ESM for Fusion is a container-based application. To deploy and manage ESM for 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 ESM for Fusion either on a single-node or multi-node cluster setup.
If you already have the ArcSight Platform installed, you can deploy ESM for Fusion to the same cluster. Reusing existing clusters allows you to reduce costs and system management effort, when compared to deploying ESM for Fusion in a new cluster.
