Serverless Sidecar Pattern for Offloading Auxiliary Logic

May 05, 2021

Had this idea and just getting it down on paper.


  • Your core business logic lives in containerized application, running on Kubernetes. (your org or team is not fully bought in to cloud native and serverless :)
  • Your write serverless functions (e.g. AWS Lambda) to handle auxiliary logic
  • The serverless functions can be triggered via DynamoDB streams, events, etc.
  • How far can or should this be taken?
  • Serverless functions calling the core application’s REST APIs?
