System and method for dynamically adjusting recovery time objective in a virtual computing system

A system comprising:

• a migration controller comprising:
• a memory having computer-readable instructions stored thereon;
• and a processor that executes the computer-readable instructions to:
• determine a first subset of a plurality of virtual machines (VMs) and a different second subset of the plurality of VMs based on a recovery plan, wherein the first subset to be migrated based on an asynchronous mode of replication and the second subset to be replicated based on a synchronous mode of replication, and wherein the first subset includes a first VM and a third VM and the second subset includes a second VM;
• and
• migrate the first VM of the first subset of VMs from a source site to a target site in a virtual computing system based on the asynchronous mode of replication, wherein migrating the first VM includes replicating the first VM from the source site to the target site, powering off the first VM at the source site, and powering on the first VM at the target site;
• replicate data of the second VM of the second subset of VMs from the source site to the target site based on the synchronous mode of replication, wherein the replication of the data of the second VM is performed in parallel with the migration of the first VM;
• subsequent to the parallel migrating and replication of at least one VM of the first subset and the second subset, determine whether a resource consumption of the virtual computing system is less than or equal to a predetermined threshold;
• based on the resource consumption being less than or equal to the predetermined threshold, modify the first subset and the second subset to move the third VM from the first subset to the second subset and migrate the third VM from the source site to the target site in the virtual computing system based on the synchronous mode of replication.

A non-transitory computer-readable media comprising computer-readable instructions stored thereon that when executed by a processor in a virtual computing system cause the processor to:

• determine a first subset of a plurality of virtual machines (VMs) and a different second subset of the plurality of VMs based on a recovery plan, wherein the first subset to be migrated based on an asynchronous mode of replication and the second subset to be replicated based on a synchronous mode of replication, and wherein the first subset includes a first VM and a third VM and the second subset includes a second VM;
• migrate the first VM of the first subset of VMs from a source site to a target site in a virtual computing system based on the asynchronous mode of replication, wherein migrating the first VM includes replicating the first VM from the source site to the target site, powering off the first VM at the source site, and powering on the first VM at the target site;
• replicate data of the second VM of the second subset of VMs from the source site to the target site based on the synchronous mode of replication in parallel with the migration of the first VM for dynamically adjusting a recovery time objective parameter;
• subsequent to the parallel migrating and replication of at least one VM of the first subset and second subset, determine whether a resource consumption of the virtual computing system is less than or equal to a predetermined threshold;
• based on the resource consumption being less than or equal to the predetermined threshold, modify the first subset and the second subset to move the third VM from the first subset to the second subset and migrate the third VM from the source site to the target site in the virtual computing system based on the synchronous mode of replication.

A method comprising:

• monitoring, by a migration controller, resource consumption of system resources;
• determining, by a migration controller, a first subset of a plurality of virtual machines (VMs) to be replicated based on a synchronous mode of replication and a different second subset of the plurality of VMs to be replicated based on an asynchronous mode of replication, the first and second subsets determined based on a priority order of the plurality of VMs in a recovery plan and the resource consumption of the system resources, wherein the first subset includes a first VM and the second subset includes a second VM and a third VM;
• replicating, by the migration controller, data of the first VM of the first subset of VMs from a source site to a target site based on the synchronous mode of replication in anticipation of a failover event;
• in response to the failover event, migrating the first VM of the first subset of VMs from a source site to a target site in a virtual computing system, wherein migrating the first VM includes powering off the first VM at the source site and powering on the first VM at the target site;
• in response to the failover event, migrating, by the migration controller, the second VM of the second subset of VMs from the source site to the target site in the virtual computing system based on the asynchronous mode of replication, wherein migrating the second VM includes replicating the second VM from the source site to the target site based on the asynchronous mode of replication, powering off the second VM at the source site, and powering on the second VM at the target site;
• subsequent to the migrating and replication of at least one VM of the first subset and second subset, determining whether a resource consumption of the virtual computing system is less than or equal to a predetermined threshold;
• based on the resource consumption being less than or equal to the predetermined threshold, modifying, by the migration controller, the first subset and the second subset prior to the failover event to move the third VM from the second subset to the first subset and migrating, by the migration controller, the third VM from the source site to the target site in the virtual computing system based on the synchronous mode of replication.
