Your new AI gateway stack is humming along until you realize every service, model, and endpoint needs consistent access control and logging. That is where Kong Vertex AI becomes the grown-up in the room. It brings the power of Google Cloud’s Vertex AI to Kong’s API management layer, turning model calls into first-class, auditable API transactions.
Kong excels at routing, rate limiting, and policy enforcement. Vertex AI handles the real work of training and serving models at scale. Together they bridge a gap few teams realize they have: how do you safely expose machine learning endpoints to multiple applications without reinventing identity, quotas, and governance each time?
Think of the integration like a traffic cop with a PhD in compliance. Kong authenticates incoming requests using OIDC or your identity provider of choice—Okta, Azure AD, or AWS IAM. Once verified, the call passes through to Vertex AI’s custom endpoints. Kong decorates that request with context about who called, from where, and under which scope. Vertex AI performs inference and returns results, while Kong collects structured metrics for monitoring and billing. Simple paths, tight gates.
If you are wiring this up, focus on three control points:
- Authentication via JWT claims or OIDC tokens.
- Consistent header propagation so Vertex AI understands the client context.
- Logging and metrics export to your preferred collector, whether that is Cloud Logging or Prometheus.
The setup is lightweight once you see the shape of the flow. API managers often struggle with misaligned IAM roles or secret sprawl. Here Kong absorbs most of that pain. Tokens expire cleanly. RBAC rules stay readable. And your data science team no longer needs to memorize IAM policies just to call their own model.
