Nomirun Cluster is a cluster of Nomirun Hosts that are logically bound or deployed together. A good comparison to Nomirun Cluster is the same as Kuberentes Cluster / Namespace, where you can run multiple services or hosts.
Here is an example of a simple hierarchy when constructed in Nomirun:
IntegrationCluster is Nomirun cluster of Nomirun hosts,EmailingService, CrmService, AnalyticsService are Nomirun hosts (application that runs Nomirun modules),UserMailingModule, SalesforceModule, LegacyModule, DataAggregatorModule, YearlyReportsModule are Nomirun modules (NuGet packages).Please note that a cluster can also contain one host with one module. You cannot run the host alone like
nomirun host startand you always need to create the cluster and assign the host to it.
