Antenna Simulation using a cloud based computer!?

I have been considering options for dealing with the need for large amounts of RAM to model larger antenna problems (with HFSS in particular).

I found one thread here ( https://www.edaboard.com/thread123465.html ) with a single post and a similar question. It was posted several years ago but did not seem to spark interest.

Has anyone tried this approach? (And, how did it work?)
