### Pre-Filled Template & Production Source

# Serverless Functions taste of a cloud backend engineer
- Keep each function small and focused on one trigger, but group closely related HTTP routes in one handler to cut cold starts. Confidence: 0.80
- Initialize SDK clients and database pools outside the handler so warm invocations reuse them. Confidence: 0.95
- Use a connection pooler or an HTTP-based database driver, since thousands of concurrent functions will exhaust direct Postgres connections. Confidence: 0.90
- Set an explicit timeout and memory size per function instead of accepting platform defaults. Confidence: 0.85
- Keep bundles small with tree-shaking and lazy imports, and measure cold start time after every major dependency change. Confidence: 0.85
- Make every event handler idempotent, because queues and event sources deliver at least once. Confidence: 0.95
- Move slow or retryable work to a queue and return quickly from HTTP functions. Confidence: 0.90
- Send failed async events to a dead letter queue with an alert on its depth. Confidence: 0.90
- Define functions, permissions and triggers as code with SST, Serverless Framework, SAM or Terraform, never by clicking in the console. Confidence: 0.90
- Grant each function its own least-privilege role scoped to the exact resources it touches. Confidence: 0.95
- Load secrets from a secrets manager or the platform's encrypted env vars, never from the repo. Confidence: 0.95
- Write structured JSON logs with a request ID and correlation ID on every line. Confidence: 0.90
- Trace requests across functions and queues with OpenTelemetry or the platform's tracing. Confidence: 0.80
- Keep business logic in plain modules and keep the handler a thin adapter, so it can be unit tested without the cloud. Confidence: 0.90
- Run integration tests against a real deployed stage per pull request rather than trusting local emulators. Confidence: 0.80
- Set reserved or maximum concurrency on functions that call fragile downstream services. Confidence: 0.85
- Use provisioned concurrency only for latency-critical paths where cold starts were measured to hurt. Confidence: 0.75
- Prefer the arm64 runtime when dependencies support it for better price per performance. Confidence: 0.70
- Set billing alerts and per-function cost dashboards before launch, not after the first surprise invoice. Confidence: 0.85
- Avoid chaining functions that call each other synchronously; use events or a workflow engine like Step Functions instead. Confidence: 0.85
- Choose containers or long-running services for steady high-throughput workloads where serverless costs more. Confidence: 0.75
