Migrating workloads in multicloud computing environments

A method comprising:

• communicating, by processing circuitry, with a first virtual computing environment (VCE) and a second VCE, wherein a plurality of VCEs include the first VCE and the second VCE, wherein the first VCE represents at least a portion of a public cloud operated by a first public cloud provider, and wherein the second VCE represents at least a portion of a public cloud operated by a second public cloud provider;
• configuring, by the processing circuitry, a disaster recovery controller;
• executing, by the processing circuitry, the disaster recovery controller;
• and
• configuring a plurality of heartbeat agents in the plurality of VCEs, wherein the processing circuitry configures a heartbeat agent of the plurality of heartbeat agents in each respective VCE of the plurality of VCEs, and wherein the method further comprises:
• receiving, by the disaster recovery controller a sequence of heartbeat signals from a heartbeat agent of the first VCE at a rate;
• based on the sequence of heartbeat signals, determining, by the disaster recovery controller, one or more omissions corresponding to the heartbeat agent of the first VCE;
• detecting, by the disaster recovery controller, a failure of at least a portion of the first VCE based on determining that a number of the one or more omissions of heartbeat signals corresponding to the heartbeat agent of the first VCE exceeds a threshold number of omissions;
• and
• outputting, by the disaster recovery controller to the first VCE and responsive to detecting the failure, an instruction to transfer a workload from the first VCE to a second VCE, thereby causing a migration of the workload to the second VCE.

A non-transitory computer medium comprising instructions for causing one or more processors to:

• communicate with a first virtual computing environment (VCE) and a second VCE, wherein a plurality of VCEs include the first VCE and the second VCE, wherein the first VCE represents at least a portion of a public cloud operated by a first public cloud provider, and wherein the second VCE represents at least a portion of a public cloud operated by a second public cloud provider;
• configure a disaster recovery controller;
• execute the disaster recovery controller;
• and
• configure a plurality of heartbeat agents in the plurality of VCEs, wherein the processing circuitry configures a heartbeat agent of the plurality of heartbeat agents in each respective VCE of the plurality of VCEs, wherein the one or more processors cause the disaster recovery controller to:
• receive a sequence of heartbeat signals from a heartbeat agent of the first VCE at a rate;
• based on the sequence of heartbeat signals, determine one or more omissions corresponding to the heartbeat agent of the first VCE;
• detect a failure of at least a portion of the first VCE based on determining that a number of the one or more omissions of heartbeat signals corresponding to the heartbeat agent of the first VCE exceeds a threshold number of omissions;
• and output, to the first VCE and responsive to detecting the failure, an instruction to transfer a workload from the first VCE to a second VCE, thereby causing a migration of the workload to the second VCE.
