## Abstract

Embodiments described herein are directed to reinitiating an application on a target computing cloud and to evaluating potential target cloud computing systems. In one scenario, a computing system receives an indication that identifies a target cloud for application migration. The target cloud computing system includes a specified set of hardware and/or environment specifications, associated configuration settings and an assigned rating that indicates how well the application will perform on the target cloud computing system. The computing system determines that the application is to be reconfigured for compatibility with the target cloud computing system and reconfigures some or all of the application to comply with the hardware and/or environment specifications and configuration settings of the target cloud computing system. The computing system also identifies and transfers specified portions of the application to the target cloud, and indicates that the application is to be re-instantiated using the transferred application portions.
