Cloud / Istio Interview questions
How Istio works?
Istio uses a proxy to intercept all your network traffic, allowing a broad set of application-aware features based on configuration you set.
The control plane takes your desired configuration, and its view of the services, and dynamically programs the proxy servers, updating them as the rules or the environment changes. The data plane is the communication between services. Without a service mesh, the network doesn't understand the traffic being sent over, and can't make any decisions based on what type of traffic it is, or who it is from or to.
Istio supports two data plane modes:
- sidecar mode, which deploys an Envoy proxy along with each pod that you start in your cluster, or running alongside services running on VMs.
- ambient mode, which uses a per-node Layer 4 proxy, and optionally a per-namespace Envoy proxy for Layer 7 features.
