Overview
I had the opportunity to use mdx’s object storage, so this is a memo.
Pricing
The pricing for fiscal year 2024 is as follows.
It costs 0.01 points (yen) per GB per day, which is approximately 0.3 yen per GB per month.
Application Method & Usage with s3cmd
The following official tutorial video was helpful.

Using Cyberduck
The video above introduces file operations using command-line tools.
Here, we will use Cyberduck to perform file operations through a GUI.
The following article introduces how to use Cyberduck with AWS S3. We will reference this method to connect to mdx’s object storage.
Connection Settings
Configure the connection from “New Connection.”

Select “Amazon S3” and enter “s3ds.mdx.jp” as the server.
Then, enter the issued “Access Key ID” and “Secret Access Key.”
Creating a Bucket
You can create a bucket by right-clicking > “New Folder.”


Uploading Files
We will use the following image from Irasutoya.
You can upload by dragging and dropping into the “satoru196” folder.

As also mentioned in the official tutorial above, you cannot view the file by accessing the following URL as-is.

An error code like the following will be displayed.
Changing the ACL
Right-click the file and click “Info.”
Select “Everyone” as follows,

and grant READ permission.

As a result, you can view the image from the following URL.

Summary
There are various uses for mdx’s object storage, but for example, it seems possible to publish media inexpensively. In particular, it could become a powerful infrastructure as a source for publishing media in digital archives.
I hope this is helpful when using mdx’s S3-compatible object storage.
