Exploring Canary Upgrades with Istio Ambient Mesh
Ambient Mesh leverages eBPF to reduce resource usage of Istio's data plane components. It eliminates the need for sidecar proxies because eBPF leverages the kernel network layer of worker nodes for mesh traffic management. The goal of this guide is to answer the following:
- What are the core components of Ambient Mesh?
- Which components are scoped to the kernel network layer
- Which components are scoped to the Kubernetes network layer?
- How does a canary upgrade of the Istio control plane work with Ambient Mesh?
