  • Service meshes transformed how we secure microservices, but the original sidecar model introduced its own complexity and vulnerabilities. Now, Istio’s ambient mesh is rethinking the security foundation of service connectivity. In this video, 📽️ https://lnkd.in/gbW_iRfv we explore how ambient mesh strengthens zero-trust networking by addressing the limitations of sidecar-based workloads: ✔️ Reduced attack surface: No in-pod proxies mean fewer exposure points and fewer vulnerabilities. ✔️ Isolated credentials: Secrets and certificates are no longer stored in application pods, preventing credential leaks. ✔️ Improved mTLS enforcement: Ambient enforces encryption and authorization at the node level with hardened ztunnels. ✔️ Operational simplicity: Upgrades and maintenance no longer require touching every workload. ✔️ Performance-driven security: Lightweight design improves resilience under heavy load and reduces the risk of degraded policy enforcement. We’ll break down how ambient mesh retains all the core security benefits of sidecar mode — identity, mTLS, and zero trust — while simplifying operations and improving protection against modern threats. #ServiceMesh #AmbientMesh #Istio #ZeroTrust #CloudNative #Kubernetes #Soloio

    🔐 Istio Ambient Mesh: A Security Upgrade? Sidecar-based service meshes brought mTLS and workload identity—but also introduced new risks. In this blog, Eitan Suez dives into how ambient mesh helps close security gaps by: ✅ Removing sidecars from app pods ✅ Isolating credentials ✅ Simplifying traffic & policy enforcement A great read for teams thinking about modernizing their mesh architecture. 🔗 https://lnkd.in/gjCnmMvT #Istio #AmbientMesh #ServiceMesh #Security #CloudNative #ZeroTrust #DevSecOps

    MCP is emerging as a powerful pattern for LLM-based systems — but how do you support it in today’s API infrastructure? 👉 In this blog post, Christian Posta takes a look at doing this with the Apigee API Gateway — what’s possible, what’s challenging, and why a purpose-built MCP gateway (like @agentgateway) might be a better fit for real-world use. We’re sharing our learnings to spark conversation — if you’ve been experimenting in this space, we’d love to hear what’s worked for you. 🧠 Read all about it here: https://lnkd.in/gKir39-A #MCP #LLMAgents #AgentGateway #Apigee #LLMInfra #AICommunity #OpenSource #DevCommunity #APIManagement

  • 🚫 Sidecars or no sidecars? That is the question! Thinking about moving from sidecar-based Istio to sidecarless Ambient Mesh? Or maybe you're just trying to make sense of the differences? We’ve got you covered. Check out our new datasheet to see how Gloo Mesh helps simplify service mesh operations, reduce overhead, and support both models — so you can scale and secure your apps your way. 👉 https://lnkd.in/gk9GkEV3 #ServiceMesh #Istio #AmbientMesh #GlooMesh #Kubernetes #DevOps

    I’ve been working hard with my co-author Christian Posta on an AI agents in Kubernetes book 📘🤖 that we’ll be sharing at KubeCon NA in Atlanta! 🇺🇸✨ After weighing our publishing options ⚖️, we decided to go the self-publishing route. Between us, we’ve written several books 📚, but with this space evolving so quickly ⚡ we wanted the flexibility to keep it updated with new insights on AI agents in Kubernetes for each upcoming KubeCon. In the book, we introduce AI agents and MCP servers, showing how kagent, kmcp, and agentgateway with kgateway fit together to provide production-ready foundations for enterprise AI. We also walk through a hands-on example so you can get the AIRE agent 🚀 running in your own Kubernetes cluster ☸️. The best part: these are modular building blocks 🧩—you can run your own agent without kagent while still using agentgateway, run your own MCP server without kmcp while using agentgateway, and more. Can’t wait to share it with you all in Atlanta! 🙌🎉
