As illustrated in the High-level Che architecture article, Eclipse Che components are:

  • A central workspace controller: an always running service that manages users workspaces

  • Users workspaces: container-based IDEs that the controller stops when the user stops coding

Both the Che central controller and user workspaces consist of a set of containers. Those containers contribute to the resources consumption in terms of CPU and RAM limits and requests. For a detailed explanation of how Kubernetes manages container-resource requests and limits, see Kubernetes documentation.
