There is a link on this forum with NP 17.1 installation guide. Could not find the same one for recently released 17.2 version (I need to do a fresh install). It's not available on the download site either.
I am planning to use AWS r3.4xlarge system for these installations (128 GB RAM, 16 CPUs) and this system should not have significant users' traffic during loading and reports generation tasks execution.
Thank you for thinking about improving this combination in the future..
