Cloud remote wakeup

A technique for leveraging cloud resources includes maintaining a resource index for a user for resources that are available from a connected standby device. The resource index can store an identification of resources for an entity (e.g., a user or enterprise) that is stored on a connected standby device. The resource index can include resources of other devices, as well. A connected standby device will generally have at least three power states, online, offline, and connected standby. When a device is online, a processor of the device is powered up and capable of handling, e.g., remote requests for resources. When a device is offline, the device may or may not be off, but is in any case not responsive to remote access. When a device is on connected standby, a processor of the device is powered down, but the device is responsive to a wakeup packet, enabling the device to respond to a resource request, typically after a short delay while the processor powers up.
