Azure Functions

This covers the modern Azure Functions programming models across .NET isolated worker, Python v2 decorators, and Node.js v4, plus production patterns like Durable Functions orchestration and cold start mitigation. The sharp edges table is genuinely useful, calling out the usual suspects: blocking async calls, HttpClient misuse, and the fact that you should really be using the isolated worker model for new projects instead of the legacy in-process one. Good coverage of timeout configs, Application Insights setup, and warmup triggers. Lean on this when you're past the basics and need to avoid the performance traps that bite most teams in production.
