Btw: I shared this quite a while ago, but Oracle is still offering "free forever" VMs. You get 100 GB total disk space, one CPU per VM, 1 GB memory per VM and 10 TB outbound traffic per month and up to 2 VMs. 

While they are indeed slow, it's still a viable solution if you want to host "just" a small website or some data.

Or you could join a collaborative cluster with it.

The cool thing is that they are available in some regions where you might usually don't have many nodes. I've chosen Mumbai, India :)
