I don't think most people really grasp the meaning of Amazon's EC2 service.
Basically Amazon is now the cheapest high-quality dedicated hosting provider in the world. And they offer provisioning functionality no one else can match.
Amazon EC2 - "Elastic Cloud" allows you to run as many Linux boxes as you like. They charge you $0.10 per CPU hour. It gives new meaning to the expression: It's your dime
This equates to $72/month for a server. In comparison, up til now, I've considered $99/month a pretty good deal for a dedicated server.
I'm using the EC2 beta, and created my first machine. I notice using dmesg on my instance that Amazon is running EC2 on top of Xen virtualization:
BIOS-provided physical RAM map: Xen: 0000000000000000 - 000000006a400000 (usable) 980MB HIGHMEM available. 727MB LOWMEM available.
What makes this unique:
Who suffers the most from this little revolution? I think it could be VCs. Software and services entrepreneurs simply won't need as much money to create the next Digg, Flickr, or even Google.
