How ingress works
Kuma provides two features to manage ingress traffic, also known as north/south traffic. Both take advantage of a piece of infrastructure called a gateway proxy, that sits between external clients and your services in the mesh.
- Delegated gateway: allows users to use any existing gateway proxy, like Kong.
- Builtin gateway: configures instances of Envoy to act as a gateway.
Gateways exist within a Mesh.
If you have multiple Meshes, each Mesh requires its own gateway. You can easily connect your Meshes together using cross-mesh gateways.
The below visualization shows the difference between delegated and builtin gateways. The blue lines represent traffic not managed by Kuma.
