Amazon EC2 R8g Instances

Best price performance for memory-intensive workloads in Amazon EC2

Why Amazon EC2 R8g Instances?

Amazon Elastic Compute Cloud (Amazon EC2) R8g instances, powered by the latest-generation AWS Graviton4 processors, provide the best price performance in Amazon EC2 for memory-intensive workloads. Amazon EC2 R8g instances are ideal for memory-intensive workloads, such as databases, in-memory caches, and real-time big data analytics. R8g instances offer up to 30% better performance and larger instance sizes with up to 3x more vCPUs and memory than the seventh-generation AWS Graviton3-based R7g instances. R8g instances are also available with a local NVMe-based SSD block-level storage option (R8gd) for applications that need high-speed, low latency storage.

Benefits

High performance

R8g instances deliver up to 30% better performance over Graviton3-based R7g instances. These instances include DDR5-5600 memory and are ideal for a large number of workloads, such as databases, in-memory caches, and real-time big data analytics.

Maximized resource efficiency

R8g instances are built on the AWS Nitro System. The AWS Nitro System is a combination of dedicated hardware and a lightweight hypervisor that delivers isolated multitenancy, private networking, and fast local storage.

Extensive software support

AWS Graviton-based instances are supported by most popular Linux operating systems. Many popular applications and services for security, monitoring and management, containers, and continuous integration and delivery (CI/CD) from AWS and software partners also support AWS Graviton-based instances. The AWS Graviton Ready program offers certified solutions from AWS Partner software vendors that you can use on AWS Graviton-based instances.

Features

Powered by AWS Graviton4 processors

AWS Graviton4 is the latest generation of server processors designed by AWS that provide the best performance and energy efficiency for workloads in Amazon EC2. AWS Graviton4 processors deliver up to 30% better compute performance than Graviton3 processors.

Enhanced security

AWS Graviton4 processors offer enhanced security with always-on memory encryption, dedicated caches for every vCPU, and support for pointer authentication. R8g instances also support encrypted Amazon Elastic Block Store (Amazon EBS).

Built on the 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. It delivers high performance, high availability, and high security, thus reducing virtualization overhead.

" As the provider of ClickHouse Cloud, a serverless real-time data warehouse, speed is deeply important, as is improving the price performance ratio of our managed service. Since the release of AWS Graviton-based Amazon EC2 instances, we have worked through the transition by building Arm architecture compatibility into our open source packages and ensuring all dependencies were met. We have been running AWS Graviton4-based Amazon EC2 R8g instances in staging environments, internal benchmarks, and as a test platform for applications (ADS-B visualization). We see that R8g instances have the potential to provide up to a 20% better price performance. We expect broad deployment of R8g instances across the control plane and data plane of the ClickHouse Cloud infrastructure."

Recruit Co., Ltd.

Recruit Co., Ltd. operates matching and solutions business under the Recruit Group. As a subsidiary under Recruit, Quipper provides educational services such as online learning platforms, educational information sites, and support for schools.

"We regularly experience spikes in traffic, and we are always looking for ways to improve performance while decreasing the cost of running our database workload on MongoDB. We evaluated Amazon EC2 R8g instances in one of our production workloads. The migration to R8g instances from AWS Graviton2-based instances took a few hours, without any code changes. We've found that the CPU load per request decreased by about 50% compared to Graviton2-based instances. This translates to approximately 2x better price performance compared to Graviton2, based on on-demand usage. We plan to expand our usage of Graviton instances in the near future. "

SmugMug

"At SmugMug and Flickr, we’re committed to delivering fast and efficient services to our photographer customers. As the first adopter of AWS Graviton-based Amazon EC2 instances in 2018, we’ve experienced years of cost savings and performance gains from AWS Graviton. Each generation of Graviton-based instances has unlocked higher levels of price/performance. These generational improvements grew faster than comparable non-Graviton instances, resulting in higher compound growth in our advancements. For image and data compression operations, we’ve measured 20 to 40% performance and capacity improvements using Graviton4-based instances compared to Graviton3-based instances."
