Use the information in this section to measure, understand, and manage the health of a deployed Domino application.
Domino runs in Kubernetes, which is an orchestration framework for containerized applications. In this model, the following are the distinct layers with their own relevant metrics:
- Domino application
This is the top layer, representing Domino application components running in containers that are deployed and managed by Kubernetes. The content in this Admin guide focuses on operations in this layer.
- Kubernetes cluster
This is the Kubernetes software-defined hardware abstraction and orchestration system that manages the deployment and lifecycle of Domino application components. Cluster operations are handled a layer below Domino, but do have to consider the Domino architecture and cluster requirements. For guidance about general cluster administration, see the official Kubernetes documentation.
- Host infrastructure
This is the bottom layer, that represents the virtual or physical host machines that are doing work as nodes in the Kubernetes cluster. IT owners of the infrastructure are responsible for operations in this layer, including management of compute and storage resources, as well as OS patching. Domino does not have any unique or unusual requirements in this layer.
