This listing is free software, so you pay no license fee for the operating system itself. Pricing is organized by AWS EC2 instance type, billed per hour. Each dimension maps to a specific instance size and family, from small general-purpose machines to large memory-optimized, compute-optimized, and accelerated GPU instances. Your hourly cost scales with the instance you select: larger or more specialized instances carry higher rates. Because the software carries no charge, the hourly amounts shown reflect the underlying compute capacity you run, not a fee for the operating system.
Top-of-mind questions for buyers
What does one hourly unit cover, and what is not included in the software charge?
Each dimension maps to one AWS EC2 instance of that type, billed per running hour. The operating system carries no license fee, so the hourly amount reflects the underlying compute you run. Separate AWS charges for storage, data transfer, and other services still apply.
Am I charged for instances that are stopped or powered off?
The software itself is free, so the operating system adds no license fee whether an instance runs or sits idle. Hourly charges track the compute capacity of running instances. Stopped instances stop accruing compute-hour costs, though AWS storage fees for attached volumes may continue.
Do I need a paid subscription to receive security updates on this image?
This listing is free and includes five years of maintenance and security updates under the LTS release. Longer coverage, kernel patching without reboot, and compliance hardening tools come through a separate paid subscription attached on top of the image, not through this listing.

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.

Usage instructions
For Ubuntu Cloud Guest it is suggested to manually configure your Security Group/Firewall settings. The 1-Click Security Group opens only port 22 so that you can access your instance via ssh using login 'ubuntu'. If you chose the 1-Click Security Group, you may change it later to enable applications using the AWS Console or API.

To connect to instance, your SSH client must support newer standards.

Review from a verified AWS customer
Those who are unaware of the following change may find that they cannot connect to this type of instance with SSH. (It loses a star because this requirement was not apparent and required no little effort to uncover.)
With the 22.04 Jammy Jellyfish release, an older, vulnerable standard for SSH communication has been deprecated. That is an improvement in security, but it has consequences that can mysteriously cause grief to those who are not forewarned.
PuTTY 0.74 or earlier won't connect via SSH. (Upgrade to PuTTY 0.76 or later.) The current latest WinSCP (5.19.6) or earlier also will not connect via SSH, but version 5.20 (currently in beta) will.
