In certain embodiments, a computer-implemented method includes accessing, using one or more processing units, application parameters associated with an application. The application parameters define constraints for hosting the application using one or more of a plurality of provisioned computing environments available over a computer network from multiple computing resources vendors. Each vendor is associated with a corresponding vendor-specific provisioned computing environment that includes computing resources available to be provisioned for use by a multiple entities distinct from the vendors. The method includes accessing, using the one or more processing units, vendor-specific data for the vendor-specific provisioned computing environments. The method includes determining, using the one or more processing units, from among the vendor-specific provisioned computing environments and based on the application parameters and the vendor-specific data for the provisioned computing environments, a first vendor-specific provisioned computing environment for hosting the application.
