Flatcar Container Linux LTS is a Long Term Support edition of Flatcar Container Linux, ideal for production container environments requiring the highest stability and security.
Flatcar Container Linux LTS is a self-updating operating system designed for containers, making it ideal for running Kubernetes and other container platforms. It is suitable for anyone deploying containerized applications, particularly those seeking to do so securely or at scale.
Why users choose Flatcar Container Linux LTS
Security: A minimal distribution with immutable file system meets NIST recommendations for application container security ("Whenever possible, organizations should use these minimalistic OSs to reduce their attack surfaces and mitigate the typical risks [of] general-purpose OSs.")
Auto-updating: With Flatcar's robust auto-update mechanism, it's easy to keep your entire fleet up-to-date with the latest capabilities and security patches, and roll-back in the event of an upgrade issue on a specific instance.
Reduced complexity: As a minimal distribution, Flatcar includes just those components you need to deploy your containers, and nothing more. Also, its immutable file system and auto-update mechanism means it requires minimal operational support.
Long Term support: Flatcar Container Linux LTS is maintained for an extended lifetime of up to 18 months, making it ideal for users valuing stability over new features.

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, so the software itself carries no license charge. You pick from many ARM-based EC2 instance types, each billed per hour. The dimensions map to AWS instance families like a1, t4g, c6g, m6g, r6g, x2gd, g5g, im4gn, and is4gen, plus their size variants from nano through metal. Each family targets a workload profile such as general purpose, compute, memory, storage, or graphics. Larger sizes within a family provide more CPU, memory, or storage. Your cost scales with the instance size and family you run.
Top-of-mind questions for buyers
The software is free, so what does the hourly rate on each instance type cover?
The listing itself carries no software license charge. Each hourly rate reflects the underlying AWS EC2 compute cost for the ARM-based instance you launch. You pay for the running instance, not for the operating system. Your bill scales with the instance family and size you choose.
Am I charged for an instance that is stopped or powered off?
Hourly charges apply only while an instance runs. Fully stopped instances do not accrue compute charges for this listing. You may still owe AWS storage fees for attached volumes on a stopped instance. The metering counts running hours.
What decides how much CPU, memory, or storage I get per instance type?
Each family targets a workload profile. Compute families favor CPU, memory families favor RAM, and storage families add local disk. Within a family, size labels from nano through metal scale the resources up. A larger size gives more CPU, memory, or storage, and costs more per hour.

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.
