An interim Ubuntu Linux release optimized for AWS. This production-quality version lets you try the latest open source software before the next LTS, with 9 months of support.
Ubuntu is the world's most popular Linux for cloud environments and is suitable for small to large-scale Linux operations. Ubuntu Server for AWS is designed by Canonical (the publishers of Ubuntu) and optimized for AWS. For more information, visit https://ubuntu.com/aws.
Interim releases, issued every 6 months, introduce new features from Canonical and upstream open source projects. They serve as a proving ground for early adopters, testers, and users who need the latest runtimes, kernels, and libraries before the next LTS.
Ubuntu is free and will always be, with the option to access additional security, management tools and technical support when you need it through additional commercial offerings from Canonical.
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
Non-stop security: 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
For professional environments or applications where additional security and compliance would be beneficial, or where you might want to continue using the environment beyond, Canonical recommends an Ubuntu pro subscription (learn more at https://ubuntu.com/aws/pro).

You run Minimal Ubuntu 25.10 with no software license fee. The operating system itself is free, so your cost comes only from the AWS EC2 instance you choose to run it on. Pricing is billed per hour and scales with the instance type you select. Each dimension maps to a specific EC2 instance, spanning general purpose, compute, memory, storage, and accelerated computing families in sizes from small to bare metal. Larger instances carry more compute, memory, or specialized hardware, so their hourly rate rises accordingly. You pick the instance that fits your workload and scale.
Top-of-mind questions for buyers
What do I get for each hourly instance dimension listed?
Each dimension maps to one specific AWS EC2 instance type, such as a general purpose, compute, memory, storage, or accelerated computing machine. The size, from small shared to bare metal, sets the CPU, memory, and specialized hardware you receive. The operating system carries no software fee.
Am I charged when my instance is stopped or powered off?
The operating system carries no software license fee, so no software charge applies at any time. Your hourly cost comes from the running AWS EC2 instance. Stopped or powered-off instances do not accrue instance-hour charges, though AWS storage fees for attached volumes may still apply.
Does my hourly rate change if I switch to a larger instance?
Yes. Each instance type has its own hourly rate. Larger instances carry more compute, memory, or specialized hardware, so their hourly rate is higher. Switching instance types changes your rate to match the new selection. You pick the instance that fits each workload.
