One of the objectives of PDF is to provide interoperability between various Cloud-infrastructure and Vendors. My work at this internship aims to develop this PDF file further, add more details and develop some toolings around PDF to make it easier to consume by the end-user. The final process will involve validating PDF against installer manifests.
