In this talk, Kim introduced the concept on how to refactor the legacy systems to serverless architecture. In order to remove the "integration/glue" code from application code, we can well utilize the platform capabilities to do. Lambda destination, Step Function Pipe are classic features could help on this. Suggest each one developer could re-think about how to leverage platform vendor offered services to build up solutions but keep a clean & simplified architecture design.
