Microsoft recently announced Open Service Mesh (OSM). OSM is a lightweight and extensible cloud native service mesh. OSM runs on Kubernetes and was built for that community. OSM is an open source project and Microsoft has already proposed to donate OSM to the Cloud Native Computing Foundation.
AWS already does very well in the cloud computing sphere, and they have now released an SDK for Go to add to the existing library of SDKs covering other languages. The official release adds new features to those in the developer preview stages and reduces dependency issues with Semantic Versioning.
