Amazon Machine Image (AMI) contents for an AWS Cloud9 EC2 Development Environment

Use the following information to get details about Amazon Machine Images (AMIs) that AWS Cloud9 uses for an EC2 environment.

Important

If your environment's Amazon EC2 instance is based on an Amazon Linux 2 AMI or an Amazon Linux AMI template, security updates are installed on the instance immediately after it's launched. And security patches are then automatically applied to the instance every hour. These updates are applied by a background process and don't affect your use of the instance.

For an Ubuntu EC2 environment, security updates are also installed on the instance immediately after it's launched. Then the unattended-upgrades package automatically installs available updates daily.

Amazon Linux 2/Amazon Linux

Important

We recommend that you choose the Amazon Linux 2 option when creating an Amazon EC2 environment using the console. As well as providing a secure, stable, and high-performance runtime environment, Amazon Linux 2 AMI includes long-term support through 2023.

The standard support for the previous version of Amazon Linux AMI was discontinued on December 31,2020. Now this previous version only receives maintenance support. For more information, see the Amazon Linux 2 page.

Unless otherwise specified, references to Amazon Linux in this topic refer to both Amazon Linux and Amazon Linux 2 instances.

cat /etc/system-release
