  • Enhanced disaster recovery procedure of applications in a cloud environment
    Patent number: 11048598
    Abstract: A disaster recovery data store may contain an operator-defined parallel account failover value. A disaster recovery service platform may establish a primary region as an active region and determine that a potential disaster has occurred in connection with the primary region. A warm-up process may be initiated causing a pool of virtual machines to begin execution at a secondary region. The platform may then determine that an actual disaster has occurred in connection with the primary region and simultaneously execute disaster recovery failover procedures from the primary region to the secondary region for multiple accounts in parallel based on the operator-defined parallel account failover value. Before all failover procedures are complete, the platform may transmit at least one intermediate failover report. After all failover procedures are complete, the platform may transmit a final failover report and establish the secondary region as the active region using the pool of virtual machines.
