AWS App Mesh vs Tetrate Istio Subscription

AWS App Mesh is a managed service for visibility and traffic control between services. It uses the open source Envoy proxy to handle traffic into and out of service containers, and can change routes between services without application-code changes. Proxies balance client traffic and adjust endpoints using health checks and service registration. App Mesh provides metrics and logs for service hops, and can collect traces to help visualize service API calls. It works with AWS Fargate, Amazon ECS, Amazon EKS, Amazon EC2 and Kubernetes on EC2. Mutual TLS verifies service identities using certificates from AWS Certificate Manager Private Certificate Authority or a customer-managed certificate authority. Listed integrations include Amazon CloudWatch and AWS X-Ray, plus tools such as Datadog, HashiCorp and Sysdig. There is no additional charge for App Mesh itself, but proxy-consumed AWS resources are billed separately. AWS states support ends on September 30, 2026; after that, the console and App Mesh resources will no longer be accessible. API clients must support TLS 1.2; AWS recommends TLS 1.3.
