Amazon EKS is one of the most popular ways to deploy microservices on Kubernetes, but running large-scale production workloads on EKS creates new complications: 

• Security concerns as the microservice components are distributed across one or more clusters or regions
• Reliability concerns as individual services, clusters, and even entire regions can fail
• Traffic Management concerns to address scalability, security, rate limiting and rolling-upgrade risks
• Operational concerns with the additional complexity of the Kubernetes stack and the higher risk of configuration error

Service Mesh is a dedicated infrastructure layer on top of microservices that provides service discovery, security, authentication and observability across the microservice components. Istio and Envoy are the open source standards for the service mesh control and data plane, but Istio and Envoy are only partial solutions because they add new operational complexities for platform teams running Amazon EKS.

Tetrate Service Express provides service mesh automation for platform teams on top of Istio and Envoy. It handles the installation and configuration of open source components on Amazon EKS, integrates with AWS services and provides a management console for platform operators to configure the service mesh for security, resilience and observability faster.

Tetrate Service Express is designed specifically for teams that need to quickly prove the technical and business benefits of a service mesh for Amazon EKS without having to master the complexities of Istio and Envoy or creating technical debt when managing open source software.
