+Magento file (cloud) storage systems integration for media files
+=================================================================
+
+Storing media files involve some work when you decide to scale horizontally.
+Also having to care about disk space and disk mounting may be useless when you are already have a easy to use object storage service.
+
+There are plenty of cloud static files storage services offered with various feature but most of them have same basic ideas:
+
+* allow secure upload remotely of files
+* deliver static file public or privately
+* built in Content delivery network (CDN)
+
+With this idea in mind you can identify a use-case for e-commerce website for storing images and video for products, categories or CMS pages and deliver them using a CDN. Or even storing private content like downloadable products.
+
+Using cloud storage should be easy to configure and use, ans should not add additional complexity to the system but on contrary.
+
+Reed the documentation https://magento-filesystem-extension-docs.readthedocs.io to see some of the key advantages of using this Magento 2 extension to integrate with various cloud file storage systems in a platform agnostic manner.
