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.
R8gn instances, featuring 6th generation AWS Nitro Cards, offer up to 600 Gbps of network bandwidth, the highest network bandwidth among network optimized EC2 instances. These new instances are ideal for running network-intensive SQL and NoSQL databases, and in-memory databases.
The new Amazon EC2 R8gb instances offer higher EBS performance compared to same-sized R8g instances. R8gb instances deliver up to 150 Gbps bandwidth and 720K IOPS of EBS performance. These instances are ideal for workloads requiring high block storage performance such as high performance databases and NoSQL databases.
AWS Graviton4-based Amazon EC2 R8g Instances
Benefits
High performance
R8g instances deliver up to 30% better performance over Graviton3-based R7g instances. R8g 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.
R8gn and R8gb instances include DDR5-6400 memory. R8gn instances are ideal for running network-intensive SQL and NoSQL databases, and in-memory databases. R8gb instances are ideal for high performance databases and NoSQL databases that require high block storage performance.
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.

Customer testimonials
Here are examples of how customers and partners have achieved their business agility, price performance, cost savings, and sustainability goals with Amazon EC2 R8g instances.
Honeycomb
Read the detailed honeycomb Graviton4 blog to learn more.
"We started our AWS Graviton journey four years ago in 2020. With AWS Graviton4-based Amazon EC2 R8g instances, we've now achieved more than double the throughput per vCPU compared to the non-Graviton based instances that we used four years ago. "
Liz Fong-Jones, Field CTO, honeycomb.io
ClickHouse
Watch Uncovering the Real-World Performance of AWS Graviton4 with ClickHouse video to learn more.
" 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."
Alexey Milovidov, CTO and Co-Founder, ClickHouse
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. "

Datadog
Epic
"AWS Graviton4-based Amazon EC2 R8g instances are the fastest Amazon EC2 instances we've ever tested, and they are delivering outstanding performance across our most competitive and latency sensitive workloads. "We look forward to using Graviton4 to improve player experience and expand what is possible within Fortnite."
Roman Visintine, Lead Cloud Engineer, Epic Games
SAP
"In November of last year, we announced that SAP HANA Cloud was live on AWS Graviton-based instances, leading to a 35% price performance improvement for analytics workloads, and an estimated 45% reduction in carbon footprint for SAP HANA Cloud. SAP will be using AWS Graviton4-based Amazon EC2 instances for SAP HANA Cloud and additional SAP applications. Initial results for AWS Graviton4-based Amazon EC2 R8g instances with SAP HANA Cloud show up to 25% performance improvement for analytical and up to 40% improvement for transactional workloads compared to AWS Graviton3-based instances. We have also expanded the use of AWS Graviton-based instances across services in SAP BTP, and based on SAP HANA Cloud using it to power services including SAP Datasphere, and SAP CloudALM."
Sprinklr
Sprinklr is the unified platform for customer-facing functions, helping brands turn public conversations on modern channels into valuable insights. Sprinklr leverages advanced proprietary AI to help enterprises become human at scale across 30+ digital and social channels.
"As an early adopter of AWS Graviton-based Amazon EC2 instances, Sprinklr has seen tremendous value in upgrading to AWS Graviton4-based Amazon EC2 R8g instances. The transition from previous generation Graviton-based instances was seamless—taking just a few days—and we're now seeing 15-25% performance gains across our Java-based microservices running on Amazon EKS. Our experience with AWS has been great, with timely support and early access to preview upcoming instance types that help us stay ahead of our infrastructure needs."
