In many cases, there are people who don't do their homework and set up regular, VPS-like web servers on EC2. What happens then, is that they have a real, established website that, weeks, months or years down the road, eventually gets rebooted, and disappears.

The EC2 instances boot to 'boot images', basically. Most of the images are like CDs, and contain just enough to get you ready to install your webserver, database, yadda yadda.

You can configure your image how you like, and then create a new 'image', which will be what your machine looks like after a reboot, but unless you use a persistent data store or external storage of some sort, you can't add new blog posts and expect them to be there after a reboot.

There are easy ways around it, and in fact, are best practices for application design, but compared to the normal shared hosting or VPS configurations that most people know, it is completely different.

Oh hah, I wasn't even thinking like that.

Yep, it's a good idea to save your work.
