I know Amazon's EC2 does NOT allow true static IP allocation to the virtual machine instances, but i'm wondering if any of the other cloud hosting providers do? I'm trying to find out if Rackspace does, but havent been able to find anything concrete.

Any inputs on who does or doesn't for sure?

What do you mean by "true static IP allocation"? Amazon provide static IPs via their elastic IP feature, so it would be helpful for you to define what isn't "true" about this to answer your question. – m0dlx Jul 27 '10 at 8:21

Amazon allows for static IP's to allocated to its EC2 instances.

It is actually a pretty interesting concept that allows you to get a static IP address assigned to your account which you can then point to any particular EC2 instance you have running. So if you take a server down, you point the Elastic IP to a new instance and the outside world still uses the same IP.

Here's Amazon's description:

Elastic IP addresses are static IP addresses designed for dynamic cloud computing. An Elastic IP address is associated with your account not a particular instance, and you control that address until you choose to explicitly release it. Unlike traditional static IP addresses, however, Elastic IP addresses allow you to mask instance or Availability Zone failures by programmatically remapping your public IP addresses to any instance in your account. Rather than waiting on a data technician to reconfigure or replace your host, or waiting for DNS to propagate to all of your customers, Amazon EC2 enables you to engineer around problems with your instance or software by quickly remapping your Elastic IP address to a replacement instance.


No cost for Elastic IP addresses while in use. $0.01 per hour when not mapped to a running instance. 100 free Elastic IP remaps per month per account and $0.10 per remap thereafter

Hope that helps.

I think I found the answer for Rackspace

Additional IPs

Additional public IP addresses can be purchased for $2 / month.
