I don't really understand the advantage. Getting a small vps with nginx is fast to set up, needs very little maintenance and can handle a large amount of traffic (requesting static pages). Can't really see how S3 can be cheaper or easier. Yes it gives some scalability, but so do many cloud providers. Digitalocean and Vultr both have SSD storage that you can attach to VMs. The speed I've seen is fast enough to easily saturate the bandwidth. Of course you'd need to scale up when you need bandwidth of more than 100mbit, but this is still cheaper than paying for AWS bandwidth and servers.
