Another option is a fuse level driver that maps cloud storage to a drive path.

There is a good article here on how to do this using MapServer and S3, this may work for Google as well




You can configure MapServer as a WMS server and add the layers to Open Layers or take the extra step and configure MapCache to generate a tiled output and caching using your WMS as source
