A1 ARM Instances
Amazon had first released its 64-bit ARM EC2 A1 Instances back in 2018, which are part of AWS Elastic Compute Cloud (EC2), an ever-evolving virtual platform that supports business subscribers utilizing applications in the cloud.
Arm Bare Metal Instances
The most recent launch is the EC2 A1 ARM Bare Metal Instances, which Amazon is reporting is similar to the previous version of A1 ARM Instances, but with greater reach within the ARM ecosystem.
The Servers
The new EC2 A1 Arm instances are powered by the AWS Graviton Processors, featuring the 64-bit Arm Neoverse with custom silicon developed by AWS.
Features Include
-
- Amazon Machine Images (AMI)
- Elastic Block Store (EBS)
- Auto Scaling
Applications can have more direct access to the processor and memory resources within the underlying server. Some of the different types of scale-out applications the new Instances support and will enhance are –
Application Types
-
- Web Servers
- Containerized Microservices
- Caching Fleets
- Distributed Data Stores
A1 Arm Bare Metal Instance
The EC2 A1 ARM Bare Metal Instances offer alternative to existing Intel Xenon Scalable processors instances such as m5.metal, m5d.metal, r5.metal, r5d.metal, and z1d.metal.
The new a1.metal instance comes with 16 logical Arm processors, 32GB memory, 3.5 Gbps EBS-optimized bandwidth, and up to 10 Gbps network bandwidth.
It’s available now in in US East (N. Virginia), US East (Ohio), US West (Oregon), Europe (Ireland), Europe (Frankfurt), Asia Pacific (Tokyo), Asia Pacific (Mumbai), and Asia Pacific (Sydney).
Bare Metal Environments
The term Bare Metal is referring to the metal in a hard disk, which is the usual medium where an OS is stored. The Bare Metal environment is virtual machine instances that are installed directly onto the hardware, rather than within the software of the host OS.
How Bare Metal Works
The user rents hardware resources from the remote provider, which affords greater flexibility – for high-transaction and big-data applications, which don’t tolerate latency.
How AWS EC2 Billing Works
AWS offers to price based on what service you need and how you will use that service. EC2 is offered the billing options of, On-Demand, Spot Instances, Reserved Instances, and Dedicated Host, and also Per-second Billing.
AWS EC2 Account Setup
The account setup is free, and the EC2 platform has a free trial to try period.

“The term Bare Metal is referring to the metal in a hard disk, which is the usual medium where an OS is stored”
I don’t think that’s correct. Just as big iron refers to mainframes and little tin refers to blades or rackmount servers, ‘metal’ refers to physical hardware but not specifically to the hard drive.
The next bit is right though, bare metal is a dedicated server that does not use virtualisation. Your desktop PC also runs ‘bare metal’.
Agreed, for me “bare metal” has always meant “running direcly on the silicon” as opposed to having some software imposed between your code and the silicon.
As far as I know the original AWS Graviton is not Neoverse since it’s based on Cortex-A72.
Could that mean that new instances are now running with A76 chips?
AWS Graviton is Neoverse Cosmos (CA72 or CA75).
