What Is a Data Plane Component?
The data plane is the layer that handles real user and application traffic, such as proxies forwarding requests or nodes running workloads. It executes the rules and placements that the control plane computes, but it does not make global decisions itself. Keeping the data plane simple and fast lets it scale horizontally for throughput.
Why it matters
Because the data plane sits in the request path, its latency and availability define what users experience. Isolating it from control logic means a control plane hiccup need not interrupt traffic already flowing.
