Five Things To Know About Bottlerocket, AWS’ New Container-Optimized Linux

Joseph Tsidulko

AWS introduced Bottlerocket to power containerized workloads running on its own managed container services, and everywhere else.

Native AWS Integrations

“Integration into AWS services is what makes this unique and probably why someone would want this verses a CoreOS or an Alpine,” Ulander told CRN.

Bottlerocket was built to power EKS and ECS. But it doesn’t have to—users of those two AWS-native managed container services will still have a choice of operating systems.

Ulander expects some customers will want to continue to use other Linux versions, like CentOS.

But he encourages the majority of AWS customers now running Amazon Linux with those managed container services to migrate to Bottlerocket.

“Who doesn’t want better security, better speed and a lower price,” Ulander said.

The more AWS can lighten the resource load, the better those distributed applications will perform, he said.

“At the end of the day, it’s a container host, it’s not running your apps,” Ulander told CRN. “It’s not going to make or break your apps as a developer, but it will make or break your experience.”

At the same time, while Bottlerocket is an effort led by AWS and integrated with Amazon’s cloud, it can be deployed in most computing environments.

“It’s a Linux distribution. In a different cloud, you still need to select what your container host OS should be,” Ulander said.
