Hello back, about AWS, I think I have seen somewhere that it can be done via FTP, you're 100% right, I knew that I just don't remember because I used it occasionally, the thing is that SAS onDemand support so much more "SAS modules (like SAS OR)" that SAS UE does not, not even in AWS. On the other hand, If you have tried proc like IML in SAS OnDemand, you will notice an extreme fastness with regard to calculation speeds, I'm not convinced of the SAS OnDemand host properties, but I'm pretty sure it is about a Intel Xeon with high power memory resources, which compared to my Intel i7 and limited memory is way faster for numerical calculations and related topics, thereby even if I get it installed in my local machine still will be pretty slow, I encourage you to find the inverse of a 1000x1000 matrix using IML in SAS OnDemand, to make the story short the answer is 1-3 seconds, if I try so in my laptop I could get some sleep and by the time I be back am sure it still won't make, so SAS OnDemand is really fast (also importing large files). Thanks
