Abstract

This article explores seven common misconceptions about service-oriented architecture (SOA):

  1. SOA provides the complete architecture for a system.
  2. All legacy systems can be easily integrated into an SOA environment.
  3. SOA is all about standards, and standards are all that is needed.
  4. SOA is all about technology.
  5. The use of standards guarantees interoperability in an SOA environment.
  6. A service registry allows service binding dynamically at runtime.
  7. Testing SOA-based systems is no different from testing any other type of system.
