1. A non-transitory machine readable storage medium comprising instructions embodied thereon, the instructions upon execution by a processor cause a system to: receive a request to launch a computing instance in a computing service environment; provide instance features associated with the computing instance and physical host features associated with a group of physical hosts in the computing service environment to a machine learning model; determine estimated launch times for launching the computing instance on individual physical hosts in the computing service environment using the machine learning model; and select a physical host from the group of physical hosts to provide placement of the computing instance according to a lower estimated launch time as compared to other physical hosts in the group of physical hosts.
