CentOS 8 on AWS EC2

Overview:

Ready to use minimal CentOS 8 AMI. Login using 'centos' user and ssh public key authentication. Root partition and filesystem extends automatically during boot if instance volume is bigger than the default 8 GiB one. This CentOS 8 AMI has cloud-init included. In this CentOS 8 image ENA is enabled. All CentOS 8 security updates available at the release date are included.

Highlights:

This image is built using CentOS 8 'Minimal Install' group of packages. It contains just enough software to run within AWS, start an SSH server, and allow users to log in securely. Cloud-init is also included, enabling automated instance initialization tasks such as configuring users, SSH keys, networking, and other launch-time customization commonly used in cloud environments.
In this CentOS8 AMI, the root partition and filesystem automatically expand during boot whenever the attached instance volume is larger than the default 8 GiB size. This allows the system to make use of the additional storage capacity without requiring manual partitioning or resizing steps after launch. The image uses GPT (GUID Partition Table), which supports volumes larger than 2 TiB and offers a more modern and flexible partitioning scheme for larger cloud environments.
All our CentOS Stream 8 images come with Enhanced Networking enabled through ENA (Elastic Network Adapter), helping deliver improved network throughput, lower latency, and better overall network performance. SELinux is enabled as well, adding an extra layer of security through mandatory access controls. In addition, all security updates available at the image release date are already included, helping provide a more secure and up-to-date starting point from first launch.
