SOA Basics To Think About

Service Oriented Architecture (SOA) Basics To Think About...

Common Services are defined for all developers to use

The perfect program would simply call existing services SOA is about being pragmatic:

  • Iterative and incremental adoption and build out “Wrap and Reuse” instead of “Rip and Replace”
  • Going back into legacy code that is running fine, rip it apart, insert new functionality is typically not a good idea
  • Sometimes a rewrite in a more open and scalable language is the correct answer
  • The rules to use create and use these services is called governance
    Governance is the BOTH the definition and enforcement of these rules aka policies
