Service Mesh Interface (SMI)
Open SourceFundedStandardized service mesh interface for Kubernetes cloud networking
About Service Mesh Interface (SMI)
Service Mesh Interface (SMI) is an open-source specification designed to provide a standardized interface for service meshes operating within Kubernetes environments. It defines a set of Kubernetes Custom Resource Definitions (CRDs) and Extension API Servers that enable consistent management of service mesh capabilities such as traffic policy, telemetry, and traffic management. This abstraction allows enterprises to adopt service mesh technologies without being locked into a specific vendor implementation, promoting flexibility and interoperability across cloud-native infrastructures.
Targeted at enterprise IT organizations managing complex microservices architectures on Kubernetes, SMI simplifies the integration and operation of service meshes by offering a common, provider-agnostic API. This enables CIOs and technology leaders to implement service mesh features like identity-based traffic policies, transport encryption, and traffic shifting with standardized tooling and processes. By fostering an ecosystem that supports innovation and evolution of service mesh capabilities, SMI helps enterprises optimize cloud networking and security while reducing operational complexity.
