I was quickly hooked to Amazon S3 storage via the free account creation offer on Amazon Cloud's website. AWS offers 5 free gigabytes of cloud storage, which is interesting if, as in my case, you need to host big files permanently, that could hardly be stored via standard wordpress installation. Of course you could increase upload limit but I am afraid this could be security issue.
It turns out that the AMAZON WEB SERVICES is a cluster of different hosted applications, among which S3 is the simplest to use : it is no more than a file storage utility with a web based browser, web access to files, and various protection features.
If you want to host your WORDPRESS Media files on AMAZON S3, you need to install a plugin. I tried the WP READ ONLY plugin that is very easy to configure. All you need is to have configured your S3 account :
- choose a bucket (some kind of folder for amazon S3),
- your amazon credentials : developer key and SECRET KEY
