The N1 Provisioning Server manages software images and configurations of servers. The N1 Provisioning Server supports creation and management of two categories of images: global images and account images.
Global images consist of the operating system (including patches and service packs), integrated N1 Provisioning Server agents, and certain customizations. Global images may also contain applications. At the very least, the customizations are modifications that make images compatible with an I-Fabric. You also may choose to customize images with account-specific software and data.
Account images are for a particular account and consist of account-specific customizations of global images, blank disks, or application and data images.
