Ubuntu shops that use cloud services to test server applications can now use an Ubuntu ARM server AMI with Amazon EC2.
The new Ubuntu ARM-based Amazon machine image (AMI) for Ubuntu 12.04 LTS
Recently, Dell released an ARM server but these types of servers aren’t common yet.
Canonical is "staking out this ground, getting it running early, solving the problems they find, so when the hardware is available their OS is ready to go," said John Locke, manager at Freelock Computing, an open-source web development company based in Seattle.
Ubuntu Server 11.10 was the first version to fully support ARM servers which offer several advantages for data centers. Customers can increase server densities, reduce energy, cooling, and space requirements, according to an Ubuntu FAQ .
Though ARM processors offer advantages, they are not general purpose CPUs. For computationally intensive applications, x86 might be a better fit, according to Canonical.
The Ubuntu team originally developed the ARM server AMI internally to test the 12.04 release, said Canonical's commercial engineering director Victor Palau on a blog post.
Now that the image available to the public, Amazon EC2 customers can see how their applications run on Ubuntu for ARM servers, Palau said.
