The promise was that nobody would manage servers again. The reality is that functions excel at short, event-driven work and struggle with anything stateful or latency-sensitive. Teams have settled into a pragmatic mix, and vendors have stopped pretending otherwise.
Where functions still win
Webhooks, scheduled jobs, image processing and anything that runs rarely but must scale instantly. The cost model is unbeatable for low, bursty volume. For steady traffic, a container is cheaper and easier to debug.
Key takeaways
- Functions dominate event-driven glue
- Steady workloads favour containers
- Vendors now market hybrid architectures
