A LogicalDOC cluster is a group of independent computers that work together to increase the availability or the performance of the document management services. Clustered servers (called nodes) are connected by physical cables and software. If one of the cluster nodes fails, another node begins providing service (a process known as failover). Users experience a minimum of service interruptions.
Depending on what you want to achieve, you may opt for one of the supported architectures:
- Best Performance: useful for minimizing the response times in case of large installation with a lot of concurrent accesses
- High Availability (HA): when the document management is mission-critical, and you want to minimize the service interruptions
- Disaster Recovery (DR): a special case of High Availability where the focus is on the ability to restore operations after a disaster in an acceptable time frame
