Inside the course
Explore gateway and management responsibilities, then compare REST with OpenAPI and APIs with SDKs. Consider services and microservices, study an online-store scaling example, and finish with the GraphQL-versus-REST comparison.
Try this learning exercise
Draft a small catalogue API on paper with a few resources and request examples. Explain which concerns belong in application code, which a gateway might handle and when GraphQL could offer a useful alternative.
