I do similar for my personal website on Azure, they have a Wordpress plugin that maps the upload folder to use a blob storage instance. It's a bit dated and doesn't support things like custom domains using https (for the blob.) Something I hope they address (it's 2016 guys.) I don't know if this Amazon solution does the same thing or not. However currently I have to use my Blob's CNAME domain to serve assets over https. I use Cloudflare to manage my certs instead of Cloudfront like they do here. I'm looking for a solution for my agency to put sites onto hosted instances like AWS or Azure, but my hesitance is that they aren't managed solutions and I'm afraid of getting hacked. Does anyone have any insight on how secure these solutions can be? My Azure instance has been running for years without problems, but that's my gamble with my one site and not hundreds of customer sites. I use CloudFlare's page rules to add extra security and caching and have WordFence just in case. I'd love some insight into how I could scale a solution like this to be hundreds of sites on cloud instances while maintaining security. Perhaps they should all be separate? Would my personal solution be good for my company's clients? Managed solutions like WPEngine are just outrageously expensive for some of the sites we have that only get a handful of traffic (Azure offers Wordpress on Azure websites.)
