1) Camunda BPM is used at 1&1 as part of their Service and Process Platform to enable process automation. 2) It utilizes various tools for process modeling, development, execution, monitoring and more as part of its tool chain. 3) The Process Service Invocation component allows integrating external systems and services into processes through request and response adapters that handle injection and extraction of variables and correlation values.
