3.10 Summary
The first step in working with Ubuntu is to install the operating system. In the case of a cloud-based server, this task is typically performed automatically when an operating system image is selected for the system based on a range of options offered by the cloud service provider. Installation on your own hardware or in a virtual machine, however, involves downloading the installation media in the form of an ISO image, writing that image to suitable storage such as a DVD or USB drive and booting from it. Once installation is complete, it is important to install any operating system updates that may have been released since the original installation image was created.
