Konnect Architecture

The Kong Konnect platform provides a cloud control plane (CP), which manages all service configurations. It propagates those configurations to all runtime nodes, which use in-memory storage. These nodes can be installed anywhere, on-premise or in the cloud.

Runtime instances, acting as data planes, listen for traffic on the proxy port 443 by default. The Konnect data plane evaluates incoming client API requests and routes them to the appropriate backend APIs. While routing requests and providing responses, policies can be applied with plugins as necessary.

For example, before routing a request, the client might be required to authenticate. This delivers several benefits, including:

• The service doesn’t need its own authentication logic since the data plane is handling authentication.
• The service only receives valid requests and therefore cycles are not wasted processing invalid requests.
• All requests are logged for central visibility of traffic.
