I have a requirement to assist an NGO to set up a VC solution to train kids in school. I have some credits in my AWS and want to utilize it. However, to estimate the instance requirements, I need some help as I do not have an idea on how to estimate the users/call to the instance count required to scale the load to 20K users.
The scenario is as follows:
Total call duration/day - 8 Hours
Total users/call - 35-40 Users
Total users of the application - 20,000 students
Approximate calls/day - 400-500 calls
I need to know the instance type and instance count that I got to have in place in my account to cater to the above needs.
