Lambda Core Concepts
A Lambda function has code, configuration, an execution role and a runtime. Invocations can come from AWS services or direct API calls.
Why it matters
Understanding the execution model helps you decide whether a workload fits serverless compute.
How it works
Event → function invocation → execution → response/logs → scale down when idle.
Core Concept
A function has code, runtime settings, permissions, environment variables and resource limits.
