Flomesh open source service mesh osm-edge is based on an implementation of the SMI (Service Mesh Interface) standard. SMI defines specifications for traffic identification, access control, telemetry, and management. In the previous article Kubernetes: Multi-cluster communication with Flomesh Service Mesh we covered the background, motivations, and goals of Kubernetes multi-cluster and part 2 Kubernetes: Multi-cluster communication with Flomesh Service Mesh (Demo) we demonstrated a detailed demo of how to use FSM in a multi-cluster environment and how to schedule policies for traffics.
Before we start, let's review the SMI Access Control Specification. There are two forms of traffic policies in osm-edge: Permissive Mode and Traffic Policy Mode. The former allows services in the mesh to access each other, while the latter requires the provision of the appropriate traffic policy to be accessible.
