Hey there! Let's break down your existing build server specs and find the best AWS EC2 matches and alternatives for your needs:

首先，对应你ARM架构服务器的EC2实例推荐 #

Your current server uses an Ampere Altra (ARMv8.2-A) processor with 80 cores, 256GB DDR4-3200 memory, and a 4TB SATA SSD. The closest match in AWS EC2 is:

• Instance Type: m7g.20xlarge
  • CPU: 80 vCPUs based on Ampere Neoverse V1 (fully compatible with ARMv8.2-A instruction set, base clock 2.6GHz with burst up to 3.5GHz—right in line with your 3.0GHz requirement)
  • Memory: 256GB DDR4-3200, exactly matching your server's memory configuration
  • Storage: EC2 doesn't include local SATA SSD by default, but you can easily attach a 4TB EBS volume (we recommend gp3 for balanced performance and cost, or io2 if you need higher IOPS) to replicate your existing storage setup
  • Expansion: Supports PCIe Gen4-based resources like high-speed EBS and network interfaces, covering your 128 PCIe Gen4 lane needs

其他可选替代方案 #

If you need flexibility beyond the direct match, here are some other options:

• Compute-optimized ARM instance: c7g.20xlarge
  • 80 vCPUs (base clock 3.0GHz, burst up to 3.7GHz) with 160GB memory. Great if your build tasks are CPU-heavy and you can work with slightly less memory.
• Bare-metal ARM instance: m7g.metal
  • A full physical server with no virtualization overhead, offering 80 cores and 256GB memory. Ideal if you need strict hardware isolation for your build environment.
• x86-based alternative (only if your build workload is compatible): m6i.20xlarge
  • 80 x86 vCPUs with 256GB memory. A solid option if you need to switch to x86 architecture for compatibility reasons.

OS Compatibility #

All the above EC2 instances support official Ubuntu AMIs—you can find pre-built Ubuntu images directly in the AWS EC2 console or AWS Marketplace, so you won't have issues replicating your existing OS setup.
