For those of you who are using or plan to use the Microsoft Advanced threat Analytics, are you using the sizing chart located at to size your systems? While it does state that you can install this on a VM, I find it unlikely to be able to obtain a VM from our Virtual Infrastructure team with 48 GB of memory for the ATA Center and Multiple ATA GW’s with 12 GB of memory. Is there anyone finding that these requirements are overkill or does it really require this much memory?   Brian Britt
