Use Amazon S3 as the file storage backend for your store.
Thai's S3 extension for Magento 2 allows retailers to upload their catalogue and WYSIWYG images straight to Amazon S3.
This extension is easy to use with little configuration! You only need to follow a few simple steps (and one of them is simply to create a copy of your images as a precaution) to get up and running!

Complex file syncing between multiple servers is now a thing of the past with this extension. All your servers will be able to share the one S3 bucket as the single source of media.
CloudFront CDN supports using S3 as an origin server so you can significantly reduce load on your servers.
See the Installation page on the wiki.
There's a Troubleshooting page on the wiki that I'll try and keep up to date with any issues that the community might have with the extension.
No, the S3 extension only syncs across the media folder. You will need to find an alternative solution to store your log files.
I recommend taking a backup of your media files when switching file storage systems. Unfortunately, there's nothing I can do if you somehow accidentally delete them.
