Ubuntu Server delivers services reliably, predictably, and economically. Ubuntu is the world's most popular Linux distribution for cloud environments and is suitable for small to large-scale Linux operations, making it a well-tested base on which to build your instances. Ubuntu Server for AWS runs on an AWS-optimized kernel, which includes optimized, Canonical-maintained device drivers, like ENA, and out-of-the-box support for accelerators like GPUs. This means faster instance starts and better runtime performance for your workloads. For more information, visit https://ubuntu.com/aws.
Ubuntu 26.04 LTS images for EKS are based on the official Minimal Ubuntu images published by Canonical, and include everything you need to attach instances to your EKS nodes. They have been built specifically for the EKS service, therefore are not intended as general OS images.
Ubuntu is free and will always be, with the option to access additional security features, management tools and technical support when you need it through additional commercial offerings from Canonical.
You can upgrade to Ubuntu Pro to get enhanced security features, compliance and uptime and grant your cluster the capability to run an unlimited number of Ubuntu Pro containers.
Why developers and devops choose Ubuntu Server for AWS
Production-ready: Ubuntu is the leading Linux in the public cloud with > 50% of Linux workloads
Developer friendly: Ubuntu is the #1 Linux for developers offering the latest library and tools to innovate with the latest technologies
No mandatory licenses: Ubuntu Server is freely available, with no mandatory licenses and unlimited VMs
Continuous security updates: Canonical publishes images on a daily basis, ensuring security is built-in from the moment an instance launches
Optimized performance: optimized kernel, with improved boot speed, outstanding runtime performance and advanced device support
Portability: Ubuntu is available in all regions with content mirrors to avoid the need to go across regions or out to the Internet for updates
5 years of patching and maintenance: Ubuntu 26.04 LTS for EKS offers 5 years of standard security maintenance from its release date. This can be extended to a total of 10 years with an Ubuntu Pro subscription. Furthermore, the maintenance can be extended for an additional 5 years using the Legacy add-on.

AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
This listing is free to use, so the software itself carries no charge. You pay only for the underlying AWS compute you select. Each dimension maps to one Arm-based EC2 instance type, billed per hour. Options span general-purpose, compute-optimized, memory-optimized, storage-optimized, and GPU-accelerated families, in sizes from nano and medium up to bare-metal configurations. Your hourly cost scales with the size and family you choose; larger instances cost more per hour. You run this Ubuntu image on EKS worker nodes and pick the instance type that fits your workload.
Top-of-mind questions for buyers
What does one hourly unit cover — the software, the EC2 instance, or both?
Each hourly unit maps to one running Arm-based EC2 instance type you select. This listing's Ubuntu image is free, so the software adds no charge. You pay the standard AWS hourly rate for the chosen instance while it runs. Each instance you launch is metered separately.
Am I charged when an instance is stopped or when worker nodes scale down?
Hourly charges apply only while an instance runs. Stopped instances stop accruing hourly charges, though attached storage may still incur AWS fees. When your EKS worker pools scale down, the removed nodes no longer bill by the hour. Scaling back up resumes hourly charges on active nodes.
Does moving to a larger instance type change how I am billed?
Billing stays per hour regardless of instance type. Moving to a larger size within the same family, or to a different family, changes the hourly rate you pay. Larger instances cost more per hour. The Ubuntu software remains free across every instance type, so only the AWS compute rate shifts.

An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
