Microsoft announced to support Cray Supercomputers on Azure last month https://azure.microsoft.com/en-us/blog/cray-supercomputers-a... I don't know if you can use them today though.

I may buy an hour service and see whether or not an easy window appears to me.

But it seems hard because there is lost of training videos in the site :(

I see hours of videos titled Intro to HPC.

It should not be that much hard.
