 Service mesh technology operates at the network communication level. That is, service mesh components capture or intercept traffic to and from microservices, either modifying requests, redirecting them, or creating new requests to other services.

 The *data plane* is a set of intelligent proxies, running alongside application containers in a pod, that intercept and control all inbound and outbound network communication between microservices in the service mesh.
 The data plane is implemented in such a way that it intercepts all inbound (ingress) and outbound (egress) network traffic. The Istio data plane is composed of Envoy containers running along side application containers in a pod. The Envoy container acts as a proxy, controlling all network communication into and out of the pod.

 You use an `ExportedServiceSet` resource to declare the services from one mesh that you are making available to another peer in the federated mesh. You must explicitly declare each service to be shared with a peer.

 You use an `ImportedServiceSet` resource to select services for import. Only services exported by a mesh peer and explicitly imported are available to the mesh. Services that you do not explicitly import are not made available within the mesh.

 You declare the federation between two meshes by creating a `ServiceMeshPeer` resource. The `ServiceMeshPeer` resource defines the federation between two meshes, and you use it to configure discovery for the peer mesh, access to the peer mesh, and certificates used to validate the other mesh’s clients.

 Meshes are federated on a one-to-one basis, so each pair of peers requires a pair of `ServiceMeshPeer` resources specifying the federation connection to the other service mesh. For example, federating two meshes named `red` and `green` would require two `ServiceMeshPeer` files.
 
 . On red-mesh-system, create a `ServiceMeshPeer` for the green mesh.
