What is a key feature of a container network?

Proxying REST requests is typically handled by API gateways or service meshes, not the fundamental container network itself.

A fundamental requirement for container orchestration systems like Kubernetes is that all containers can communicate with each other, regardless of which physical host they are running on. Container networking provides a consistent network fabric that spans across nodes, facilitating this essential inter-host container communication for distributed applications.

While containers on the same host can communicate, a key feature of a distributed container network is extending this capability beyond a single host.

Caching remote disk access is related to storage performance and is not a primary function of container networking.
