This might help you understand AWS pricing! Check your website's data transfer volume

This is Ohara from the China office

When building a server environment on AWS that will be accessed by an unspecified number of users, such as a corporate website or e-commerce site, AWS charges a pay-as-you-go fee for "data transfer volume."

This means that the more connections to a website, the more data is transferred, and therefore the higher the pay-per-use costs

However, it would be good to know, as a rough guide, how much data is being transferred from the target website. In this article, we will explain how to calculate this data transfer amount

Check the number of requests on your website

launch
" Chrome Developer Tools (Please launch it in Google Incognito mode, as cached data may be reflected.)

Open the site, right-click, and then click "Verify." The following screen will appear on the right, so open "Network" (the yellow part)

When you open "Network", the following screen will appear

If you look at the yellow area, you can see that 579KB of data is used per page.
(The amount of data varies from page to page, so please use the same procedure to check about 10 pages and calculate the average.)

Calculating data transfer volume

Let's check the data transfer volume assuming that the average page data per page is 500KB and the average number of sessions per day is 10,000.
(Use the "netstat" command to check the number of sessions.)

■ Calculation formula:
Average page data 500KB x 10,000 average sessions/day = 5,000,000KB = 4,882MB (byte equivalent)
4,882MB x 1 month (30 days equivalent) = 146,460MB

And so it goes

Simulating data transfer charges on AWS

AWS has a management estimator that allows you to calculate approximate monthly usage fees

Please use this link!
Amazon Web Services Simple Monthly Calculator

The transfer volume I checked earlier was 146GB, so I will enter 146GB of transfer volume to get an estimate

The monthly fee is $18.34 (for the Tokyo region).
If we convert this to 1 dollar = 120 yen,

18.34 USD x 120 yen = 2,200 yen per month

*By the way, there is no data transfer charge for receiving (incoming) data from the Internet to AWS EC2

summary

The data transfer fees are only a guideline, so they may not be exactly the same as the simulation, but they should serve as a guideline for companies considering building and operating on AWS

However, there are other cloud services besides AWS that offer plans with unlimited data transfer

Also, if you're not particular about the cloud, why not consider a managed hosting service?

As an aside, at Beyond, we often have the opportunity to build, operate, and maintain various IaaS services, including AWS, and in doing so we often have the opportunity to speak with representatives from vendors that provide cloud services.It seems that a recent trend is an increase in contracts for traditional managed hosting

If you want to talk to a cloud professional

Since our founding, Beyond has used the technical capabilities we have cultivated as a multi-cloud integrator and managed service provider (MSP) to design, build, and migrate systems using a variety of cloud server platforms, including AWS, GCP, Azure, and Oracle Cloud

We provide a custom-made cloud server environment optimized for our customers based on the specifications and functions of the systems and applications they require, so if you are interested in the cloud, please feel free to contact us
