In a failover system, the servers are combined into a logical structure - the cluster. The Axxon Next server services (nodes) are controlled by supervisors and can run on any of the cluster computers.
The C-Werk Failover system has two types of configuration.
- The basic configuration allows system supervisors to permit launching C-Werk servers (nodes) on any Servers within the system.
- In the configuration with the specified backup Server, a node from the primary Server can be migrated only to the backup Server. After the primary Server is back online, the node is returned.
Node migration is automatic and takes no more than one minute.

- Server -a computer with Failover Server and Client configuration of Axxon Next C-Werk installed.
- Node- an instance of the Server services. A Server can have multiple nodes running.
- Cluster- logical grouping of Servers that allows migration of clusters between them. A cluster may encompass nodes from different Axxon C-Werk domains.
- Supervisor- the service that monitors the status of nodes and their migration.
