It might be a guide to AWS prices! ? Check the amount of data transferred on a website

This is Ohara from the technical sales department.

When building a server environment on AWS that is accessed by an unspecified number of users, such as a corporate site or an e-commerce site,
AWS charges a pay-as-you-go fee based on the amount of data transferred.
This is because the more connections there are to the website, the more the transfer amount will be, and the higher the pay-as-you-go cost.

However, it is important to have a rough idea of ​​how much data is being transferred to the target website.
This article describes how to calculate the amount of data transferred.

■ Check the number of website requests

First, launch
Chrome Developer Tools (Cache data may be reflected, so please start in Google's incognito mode.)

Open the site, "right-click the mouse" → "Inspect", and the following screen will appear on the right side, so open "Network" (yellow part).

When you open "Network", you will see a screen like the one below.

If you look at the yellow part, you can see that 579KB of data is used per page.
(The amount of data differs for each page, so please check about 10 pages using the same procedure and calculate the average value.)

■ Calculation of data transfer amount

Let's examine the amount of data transferred assuming that the average page data per page is 500KB and the average number of sessions per day is 10,000.
(Check the number of sessions using the "netstat" command)

[Formula]
Average page data 500KB × Average 10,000 sessions/day = 5,000,000KB = 4,882MB (byte equivalent)
4,882MB × 1 month (30 days equivalent) = 146,460MB

And so it becomes.

■ Simulate data transfer charges on AWS

AWS has a management estimation tool that allows you to calculate approximate monthly usage fees.

The transfer amount I checked earlier was 146GB, so I will input the transfer amount of 146GB and estimate it.

The monthly fee is now $18.34. (In the case of Tokyo region.)
Converting this as 1 dollar = 120 yen,

18.34 USD × 120 yen = 2,200 yen per month.

*By the way, there is no data transfer fee when receiving data from the Internet to AWS EC2.

■ Summary

Regarding data transfer charges, this is only a guideline, so it may not necessarily be exactly as simulated, but
I think it will be a good guideline for companies considering building and operating on AWS.
However, there are cloud services other than AWS that offer plans that allow unlimited data transfer.
Also, if you are not particular about the cloud, why not consider managed hosting services?

Digression

At Beyond, we have many opportunities to build and monitor and operate various IaaS such as AWS and IIJGIO, and

among these, we often have the opportunity to talk with representatives of vendors who provide cloud services. The trend seems to be that traditional managed hosting contracts are increasing. Is it a return to basics?
