The payment service's high latency triggered retry storms that overwhelmed dependent services. This incident exposed inconsistent reliability patterns across their 1,000+ microservices. The engineering team responded by implementing a custom service mesh using Envoy as the data plane, rejecting both Istio (too complex) and Linkerd2 (insufficient features). They built a minimal control plane focused on adaptive concurrency, outlier detection, and traffic metrics. Starting with an MVP using file-based configuration and canary deployments, they gradually evolved to include zone-aware routing, header-based routing, and distributed tracing. The system now handles 80M requests/second across 2,000 Kubernetes nodes, with automated onboarding reducing migration time from days to under an hour. 80 2. 2 [](/posts/kgateway-v2-1-is-released--ohfqye167 "Kgateway v2.1 is released!")

The release adds horizontal pod autoscaling, dynamic forward proxy support, enhanced session affinity options, and improved retry/timeout mechanisms. Notable additions include passive health checks with outlier detection and a new operations dashboard for Grafana. The Envoy-based AI Gateway is being deprecated in favor of agentgateway, which provides native support for AI workloads including MCP tools and inference tasks. 28 3. 3 [](/posts/announcing-istio-1-28-1-1qu1mzpyc "Announcing Istio 1.28.1") Article Istio · 45w Announcing Istio 1.28.1 Istio 1.28.1 is a patch release that addresses multiple bug fixes and security vulnerabilities.
