Question

Computer networks

Good afternoon friends! How to calculate the required Internet speed for 30 servers? For example, is 100 Mb/s enough to start with? And gradually increase the speed ....
They plan to create a project, the entire load will be on the website, with an increase in site traffic.
Plus, please tell me, for the future, with, say, about 50 million people attendance, what speed should the provider provide for the necessary needs?

Answer 1

Banal:
look at how much your site pages weigh.
Recalculate how many pages you can physically transfer per second on this channel (don't confuse only that weight is usually measured in bytes, and throughput is in bits).
Compare with how much your backend can chew.

Answer 2

Of course, you can’t just count it on the forehead, since there is no correlation between the number of servers and the bandwidth of the Internet channel - you can send or receive 100 megabits with one server, or you can not use ten megabits even with ten.
What kind of traffic will be? How many clients, hits? How many sessions at the same time?

Answer 3

Social network, for starters, during the year we plan to visit 25 thousand people, at the same time 10 thousand. Within 5 years, bring attendance to 100-200 million people, the session is about 8-10 million.

Answer 4

You can not count how the band will end, just increase it.
