This disclosure relates generally to computer resource management over multiple cloud platforms, and more particularly to a system and method for provisioning of application environment and deployment of application across hybrid cloud platform. In one embodiment, a method is provided for provisioning an application environment across a hybrid cloud platform. The method comprises generating a platform independent provisioning template based on at least one of a resource specification and a configuration data. The platform independent provisioning template is compatible with multiple cloud platforms. The method further comprises generating a plurality of target platform artifacts compatible with a corresponding plurality of target cloud platforms based on at least one of the resource specification and the configuration data, associating the plurality of target platform artifacts with the platform independent provisioning template, and provisioning the application environment across the hybrid cloud platform by executing the platform independent provisioning template on each of the plurality of target cloud platforms.
