In Service Fabric, a cluster is a network-connected set of virtual or physical machines into which your Microservices are deployed and managed. Clusters can scale to thousands of machines. In traditional data centers, the most deployed clusters are the failover cluster and the load balancing cluster. However, quite unique to the Service Fabric cluster is the Service Fabric cluster resource manager. The Service Fabric cluster resource manager is responsible for deploying the Microservices across the nodes, taking care of the node capacity, fault tolerance, and sufficient replication. Since multiple Microservices can be deployed on a node, the Service Fabric cluster resource manager ensures that there is proper utilization of the compute resources.
