This product has charges associated with it for seller support. A high-performance CentOS Stream AMI for ARM64 (Graviton), equipped with a 64K page size kernel to maximize memory throughput. Featuring UEFI and GPT, it is the ideal foundation for memory-intensive enterprise workloads and large-scale data processing.
Overview
This is a repackaged open source software product wherein additional charges apply for extended support.
This product is an AWS AMI (Amazon Machine Image) built upon CentOS Stream, the upstream development platform for Red Hat Enterprise Linux (RHEL). It is designed to provide a stable, secure, and future-ready operating system for mission-critical cloud workloads.
Modern Boot & Storage Optimization This image utilizes UEFI booting combined with a GPT (GUID Partition Table). This modern configuration ensures maximum performance on AWS Nitro-based instances and provides full out-of-the-box support for high-capacity storage volumes exceeding 2TB.
Clean & Minimal Foundation This AMI is a "Minimal" distribution, containing only the essential packages required for system operation and security. This reduces the attack surface and ensures a lightweight footprint, allowing you to install only the specific software your business requires.
4K vs 64K Kernel Page Size On ARM64 CentOS, the kernel can use 4K or 64K pages. 4K is the default, ensuring broad compatibility with applications and drivers, making it suitable for general-purpose servers. 64K reduces page counts for large memory workloads, improving efficiency in areas like big data, HPC, or in-memory databases, though it may cause compatibility issues. In short, 4K fits most deployments, while 64K benefits specialized, memory-intensive tasks.
Key Features
- Multi-Architecture Support: Fully optimized for both Intel/AMD (x86_64) and AWS Graviton (ARM64) processors.
- Cloud-Ready Integration: Pre-installed with AWS Systems Manager (SSM) Agent for secure, automated instance management.
- Enterprise Security: Hardened system configurations with the firewall disabled by default to allow for flexible Security Group management.
- Automatic Scaling: Root partitions and filesystems (Ext4/XFS) are configured to automatically expand upon launch if a larger EBS volume is specified.
- Flexible Disk Layouts: Offers a variety of filesystem (Ext4/XFS) and partition (LVM/Standard) combinations to match your workload requirements-ensure to check the Product Title for the specific version details.

Amazon Machine Image (AMI)
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.
