The Service Mesh Interface (SMI) is a specification for service meshes, with a focus on those that run on Kubernetes. It defines a common standard that can be implemented by a variety of providers. This allows for both standardization for end-users and innovation by providers of Service Mesh Technology. SMI enables flexibility and interoperability, and covers the most common service mesh capabilities.
