CORE DEFINITION

Extract auxiliary functions (such as monitoring, logging, security) from the main application and place them in a separate container (sidecar), deployed together with the main program, just like a motorcycle sidecar. Scaffolding role: functional decoupling. It reminds us that core business logic should be as pure as possible. Stripping off the common, non-business 'dirty work' (like logging) to the 'sidecar' can reduce system complexity.
