High-availability for power-managed virtual desktop access

A method comprising:

• sending, from a power and capacity management (PCM) service, hypervisor credentials and lists of virtual machines (VMs) to a plurality of high-availability (HA) services running in a plurality of data centers having one or more appliances, VMs and hypervisors configured to power the VMs on and off, wherein the HA service is deployed within a stateless container running on an appliance of the one or more appliances, the appliance being separate from the hypervisor, and wherein the HA service is configured to automatically synchronize with the PCM service at startup;
• receiving, by the PCM service, a health check request from at least one of the HA services to determine if the PCM service is able of selectively power VMs from a list of VMs on and off according to one or more criteria;
• and
• sending, by the PCM service, a response to the at least one of the HA services indicating that the PCM service is unable to selectively power the VMs from the list of VMs on and off according to the one or more criteria, wherein the at least one of the HA services is configured to power on one or more of the VMs from the list of VMs using the hypervisor credentials received from the PCM service.

An apparatus located in a data center having one or more appliances, a plurality of virtual machines (VMs) and a hypervisor configured to power the VMs on and off, the apparatus comprising:

• a processor;
• and
• a non-volatile memory storing computer program code that when executed on the processor causes the processor to execute a process operable to:
• receive credentials for the hypervisor and a list of VMs from a power and capacity management (PCM) service running outside the data center, the PCM service configured to selectively power VMs from the list of VMs on and off according to one or more criteria, wherein the HA service is deployed within a stateless container running on an appliance of the one or more appliances, the appliance being separate from the hypervisor, and wherein the HA service is configured to automatically synchronize with the PCM service at startup;
• send a health check request to determine if the PCM service is able of selectively power the VMs from the list of VMs on and off according to the one or more criteria;
• and
• in response to determining the PCM service is unable to selectively power the VMs from the list of VMs on and off according to the one or more criteria, power on one or more of the VMs from the list of VMs using the hypervisor credentials received from the PCM service.
