summary
Istio now ships ambient mode GA since November that runs proxies only where needed while continuing to support sidecars, and it installs with a one-command install plus a namespace/pod label flow that requires no app restarts. Security uses FIPS‑grade encryption, frequently rotated PKI-backed certificates that integrate with external PKI, and identity-based policy enforcement. Features include L4/L7 load balancing, path routing, ingress/egress, traffic mirroring/retries/fault injection, multicluster discovery, and built‑in telemetry. The project reports 25 companies contributing >100 PRs in the last two years.
