Moving to serverless without regretting it

Serverless is a great fit for many workloads — and a terrible fit for others. The marketing rarely draws that line.

Where it wins Bursty traffic, low-to-medium request volume, glue code between services, and edge-rendered content. Zero server management is real value.

Where it hurts Long-running jobs, workloads with strict latency budgets, and heavy stateful services. Cold starts and per-invocation cost add up fast.

The migration playbook Move the read paths first. Keep write and long-running paths on classic infrastructure until the metrics justify the change.
