A cross-platform deployment computing system receives an application to be deployed to a cloud. The application is parsed to identify assignment criteria and is assigned to an application availability group the defines security that defines a topology in which the application will be deployed. The application is then provided to a control plane for deployment at a target remote server architecture. In order to deploy the application to a different remote server architecture, the control plane for the different remote server architecture accesses the deployment definitions in the AAG and deploys the application to the different remote server architecture using the deployment definitions in the AAG to which the application is assigned.
