What does SMI enable across multiple service mesh implementations?

• A. A common interface for interoperability across multiple Service Mesh solutions
• B. A new data plane protocol
• C. A storage format for metrics
• D. A container runtime

Answer: (A)

SMI provides a common, mesh-agnostic interface that standardizes how you describe traffic routing, policies, and observability across different service mesh implementations. By defining a stable set of APIs and CRDs, tools and operators can manage and observe services regardless of whether the underlying mesh is Istio, Linkerd, Consul, or another solution. This interoperability is what lets you apply consistent traffic policies or collect metrics across multiple meshes without tying you to a single vendor’s API. It’s not about introducing a new data plane protocol, a storage format for metrics, or a container runtime. Those areas remain specific to each mesh and runtime, while SMI sits on top to unify interaction surfaces.
