Serverless Architecture

Serverless architecture is the broader build-versus-operate decision: running custom automation logic on managed infrastructure that the vendor maintains, scales, and bills by execution rather than by reserved capacity.

It includes event triggers, managed databases, and functions — not just the function-execution model itself. It removes server maintenance but introduces cold-start delays and potential vendor lock-in.

A practical example

Example: a RevOps team building glue code between their marketing platform and CRM can deploy it as event-triggered functions on managed infrastructure, paying nothing when no events arrive, instead of maintaining a small always-on server.

What to evaluate before investing

  • What are the cold-start characteristics, and do they affect time-sensitive workflows?
  • How portable is the logic if you leave — are triggers and state tied to vendor-specific services?
  • How does execution-based billing behave under sustained high volume compared with reserved capacity?

Limitations and tradeoffs

Scaling to zero means the first execution after idle can be slow; workflows that must react within seconds may need provisioned capacity, which erodes the cost benefit.
