API gateways solve a universal problem: every API you expose needs authentication, rate limiting, documentation, and analytics, but implementing these in every service creates scattered logic and inconsistent policies. This video breaks down what API gateways actually are, when they're essential, and when they're overkill. You'll learn how gateways fit into different architectures—from traditional VMs to Kubernetes to serverless—and why they're critical for north-south traffic but completely unnecessary for service-to-service communication.

The video explores Zuplo as a practical example, walking through both their API Management gateway for REST APIs and their AI Gateway for LLM traffic. You'll see how to import OpenAPI schemas, attach policies like rate limiting, and integrate with GitOps workflows. For AI applications, the gateway provides centralized cost tracking, provider failover, and unified API keys across your organization. The honest review covers both strengths (excellent developer experience, edge deployment, built-in monetization) and limitations (schema duplication, TypeScript-only custom logic, no self-hosting option) to help you decide if it's the right fit for your needs.

API gateways centralize cross-cutting concerns like authentication, rate limiting, and analytics for external-facing APIs. They're essential for serverless architectures and useful for traditional deployments, but unnecessary for internal service-to-service communication in Kubernetes. The video demonstrates Zuplo, a managed API gateway with edge deployment, developer portals, and specialized AI gateway features for managing LLM access. Key takeaway: use API gateways for north-south traffic only, not east-west internal communication.
