I have a calculation which runs out of memory on my machine (Windows, 8 GB). I have already spent enough time on optimizing my code, now it's time to get some more power. I have read a lot of specific questions and resources, some fairly out of date, about the details of setting up Mathematica on cloud instances etc. Unfortunately none of those was complete or seemed simple enough for me to do in a short amount of time. On the contrary, I am under the impression that it is something which requires a lot of work and troubleshooting and that just isn't possible for me to do at the moment. On top of that, I know that I will not need it repeatedly in future, it is part of a one-time research and will require few hours in total.
The most interesting offer I found was this: https://www.nimbisservices.com/shop/product/mathematica-on-amazon-cloud-licensing-service/. I had some questions to the offer which I have asked and might post it here afterwards for the record. Other idea was to just get an improvement on my own hardware or link together several smaller machines myself.
What is the easiest way to get more computing power for a one-time computation?
