We should also mention two new service meshes offered by AWS and Microsoft, which are outside the scope of this book but deserve to be mentioned here:
- App Mesh: In November 2018, AWS announced its own service mesh called App Mesh that went General Availability (GA) on March 2019. AWS manages the App Mesh control plane and is not open source. App Mesh uses an open source Envoy sidecar proxy for its data plane and is free to use on AWS.
- Azure Service Fabric Mesh: Microsoft announced its service mesh on September 2018. It is a fully managed service that's used to deploy microservices applications for developers by abstracting the platform layer. It uses an open source Envoy sidecar proxy for service discovery and routing.
