Dos and Don'ts for Serverless and Azure Functions

on YouTube ↗01h 01m

" summary

Practical serverless rules for Azure Functions: use function app = unit of deployment and scale, prefer bindings (Cosmos DB example) over manual SDK glue, install extensions via NuGet, and hook Application Insights for observability. Reuse heavy clients (for example reuse HTTPClient as a singleton or a static SQL client) to avoid socket exhaustion. A home doorbell prototype runs for ~$4/month versus an $80 VM; load testing shows automatic scale to nine instances ~500 req/s. Use durable functions replay orchestrator for long-running, stateful workflows and fan‑out patterns.
