After careful consideration, we have made the decision to discontinue support for AWS App Mesh, effective September 30th, 2026. Until this date, existing AWS App Mesh customers will be able to use the service as normal, including creating new resources and onboarding new accounts via the AWS CLI and AWS CloudFormation. Additionally, AWS will continue to provide critical security and availability updates to AWS App Mesh during this period. However, starting from September 24th, 2024, new customers will be unable to onboard to AWS App Mesh.

At re:Invent 2022, AWS introduced Amazon ECS Service Connect, a new way to connect microservices within Amazon Elastic Container Service (Amazon ECS). This post dives deep into Service Connect and discusses strategies for migrating from AWS App Mesh to Service Connect. Service Connect improves the reliability of containerized microservices through built-in health checks, outlier detection, and retry mechanisms. It also enhances observability by sending application-level networking metrics to Amazon CloudWatch. By using a managed networking data plane, Service Connect eliminates the undifferentiated heavy lifting associated with managing sidecar proxies.

Service meshes implement routing rules, add security layers, and provide observability through abstraction layers. Before undertaking a migration, it is crucial to understand the abstraction layers of Service Connect and compare them to those of App Mesh. This section shows these abstractions using a multi-tiered application deployed on Amazon ECS.
