A policy engine is situated within the communications path of a cloud computing environment and a user of the cloud computing environment to comply with an organization's policies for deploying web applications in the cloud computing environment. The policy engine intercepts communications packets to the cloud computing environment from a user, such as a web application developer, for example, in preparation for deploying a web application in the cloud computing environment. The policy engine identifies commands corresponding to the communications packets and directs the communications packets to appropriate rules engines corresponding to such commands in order to execute rules to comply with an organization's policies. Upon completion of execution of the rules, the communications packets are forwarded to the cloud computing environment if they comply with the policies.
