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.

  • Standardized Kubernetes Custom Resource Definitions for service meshes
  • Traffic policy enforcement including identity and transport encryption
  • Traffic telemetry capturing metrics like error rates and latency
  • Traffic management for shifting service-to-service communication
  • Provider-agnostic service mesh API enabling interoperability

Backup & Disaster Recovery
Evaluate Veeam, Commvault, Rubrik, Cohesity, Dell PowerProtect, and Druva against your real RTO and RPO targets — with ransomware resilience, not backup windows, as the deciding criterion.
Cloud Cost Management & FinOps
Compare IBM Apptio Cloudability, VMware Tanzu CloudHealth (Broadcom), Flexera One, Harness, Finout, Zesty, and Vantage on the question this category actually turns on — not whether a dashboard is pretty, but whether shared-cost allocation is accurate, committed-use buying is optimized, and engineering acts on the recommendations.
Cloud Infrastructure & IaaS
Compare AWS, Microsoft Azure, Google Cloud, Oracle Cloud Infrastructure, IBM Cloud, Alibaba Cloud, and DigitalOcean on the one thing the pricing calculator hides — egress, support-tier costs, committed-use discounts, and lock-in — not the on-demand compute rate the demo shows you.
