What is the primary goal of the Service Mesh Interface (SMI)?

• A. To enforce end-to-end encryption for service traffic
• B. To store telemetry data for service meshes
• C. To offer a common, interoperable interface for various Service Mesh solutions
• D. To manage container orchestration

Answer: (C)

SMI is about providing a single, common interface that multiple service meshes can implement, so you can manage traffic, policies, and observability in a mesh-agnostic way. This standardization lets tools and workflows work with Istio, Linkerd, Consul, and other meshes without needing mesh-specific configurations. The interface defines a minimal set of resources (CRDs) that describe how traffic should be split, what policies apply, and how services are identified, enabling consistent rules across different mesh implementations. It isn’t about enforcing encryption, storing telemetry, or handling container orchestration—those are handled by the individual meshes and the cluster platform. By promoting interoperability, SMI reduces vendor lock-in and makes it easier to integrate with monitoring and automation tooling.
