Integration
What is Middleware?
Software that connects applications by routing, transforming, and monitoring messages between them.
SAP examples include PI/PO and Integration Suite; non-SAP examples include MuleSoft, Boomi, and Azure Integration Services. Middleware is a common place for interface defects. Integration testing must include middleware monitoring.
