System and method for scaling resources of a secondary network for disaster recovery

A non-transitory computer-readable storage medium containing program instructions for scaling resources of a secondary network for disaster recovery, wherein execution of the program instructions by one or more processors of a computer system causes the one or more processors to perform steps comprising:

• in response to a disaster recovery event at a primary network, transmitting a disaster recovery notification to a secondary resource manager of the secondary network from a primary resource manager of the primary network, the disaster recovery notification including latest resource demands of workloads on the primary network;
• generating a scale-up recommendation for additional resources to the secondary network by the secondary resource manager based on the latest resource demands of the workloads on the primary network included in the disaster recovery notification during a recommendation scaling mode, including switching a mode of operation of the secondary resource manager from a statistical-based scaling mode to a the recommendation scaling mode, wherein the statistical-based scaling mode uses a fixed incremental number of host computers for a scale-up operation for each scale-up recommendation;
• executing a scale-up operation for the additional resources to the secondary network based on the scale-up recommendation from the secondary resource manager;
• and operating the secondary network with the additional resources to run the workloads on the secondary network.

A system comprising:

• memory;
• and at least one processor configured to:
• in response to a disaster recovery event at a primary network of the system, transmit a disaster recovery notification to a secondary resource manager of a secondary network of the system from a primary resource manager of the primary network, the disaster recovery notification including latest resource demands of workloads on the primary network;
• generate a scale-up recommendation for additional resources to the secondary network by the secondary resource manager based on the latest resource demands of the workloads on the primary network included in the disaster recovery notification during a recommendation scaling mode;
• execute a scale-up operation for the additional resources to the secondary network based on the scale-up recommendation from the secondary resource manager;
• and operate the secondary network with the additional resources to run the workloads on the secondary network, wherein the at least one processor is configured to switch a mode of operation of the secondary resource manager from a statistical-based scaling mode to a the recommendation scaling mode, wherein the statistical-based scaling mode uses a fixed incremental number of host computers for a scale-up operation for each scale-up recommendation.
