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.
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 new EC2 A1 Arm instances are powered by the AWS Graviton Processors, featuring the 64-bit Arm Neoverse with custom silicon developed by AWS.
- 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 –
- Web Servers
- Containerized Microservices
- Caching Fleets
- Distributed Data Stores
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).
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.
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.
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.
The account setup is free, and the EC2 platform has a free trial to try period.
