Serverless compute
No servers to patch, and a bill of zero when nothing runs. In exchange you accept a 15-minute ceiling, cold starts, and the fact that your function may run twice for one event.
Chapters
- How Lambda executes your codeServerless compute removes the operating system layer, but forces you to work within memory and execution time ceilings.
- Why concurrency is the true unit of Lambda capacityLambda scales by running multiple instances of your function in parallel, and managing this concurrency prevents database overload and application throttling.
