Advanced Topic 42 of 51 Distributed Systems & Cloud

Serverless Computing

Running functions without managing servers.

How it works

Functions-as-a-Service (Lambda) run code on events with automatic scaling and per-invocation billing; no server management but with cold starts and execution limits.

Where it is used

Event handlers, APIs with spiky load.

Common pitfall

Vendor lock-in and difficulty debugging locally.

Where it fits in the course

Serverless Computing is topic 42 of 51 in Distributed Systems & Cloud, rated Advanced. It follows Kubernetes. The next topic is Infrastructure as Code.
