Serverless Architecture: Where It Helps and Where It Doesn't

Serverless functions remove the burden of managing servers and scale automatically, which is genuinely useful for spiky, unpredictable workloads like image processing or webhook handling.

The tradeoffs show up with cold starts affecting latency-sensitive requests, and costs that can become unpredictable at very high, sustained traffic compared to a fixed server.

We use serverless selectively, for background jobs and event-driven tasks, while keeping core request-handling on traditional infrastructure when latency and cost predictability matter more.
