What is SOAP and how is it used in SOA?
Updated Apr 28, 2026
Short answer
A protocol for exchanging structured information in Web Services using XML.
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
