Abstract: Information Technology (IT) system configuration is managed using a set of defined flows with atomic execution properties. The instructions to execute a change to one or more infrastructure elements (a “forward transaction”) are maintained with instructions and/or information needed to execute a corresponding “reverse” transaction that is responsible for returning the element(s) to a pre-transaction action state in the event of a configuration failure or other request originating at a high level flow.

Abstract: A method includes transmitting a list of virtual machine templates from a cloud management system for display to a user, the list indicating for each virtual machine template a particular region from among plural cloud regions defined as a source region in which the virtual machine template is located. A copy request is received at the cloud management system, indicating one of the virtual machine templates to copy from its associated source region to a selected destination region. The copy request is transmitted to a first cloud control server in the selected source region. The selected template is read from a block storage device in the source region and transmitted to a second cloud control server in the destination region. At the second cloud control server the transmitted template is stored to a destination virtual machine template at a block storage device in the destination region.
