1. A method comprising:
- provisioning, by one or more computer processors, an instance, wherein the instance includes one or more local disks, and wherein the instance resides in a secured environment;
shutting down, by the one or more computer processors, the instance;
attaching, by the one or more computer processors, an in memory boot image to the instance, wherein the in memory boot image includes an operating system;
changing, by the one or more computer processors, a boot sequence such that subsequent booting of the instance utilizes the attached in memory boot image;
booting, by the one or more computer processors, the instance with the in memory boot image such that the operating system exists in a main memory of the instance;
copying, by the one or more computer processors, an image file to the one or more local disks of the instance, wherein copying the image file overwrites the one or more local disks; and
rebooting, by the one or more computer processors, the instance.

Abstract
In one approach, one or more computer processors provision an instance in a cloud computing environment, wherein the instance includes one or more local disks. The one or more computer processors boot the instance from a boot image such that an operating system exists in a main memory of the instance. The one or more computer processors copy an image file to the one or more local disks of the instance, where copying the image file overwrites the one or more local disks. The one or more computer processors reboot the instance.
