Istio

Excited about the agentgateway integration with Istio ambient, now merged into kgateway, where Istio’s CA can manage agentgateway’s certificates 🎉 This is a critical step toward an agentic mesh with Istio and agentgateway. Thanks John Howard Nina Polshakova and team!

Interesting discussion in Istio working group meeting today about agentgateway integration in Istio 🎉 Are we ready for Agentic AI mesh?

One of my favorite #Kubecon trends this year was seeing multiple Cloud Native Networking projects begin to standardize their mTLS implementations on Istio's #rust based ztunnel. mTLS is such a game changing security technology, and I'm thrilled to see Cilium and Calico leveraging the power of Istio to bring security best practices to a wider audience! Of course, none of this would be possible without a robust open source community around these projects, thanks to the Cloud Native Computing Foundation (CNCF)! https://lnkd.in/gYQaypWR

Here's our story of migrating Careem to Istio using Gateway API and Flagger — presented at KubeCon + CloudNativeCon North America 2025! 🎙️ The Challenge: Careem handles close to 5 billion Kubernetes-based service requests daily. As our platform evolved, we began outgrowing the operational and extensibility constraints of our existing service mesh. Our Approach: We executed an in-place, zero-downtime migration to Istio within the same cluster — without increasing infrastructure costs or rewriting most service configurations. The key enabler was our early adoption of the Kubernetes Gateway API (GAMMA initiative). By building on vendor-neutral, Kubernetes-native APIs, we achieved a "define once, swap many times" model that allowed us to reuse the majority of our existing configurations. To validate changes safely in production, we integrated Flagger for metrics-driven canary rollouts and gradual traffic shifting. 🎥 Watch the full talk: https://lnkd.in/dY9xXyX4 A major milestone for our Traffic Engineering team as we continue strengthening reliability across our platform 💚 #KubeCon #KubeConNA #ServiceMesh #Istio #Envoy #GatewayAPI #Flagger #CloudNative Cloud Native Computing Foundation (CNCF) | Istio | Envoy |

Istio at KubeCon North America 2025 — Recap & Highlights Excited to share our latest blog covering everything Istio at KubeCon + CloudNativeCon North America by Cloud Native Computing Foundation (CNCF) — from Istio Day highlights to deep-dive talks, industry adoption stories, and the growing ecosystem around ambient mode, multi-cluster networking, and mesh-powered platforms. This post brings together key moments, themes, and insights from the event - along with YouTube links to all the sessions so you can explore them at your own pace. Read the full recap here: https://lnkd.in/e-CRsARR A huge thank you to all the speakers, contributors, end users, and community members who continue to push Istio and the service mesh ecosystem forward. Your energy at KubeCon was incredible — and it’s exciting to see how fast the technology continues to evolve. If you're working with service meshes, platform engineering, or cloud-native networking, you'll find this roundup useful. Would love to hear your thoughts! #Istio #ServiceMesh #KubeCon #CloudNative

One of the most special moments for me on Day 2 of #KubeCon + #CloudNativeCon North America 2025 was seeing two incredible people I had the privilege of nominating, walk on stage to receive their Cloud Native Computing Foundation (CNCF) Community Awards. John Howard received the Top Committer Award, recognizing his unmatched impact across the CNCF ecosystem — with over 15,000 contributions across 130 CNCF repositories. Beyond his technical leadership, John quietly ensures CI pipelines run smoothly, oversees release management while mentoring new release leads, reviews RFCs, triages GitHub issues, and answers countless community questions across Slack and mailing lists. He not only drives the technical direction of Istio and related projects but also mentors and supports hundreds of contributors, helping to build a thriving, sustainable open-source community. (On a personal note — John was one of the first people who helped me when I started my own Istio journey) Daniel Hawton received the Chop Wood Carry Water Award, honoring his tireless behind-the-scenes dedication that keeps the Istio project strong and secure. Since joining in 2022, he’s served as release manager for multiple versions, co-led the Product Security Working Group, maintained documentation and testing infrastructure, and mentored new contributors — always showing up with humility, consistency, and heart. It was truly rewarding to see both of them recognized for their incredible work and spirit of collaboration. Congratulations, John and Daniel — you make all of us in the Istio community proud! 💙 Congratulations to all other winners too 🙂

Standard Istio vs Ambient Mesh comes down to: ✅ No more sidecars in Ambient ✅ Splitting L4 and L7 vs having it in the sidecar In this video, I break down the why behind Ambient Mesh and the full installation process. https://buff.ly/FqGGRCf #kubernetes #devops #platformengineering
