Capacity Estimation for Content Delivery Network (CDN)

You can estimate the system capacity by analyzing certain data like traffic, number of user coming on site, storage requirements, etc. By analyzing whole data we can further calculate the required storage capacity for whole year. Here is the simplified calculation given:

Traffic is 50,000 vistors per month

Traffic per second = 50000/30*24*60*60
= 0.019

Assumption- 40% of requests served by CDN
20% of static content vs. dynamic conten

TPS – 40+20 =60
Storage required (approx 200kb/file size) = 60*200 = 12000 KB/S = 12 MB/S
Storage required per year = 12*60*60*24*365 = 378TB
