About AWS Lambda: Execution Model, Scaling, and Operational Reality

Copied

How Lambda actually runs your code: the handler contract, the three invocation paths and their retry semantics, the execution-environment lifecycle behind cold starts, and the levers (memory, concurrency, provisioned capacity, SnapStart) that control latency and cost. Students finish able to design idempotent, least-privilege functions, package and observe them properly, and — just as important — recognize the workloads where Lambda is the wrong tool.
