Your experience with cloud platforms?

I am interested in using some sort of a cloud platform that offers GPU (>=12 GB) and supports Pytorch. It appears like there are a lot of cloud platforms available, and was wondering if someone has any experience with one of them and would like to share.

I will be glad to find a platform that (in addition to “not being the most expensive”) has an available support staff, and allows an easy, and quick start (i.e. a platform that does not require a few hours before the first “run”).

Hope someone will be able to help

Thanks in advance!
