Anyone know something like these but that supports GPU? I'm struggling a bit to figure out the best way to host a demo that involves a deep learning component. Usage is expected to be bursty so I don't want to constantly have to rent an unknown number of instances just because I don't know when people will use it. Seems like a good use case for "serverless" but those (Lambda, etc) don't seem to support GPU either. Maybe I need some DL-specific backend service instead of going for a regular web host?
