Episode 28 — API Gateways & Proxies for AI

This episode focuses on API gateways and proxies, emphasizing their role as critical control points for AI applications. An API gateway manages traffic to model endpoints, providing authentication, authorization, rate limiting, and policy enforcement. Proxies filter and shape requests or responses, enabling organizations to apply additional layers of validation. For certification purposes, learners must define these components and explain how they mitigate risks such as abuse, data leakage, and unauthorized access. Exam questions frequently address why gateways and proxies are integral to defense-in-depth for AI workloads.

In practice, this episode explores scenarios where gateways prevent denial-of-wallet attacks by enforcing quotas, or where proxies filter unsafe model outputs before exposing them to end users. Best practices include enforcing TLS encryption, integrating with identity providers, and using layered filters for both inputs and outputs. Troubleshooting considerations highlight risks when proxies are misconfigured, creating bypass opportunities or introducing latency bottlenecks. For learners, the key takeaway is that gateways and proxies serve as chokepoints where policy, monitoring, and defense converge to protect sensitive AI systems from evolving threats.
