Fusion is a container-based application. To deploy and manage Fusion, you must first install the Container Deployment Foundation (CDF), which is a container and management module built on Kubernetes and Docker containers. You can deploy the components for Fusion either on a single-node or multi-node cluster setup.
If you already have an existing cluster for ArcSight Transformation Hub or ArcSight Investigate, you can deploy Fusion to the same cluster. Reusing existing clusters allows you to reduce costs and system management effort, when compared to deploying Fusion in a new cluster.
