Ubuntu Boosts Linux Performance on AWS Cloud


Running Ubuntu Linux on the Amazon Web Services (AWS) cloud is a fairly common practice. Though Ubuntu has been available in the AWS marketplace for years, until recently there wasn’t a version of Ubuntu with a Linux kernel that was specifically tuned for the AWS environment.
Udi Nachmany, head of public cloud at Ubuntu/Canonical, announced in an April 5 blog post that as of March 29, there were Ubuntu cloud images for Amazon that included an AWS-tuned kernel.
The specific kernel at this point is the Linux 4.4.0-1013.22 kernel that is aligned with the Ubuntu 16.04 release.
According to Canonical, the AWS-tuned kernel offers up to 30 percent faster kernel boot speed over a stock Ubuntu Linux kernel running in AWS.
The tuned kernel also takes direct advantage of AWS’s Elastics Network Adapter (ENA). The ENA technology first became available on AWS in June 2016, providing high throughput of up to 20G bps for virtual instances.
When ENA debuted it was supported inside of the Amazon Linux AMI by default. The Amazon Linux AMI is loosely based on Red Hat’s Fedora community Linux project. Now Ubuntu users will be able to easily and directly benefit from ENA as well.
