I am currently working on different aspect Google App Engine and still in study phase and build some small apps and deployed it on cloud. Recently when i was installing a command line to for cloud storage(i.e. gsUtil) I encountered versioning support on cloud storage and was able to retrieve old objects or deleted objects through gsUtil . So building a document management system on GAE is good idea with Google cloud storage or I should be using Google drive SDK ?
Please guide me on this problem .
Thanks in advance
