Open-source service mesh providing traffic management and security for microservices across any Kubernetes cluster. Like having a universal traffic control system that works everywhere.
Multi-cloud applications use Istio to manage communication between microservices running across different cloud providers.
Istio is an open-source service mesh commonly run on Kubernetes. Cloud equivalents are managed or integrated service-mesh offerings: AWS App Mesh (Envoy-based mesh), Azure’s OSM add-on for AKS (OSM uses Envoy and supports Istio-like patterns), and Google Anthos Service Mesh (a managed Istio distribution). OCI does not have a direct, first-party managed service mesh equivalent; Istio is typically self-managed on OKE or via partners.
