Let’s admit it – web services (SOAP) are here to stay for a few more years, and maybe for a long time in some places where there is no business incentive to rebuild them. However, with a decline in new SOAP web services and most applications moving to cloud native architectures, a common query is “how can we support legacy services while moving to microservices?”

Microservices are small, independently-running applications that perform a single function for a larger application or IT infrastructure. By loosely connecting a number of them together, developers create a pluggable architecture that facilitates the process of updating, upgrading, and scaling the application in response to changing requirements.
