Amazon EC2 A1 Instances
Optimized cost and performance for scale-out workloads
Amazon EC2 A1 instances deliver significant cost savings for scale-out and Arm-based applications such as web servers, containerized microservices, caching fleets, and distributed data stores that are supported by the extensive Arm ecosystem. A1 instances are the first EC2 instances powered by AWS Graviton Processors that feature 64-bit Arm Neoverse cores and custom silicon designed by AWS. These instances will also appeal to developers, enthusiasts, and educators across the Arm developer community. Most architecture-agnostic applications that can run on Arm cores could also benefit from A1 instances.
Take the Graviton Challenge, get up to 40% better price performance and a chance to win a trip to re:Invent 2021.
Free Trial: All new and existing AWS customers can try the t4g.micro instances free until December 31, 2021. During the free-trial period, customers who run a t4g.micro instance will automatically get 750 hours per month deducted from their monthly bill. Refer to the FAQ for additional details.
Flexibility and Choice
A1 instances add to the broadest and deepest selection of EC2 instances. Developers can now access instances with the Arm instruction set and experience the flexibility, security, reliability, and scalability of running on EC2. Familiar AWS and Amazon EC2 capabilities, such as EBS, Networking, and AMIs work seamlessly with A1 instances.
A1 instances deliver significant cost saving for workloads that are supported by the extensive Arm ecosystem. These include general purpose workloads such as web servers, containerized microservices, caching fleets, and distributed data stores that that can be spread across multiple cores and can fit within the available A1 instance memory footprint.
Maximized Resource Efficiency
A1 instances are built on the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor which delivers practically all of the compute and memory resources of the host hardware to your instances for better overall performance and security.
Powered by AWS Graviton Processors
AWS Graviton Processors feature 64-bit Arm Neoverse cores and custom silicon designed by AWS delivering optimized performance and cost. AWS Graviton Processors are built exclusively for the cloud, utilizing AWS and Annapurna Labs' expertise in running hyperscale cloud platforms and cloud applications.
High Performance Networking and Storage
Next generation Elastic Network Adapter (ENA) and NVM Express (NVMe) technology provide A1 instances with high throughput, low latency bandwidth interfaces for networking and Amazon Elastic Block Store (Amazon EBS).
Built on AWS Nitro System
The AWS Nitro System is a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware and software to deliver high performance, high availability, and high security while also reducing virtualization overhead.

Customer Success Stories
Nielsen is a global measurement and data analytics company that provides the most complete and trusted view available of consumers and markets worldwide. Nielsen has an OpenJDK based Java application that is used to collect digital data, process incoming web requests, and redirect requests based on business needs. The application is I/O intensive and scaling out in a cost effective manner is a key requirement. Nielsen seamlessly transferred this Java application to Amazon EC2 A1 instances powered by the AWS Graviton Processor.
NetEase is a leading internet technology company based in China that’s dedicated to providing premium online services centered on content, community, communication and commerce. We develop and operate some of the most popular PC-client and mobile games in China, and we have recently expanded our gaming platform into international markets. We recently switched to Amazon EC2 A1 instances with the goal of lowering our operational costs. We use Amazon EC2 A1 instances to run the audio voice service, which powers real-time player chat, and the network forwarding service, which is built to accelerate gaming traffic. “The audio voice and network forwarding services are network I/O bound and the A1 instances provide up to 10Gbps of network bandwidth. These services are written in Python which makes them platform independent and enabled a quick and easy transition to Amazon EC2 A1 instances”, says Bruce Sun, Senior Cloud Solutions Architect at NetEase Games. Bruce attributes a 40% Amazon EC2 cloud infrastructure cost saving for these services after adopting Amazon EC2 A1 instances.
"VMware is exploring running our leading virtualization platform in different Arm environments, at the Edge, on the SmartNIC, and in the Cloud. Amazon's EC2 A1 instance helps accelerate our Arm development process by providing a readily available and scalable compute instance to prototype, validate and test new use cases. The A1 metal instance also enables us to evaluate new deployment scenarios and integration with our stack which we believe will deliver meaningful innovation to our customers."

SmugMug is a service that allows users to upload, store, and share photos and videos. They achieved a 40% cost savings by migrating their photo-serving tier to EC2 A1 instances. SmugMug was able to move their software stack (PHP, Nginx, HAProxy) to A1 instances with minimal effort. And getting everything up and running on A1 instances was like any other EC2 instance for SmugMug.
Geodata processes logs of server activity for both near-real-time and long-term purposes. The processing is performed using custom software written in Python with various open-source libraries, and runs on EC2 along with other AWS technologies such as Lambda and CloudWatch Logs. Geodata found the migration of the EC2 components to EC2 A1 instances to be effortless, and the A1 instances to be optimal.
Reamp, a provider of consulting and media solutions, collects and processes data through multiple 3rd party APIs to deliver meaningful marketing insights for their customers. They seamlessly transitioned their in-house Java application using the same Ubuntu + OpenJDK software environment and found the A1 instances to deliver optimal cost and performance for their data processing workloads. Based on this positive experience with A1 instances they are currently exploring additional workloads for migration. Learn more »
