Ubuntu 11.04 (Natty Narwhal) 
The Ubuntu Cloud image can be run on your personal Ubuntu Cloud, or modified, rebundled and uploaded to Amazon EC2. For further instruction on setting up a personal Ubuntu Cloud, see Getting Started with Ubuntu Cloud
There are two images available, each for a different type of computer:
- 32-bit Cloud image
- For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors. Choose this if you are at all unsure.
- 64-bit Cloud image
- Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead.
