Wrong Estimation or formula used

The end result of the detailed calculation is that 15 servers are required.

Then in the next paragraph they basically say this isn’t a great estimate followed by this:

Therefore, we approximate the number of servers by depicting how many clients a server handles on a given day:

That formula gives a result of 62500, but it doesn’t make sense to me for reasons as explained in my original post and it doesn’t agree at all to the detailed calculation (which appears at face value to be a much better one, even though the result feels intuitively too low).

Hi Ritesh.

We are glad you reached out to us. The reasoning behind this formula instead of the first one is pretty simple. We assume that all active users will send one request to the system at once. This allows us to reach a much better estimation of the number of servers we will need to keep the system running at peak loads.

Remember, these are just informed estimations, and our objective is to estimate the resources required to run a system. In reality, these numbers are refined during the later stages of the development of the system.

If you have any other questions, feel free to reach out to us.

Thank you.
