Concepts

The Istio Developer Portal provides two parallel sets of features which can be used independently, but function best when they are combined.

The first is Routing: by leveraging the Istio Gateway functionality, the Developer Portal can automatically expose service APIs on behalf of users without the need to directly interact with the underlying infrastructure (Istio / Kubernetes). By enabling Routing through the Developer Portal, users can apply authorization and rate limiting policies to individual APIs without having to reason through complex and fragile Istio configurations.

The second is the Portal Web UI. The Portal Web UI provides a customizable web application which enables developer onboarding for APIs: - Browse a catalog of published APIs including static and generated documentation. - Request API Keys for accessing protected APIs. - Visualize and interact with published API resources.
