Open Source Summit Europe 2024

Istio Ambient introduces a sidecar-less paradigm, aiming to simplify workload operations. Lin, a founding member of Istio, will guide you through the progressive application delivery process without sidecars, leveraging Argo Rollout while maintaining security, traffic control, and resilience with ambient service mesh. Lin will demonstrate the use of ArgoCD and Kubernetes Gateway resources (Gateway and HTTPRoute) to systematically increment weights, automatically directing traffic to a new application version. Throughout this process, she'll showcase monitoring using Prometheus metrics provided by Istio to ensure optimal performance. If defined success criteria aren't met, Argo Rollouts automatically triggers a rollback. Lin will illustrate the power of ArgoCD rollout with sidecar-less applications in Istio through a live demo. Additionally, she will delve into cost-saving strategies during rollout and highlight the distinctions between sidecar and sidecar-less application rollouts.
