What is a Service Registry?
Updated Apr 28, 2026
Short answer
A directory where service providers can publish their services and service consumers can discover them.
Deep explanation
SOA focuses on integrating disparate systems using standardized interfaces. By abstracting business logic into services, organizations can leverage legacy systems while building new capabilities. It relies heavily on XML-based standards and centralized governance through an ESB.
Real-world example
A banking system where 'GetBalance' and 'TransferFunds' are discrete services accessible by web, mobile, and branch apps.
Common mistakes
