High Availability, Disaster Recovery, and Fault Tolerance
Production environments require increased uptime and business continuity, which depend on High Availability, Disaster Recovery, and Fault Tolerance capabilities explained in the following diagram.
Note:
Unlike high availability and fault tolerance, disaster recovery deals with catastrophic consequences that render entire IT infrastructures unavailable rather than single component failures. Since disaster recovery involves data and technology, its main objective is to recover data as well as get infrastructure components up and running within the shortest time frame after an unpredicted event.
Deployment Recommendations
The following cluster deployment options are recommended for the production and test environments:
