I'm setting up a Magento site on AWS for the first time and want to use a S3 bucket with Cloudfront CDN.
I want to store the media folder in an s3 bucket so that I can scale out the servers and they will all use the same S3 bucket. And use the CDN to speed up performance.
I've been doing a some research and it all recommends that I use an extension such a this one.
Why would I need to use an extension? I thought I could simply set the Base Media URL to use our bucket URL to my Magento config at System > Configuration > Web
Do you just need to use an extension for the CDN part? i.e. can I use the s3 bucket by simply adding the configuration above?
