Although " use App Mesh for ingress routing" is listed as on the post-GA feature roadmap, the App Mesh documentation currently recommends using AWS Elastic Load Balancing to handle all "north-south" internet traffic and traffic from clients that are not within the organisation's trust boundary. Routes: A route is associated with a virtual router, and it directs traffic that matches a service name prefix to one or more virtual nodes.ĪWS App Mesh Components (image taken from App Mesh docs)Īpp Mesh is currently targeting the use case of service-to-service "east-west" traffic control and observation.Virtual routers: The virtual router handles traffic for one or more service names within a service mesh.Envoy proxy and router manager: The Envoy proxy and its router manager container images configure the microservice task group to use the App Mesh service mesh traffic rules that have been configured for virtual routers and virtual nodes.Virtual nodes: A virtual node acts as a logical pointer to a particular "task group", such as an ECS service or a Kubernetes deployment.Service mesh: An instance of a " service mesh" (in AWS parlance) is a logical boundary for network traffic between the services that reside within it.The Envoy "sidecar" containers enable App Mesh to intercept and manage all communication from the associated service, and export metrics, logs, and traces to the endpoints specified in the Envoy bootstrap configuration provided.ĪWS App Mesh is made up of the following components: Wth Kubernetes an Envoy proxy image must be added to the Kubernetes PodSpec. However, some of this functionality is scheduled for the GA release but is not currently implemented within App Mesh.įor deployment of App Mesh on ECS an Envoy proxy container image must be added to the associated task definition. Leveraging functionality provided by Envoy, traffic can also be shadowed to alternate environments for further troubleshooting, and faults can be injected for running chaos experiments. App Mesh can also enforce access controls, quotas, and limits on service clients. App Mesh can currently be used with Amazon Elastic Container Service (ECS), Amazon Elastic Container Service for Kubernetes (EKS), and Kubernetes on EC2.ĪWS App Mesh provides APIs (exposed via a CLI and SDK) that allow the specification of fine-grained traffic routing between applications based on service versions, for example, allowing a canary release or A/B deployment. App Mesh is effectively an AWS-specific hosted control plane for Envoy, an open source service mesh data plane proxy. The provisioning state of the application.Amazon has released AWS App Mesh, a service mesh that allows developers to standardise how microservices communicate, implement rules for communications between microservices, and capture metrics, logs, and traces directly into AWS services and third-party tools.
