APIs and Inference Gateways

This lesson introduces APIs and inference gateways, the technologies that enable applications to interact with AI models in production environments. Learners explore how APIs expose AI capabilities to users and systems while gateways provide security, scalability, observability, and traffic management. The lesson examines concepts such as rate limiting, throttling, batching, cold starts, authentication, caching, and monitoring. Students will gain practical knowledge of how organizations operate AI services reliably, securely, and efficiently at enterprise scale.
