This article explains Istio Ambient Mode, a sidecarless service mesh designed to reduce operational complexity in Kubernetes environments. It highlights how this approach streamlines networking, security, and observability while improving efficiency and security through mutual TLS (mTLS) without requiring changes to application code.

Organizations are increasingly adopting IPv6 for their Amazon EKS deployments to address IPv4 limitations such as address depletion and security vulnerabilities. The article provides a step-by-step guide for integrating IPv6 EKS clusters into existing Istio Service Mesh environments, allowing for seamless communication between IPv4 and IPv6 workloads. It also outlines deployment models and configurations to facilitate this transition effectively.
