Infrastructure layer that manages service-to-service communication in microservices architectures. Like having a smart postal system specifically designed for application communication.
Large-scale applications use service mesh to automatically handle security, monitoring, and traffic management between microservices.
All provide service-mesh capabilities (traffic management, mTLS, observability) typically for Kubernetes and microservices. AWS App Mesh is AWS-managed control plane integrating with Envoy. Anthos Service Mesh is Google’s managed Istio-based offering. Azure’s Open Service Mesh is an AKS add-on based on OSM (an Envoy-based mesh). OCI does not have a single, dedicated first-party service-mesh product; service mesh is commonly implemented on OCI using Istio/Linkerd on OKE.
