Ambient Mesh

aid: ambient-mesh
name: Ambient Mesh
description: Ambient Mesh is a sidecar-less service mesh architecture built on Istio that simplifies microservices communication,
  enhances zero-trust security, and improves observability without requiring sidecar proxy injection. It uses a shared per-node
  proxy (ztunnel) for zero-trust security and optional waypoint proxies for advanced Layer 7 policies, enabling seamless migration
  from sidecar-based meshes with zero downtime.

  description: Ambient Mesh provides a sidecar-less service mesh via the Kubernetes Gateway API and Istio ambient mode. It
    exposes configuration APIs for traffic management, security policies, resilience settings, and observability through standard
    Kubernetes CRDs including HTTPRoute, Gateway, AuthorizationPolicy, and WaypointProxy resources.
