The most efficient deployment of XPLG is a cluster one. The cluster may be deployed as multiple processes on the same machine at described in this article, or on multiple machines.
The clustering mechanism of XPLG manages all its tasks automatically and dynamically based on the available cluster processes.
A clustered deployment has some key advantages:
- Scalability - by adding additional processes, support any required volume.
- Users activity vs. back end processing - a separation between the users activity and the backend processes of data in order to maintain high quality of service.
- Multiple points of failure - all cluster nodes may function as alerting and processing nodes in cases of failures to avoid loss of data / loss of service.
- Fast Disaster Recovery (DR) - XpoLog has automated procedures to maintain configuration backups that may be easily used to restore a system.
- Fault tolerance - During a cluster node failure or following an entire cluster failure, XpoLog recovers immediately and accurately to complete undigested data, reports and monitors.
Single Machine Cluster
A basic cluster of XpoLog runs at least 2 processes running on the same machine (commonly, this is suitable for small-mid environments as an initial clustered deployment).
The following diagram presents a clustered environment with multiple user interface nodes and data processing nodes.
 Integration to Active Directory / SSO for authentication and authorization
 UI Process - a process dedicated to serve users activity
 Master/Processor process - the cluster orchestrator and processing engine
 Storage - a file system based storage accessible by all cluster nodes
