Why Amazon EC2 R7g Instances?
Amazon Elastic Compute Cloud (EC2) R7g instances, powered by the latest generation AWS Graviton3 processors, are designed for memory-intensive workloads. R7g instances are ideal for memory-intensive workloads such as open-source databases, in-memory caches, and real-time big data analytics. They offer up to 25% better performance over the sixth-generation AWS Graviton2-based R6g instances. R7g instances feature Double Data Rate 5 (DDR5) memory, which provides 50% higher memory bandwidth compared to DDR4 memory to enable high-speed access to data in memory.
R7g instances are available with a local NVMe-based SSD block-level storage option (R7gd) for applications that need high-speed, low latency storage. R7gd instances have up to 45% better real-time NVMe storage performance than comparable Graviton2-based instances.

Benefits
R7g instances deliver up to 25% better performance over Graviton2-based R6g. They are ideal for memory-intensive applications, such as open-source databases, in-memory caches, and real-time big data analytics.
R7g 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 multi-tenancy, private networking, and fast local storage. AWS Graviton3 processors offer enhanced security with always-on memory encryption, dedicated caches for every vCPU, and support for pointer authentication. These instances also support encrypted Amazon Elastic Block Store (EBS) volumes by default.
AWS Graviton-based instances are supported by many Linux operating systems, including Amazon Linux 2, Red Hat Enterprise Linux, SUSE, and Ubuntu. 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 partner software vendors that you can use on AWS Graviton-based instances.
Features
AWS Graviton3 is the latest generation of AWS-designed Arm-based processors that provide great price performance for workloads in Amazon EC2. AWS Graviton3 processors deliver up to 25% better compute performance, up to 2x higher floating-point performance, and up to 2x faster cryptographic workload performance compared to AWS Graviton2 processors. Additionally, Graviton3 processors deliver up to 3x better performance compared to Graviton2 processors for ML workloads, including support for bfloat16.
R7g instances use leading edge DDR5 memory to provide 50% higher bandwidth compared to R6g. R7g instances are also available with local instance storage option (R7gd). R7g and R7gd instances have support for Elastic Fabric Adapter (EFA) in the 16xlarge and bare-metal sizes.
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, reducing virtualization overhead.
