Thanks Larry, When I mean that I have 62000 users I mean the total users but the real users who they are using the system everyday it is about 15000 unique user and the total is about 18000 user per day. Most of them they are using blackboard (LMS) and other systems like (Drupal, Gmail emails and apps, Kayako, Phpscheduleit system) I will do your suggestion to monitor the memory on my server.

Hi Amjad, My understanding is that the amount of memory it requires depends on the kind of applications being used. But we could definitely make an estimation. One thing I have in mind is to use system monitoring tool to capture the memory usage for current online users and then predicate the maximum memory needed when all possible users are online (in your case 62000) by calculating the average amount of memory individual session requires. There may be a better way to do this, please advise if anyone has more experience of this matter.

We are still in testing environment and we will go live using CAS by 15/01/2013, we have a single VM with 8 GB of memory, 4 core CPU and 100 GB HD. Also we a second VM holding the MYSQL database for CAS management service. is this enough to hold the above number of users.

The short version is that any halfway-decent recent server you've got is fine. Really. CAS runs on commodity server hardware, no worries. I like isolating CAS from other applications on principle, but if you wanted it would almost certainly run fine alongside anything else you've got on any server you're already running. CAS doesn't do much. Needs some RAM to store the ticker registry. Needs some disk to write log files. You're probably offloading SSL to something in front of it so it doesn't even have much CPU load.
