contracts to which the policy applies, link to and share this definition. A policy expresses a set of requirements or rules that service consumers usually must adhere to in order to invoke and interact with a service.
