# Encouraged by the popularity of my AZ-400 cheat sheet (over 70 views!), I've just published my AZ-204 (Azure Developer Associate) cheat sheet as a LinkedIn article.

AZ-204 is retiring July 31, 2026 and being replaced by AI-200, but ~80% of the core content is still foundational:

- Durable Functions patterns
- Azure Functions tiers (Consumption/Premium/Dedicated)
- Service tiers & limits (App Service, SQL, Cosmos DB, etc.)
- Storage tiers (Hot/Cool/Archive)
- Load balancers (Front Door vs App Gateway vs LB)
- API Management policies (JWT, cache, URL rewrite)
- ETL vs ELT

This is my personal notes summary — not 100% exam coverage, but a solid quick-review companion for AZ-204, AZ-305, and AI-200 foundations.

If you found it useful, feel free to share or drop a comment — and check out my AZ-400 cheat sheet too!
