There are three major differences in Amazon Linux 2 from its predecessors:
## What is Amazon Linux 2023?

1. it is available as a VM image for on-premises development and testing
2. it includes systemd service and systems manager as opposed to System V init system and also includes new version of compiler and build tools
3. it gives you the ability to install additional software packages through Extras mechanism without impacting the underlying LTS stability

- User Guide: https://docs.aws.amazon.com/linux/al2023/ug/what-is-amazon-linux.html

## Is Amazon Linux 2 build an official LTS build?
## Where can I run Amazon Linux container images?

Yes. Amazon Linux 2 end of support date (End of Life, or EOL) has been extended by two years from 2023-06-30 to 2025-06-30 to provide customers with ample time to migrate to the next version.
You can run Amazon Linux container images in any Docker based environment. Examples include, your laptop, in AWS EC2 instances, and ECS clusters.

## What packages are available in the Amazon Linux containers?

Amazon Linux Docker container images contain a subset of the packages in the images for use on EC2 and as VMs in on-premises scenarios. The container images can be configured to use any of the full set of packages in images for EC2 and on-premises use. The Amazon Linux 2 container images comes with Extras included.

## What is an Amazon Linux 2 Extra?

Extras is a new mechanism introduced in Amazon Linux 2 to enable the consumption of the newest versions of application software in a fully supported manner on a stable Amazon Linux 2 base. Extras help alleviate the compromise between stability of the OS and freshness of available software. For example, now you can install newer versions of Python being rest assured that the underlying operating system is stable. Examples of Extras include nginx, PostgreSQL, MariaDB, Go, and Rust.

## How do Amazon Linux 2 Extras work?

Extras introduces the notion of topics to select software bundles. Each topic contains all the dependencies required for the software to install and function on Amazon Linux 2. For example, Rust is an Extras topic in the curated list provide by Amazon. It provides the toolchain and runtimes for Rust, the systems programming language. This topic includes the cmake build system for Rust, cargo - the rust package manager, and the LLVM based compiler toolchain for Rust. The packages associated with each topic are consumed via the well-known yum installation process.

## How are Amazon Linux 2 Extras topics different from the packages available in yum repositories?

`yum` is a utility for package management of RPM packages. The base image of Amazon Linux 2 (LTS) includes access to repositories that already contain stable versions of popular packages that can be installed with `yum`. These packages are part of the long term support for Amazon Linux 2.

However, if you need a new software package or a newer version of an existing software package that is not included in the base Amazon Linux 2 image, Extras provide a way to install those packages in a supported manner. Extras is essentially a simplified mechanism to point yum to AWS curated sets of packages for a selected topic.

## How do I install a software package from Extras repository in Amazon Linux 2?

Available packages can be listed with the `amazon-linux-extras` command. Packages can be installed with the `amazon-linux-extras install <package>` command. Example: `amazon-linux-extras install rust1`
Amazon Linux Docker container images contain a subset of the packages in the images for use on EC2 and as VMs in on-premises scenarios. The container images can be configured to use any of the full set of packages in images for EC2 and on-premises use.

## Will updates be available for Amazon Linux containers?

Similar to the Amazon Linux images for AWS EC2 and on-premises use, Amazon Linux container images will get ongoing updates from Amazon in the form of security updates, bug fix updates, and other enhancements. Security bulletins for Amazon Linux are available at https://alas.aws.amazon.com/
