> Amazon updates their severs on your behalf.

No, they don't, unless I am very misinformed about how Amazon VM images work. If I fire up a Debian AMI, it'll update itself, or not. (How would Amazon 'update it on my behalf'? What if it needs a reboot?)

The original article is taking about using Amazon CDN not a VM. When you use this hosting type style you are paying someone else to manage the underlying servers. Same with the people who use S3 or Wordpress or whatever namecheap/godaddy provides for static sites. That’s one of the reasons a VM can be $5 vs a CDN at $50 a month.
