Definition
ARM-AMI refers to Amazon Machine Images (AMIs) built for EC2 instances running on ARM-based processors (Graviton/Graviton2/Graviton3). These AMIs are optimized for ARM architecture and offer better price-performance ratio compared to x86 AMIs for many workloads.
Key Characteristics
- Architecture: ARM64 (AArch64), based on AWS Graviton processor family
- Performance: Better price-performance for many workloads (web servers, containers, microservices)
- Cost: Lower licensing costs (no x86 licensing fees)
- Availability: Available for Amazon Linux, Ubuntu, RHEL, and other supported OSes
- Shared Infrastructure: AMIs, EBS volumes, and KMS keys shared across all organization accounts
AMI Roadmap Context
Per ctp-topic-50-ami-roadmap-for-aws-amis, the ARM-AMI roadmap milestones:
- November 2022: RHEL 9 ARM planned
- May 2023: RHEL 9.4 ARM and Ubuntu 22.04 ARM
- Starting May 2023: All ARM processors related to AMIs are released synchronously
The ordering of ARM AMI releases is primarily driven by ADM (Architecture Decision Management) requirements.
