Uploaded: 2026-04-21T00:00:00Z
Description: This chapter covers how Lambda processes events, handles retries and failures, and connects to private resources. You'll learn the difference between synchronous and asynchronous invocations, how event source mappings batch records from queues and streams, and how to route outcomes with DLQs and destinations. You'll also see how VPC networking impacts connectivity and cold-start performance.
