10. A method of deploying an operating system on a plurality of computing devices, the method comprising:

performing a first portion of an installation process on each of the plurality of computing devices asynchronously across the plurality of computing devices; and

performing a second portion of the installation process on each of the plurality of computing devices concurrently.

11. A method as recited in claim 10, wherein performing the second portion comprises downloading an operating system image to the plurality of computing devices.

12. A method as recited in claim 10, wherein performing the first portion comprises:

downloading a deployment agent loader to obtain, from each of the plurality of computing devices, information describing hardware installed on each of the plurality of computing devices; and

downloading, to each of the plurality of computing devices, a deployment agent, wherein the deployment agent downloaded to a particular computing device is generated based on the received information regarding the particular computing device.

13. A method as recited in claim 10, further comprising adding an indication of the installation process performed on each of the plurality of computing devices to a log.

14. One or more computer readable media having stored thereon a plurality of instructions that, when executed by one or more processors, causes the one or more processors to:

receive, from each of a plurality of computing devices, an indication that the computing device is to have an operating system installed on the computing device;

for each of the plurality of computing devices, identify, in response to receiving the indication, a set of steps to be taken in order to install an operating system on the computing device; and

control installation of the operating systems on the plurality of computing devices asynchronously and in parallel.

15. One or more computer readable media as recited in claim 14, wherein the indication that the computing device is to have an operating system installed is an indication that the computing device has been powered-on.

16. One or more computer readable media as recited in claim 14, wherein one or more of the plurality of computing devices currently has no operating system installed.

17. One or more computer readable media as recited in claim 14, wherein one or more of the plurality of computing devices currently has an operating system installed.

18. One or more computer readable media as recited in claim 14, wherein the installation comprises transferring multiple portions of data to each of the plurality of computing devices, and wherein some of the multiple portions are transferred to the plurality of computing devices in parallel and other of the multiple portions are transferred to the plurality of computing devices asynchronously.

19. One or more computer readable media as recited in claim 18, wherein the portions that are transferred to the plurality of computing devices in parallel are larger than the portions transferred to the plurality of computing devices asynchronously.

20. One or more computer readable media as recited in claim 18, wherein the portions that are transferred to the plurality of computing devices in parallel comprise an image of the operating system being deployed.

21. One or more computer readable media as recited in claim 14, wherein the instructions cause the one or more processors to perform multiple steps of the set of steps asynchronously across the plurality of computing devices, and, after a particular one of the set of steps is completed, to perform one or more of the remaining steps of the set of steps in parallel across the plurality of computing devices.
