Amazon EC2 R5 Instances

Accelerate performance for workloads that process large data sets in memory

Amazon EC2 R5 instances are the next generation of memory optimized instances for the Amazon Elastic Compute Cloud.  R5 instances are well suited for memory intensive applications such as high performance databases, distributed web scale in-memory caches, mid-size in-memory databases, real time big data analytics, and other enterprise applications. Additionally, R5d, R5dn, and R5ad instances have local storage, offering up to 3.6TB of NVMe-based SSDs.

Introducing R5n and R5dn instances

Amazon EC2 R5n and R5dn instances are the latest addition to the R5 family and provide up to 100 Gbps of networking throughput, optimized for network intensive applications.

Benefits

Flexibility and Choice

Choose between a selection of 48 different instance choices with multiple processor options (Intel Xeon Scalable processor or AMD EPYC processor), storage options (EBS or NVMe SSD), network options (up to 100 Gbps), and instance sizes to optimize both cost and performance for your workload needs.

More memory

R5 instances support the high memory requirements of certain applications to increase performance and reduce latency.  R5 instances deliver additional memory per vCPU and the largest size, r5.24xlarge, provides 768 GiB of memory, allowing customers to scale-up and consolidate their workloads on a fewer number of instances.

Maximize resource efficiency

R5 instances are powered by 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. This frees up additional memory for your workloads which boosts performance and lowers the $/GiB costs.

Features

Multiple Processor Choices

R5 and R5d instances feature the Intel Xeon Platinum 8000 series (Skylake-SP) processor with a sustained all core Turbo CPU clock speed of up to 3.1 GHz. R5 instances provide support for the Intel Advanced Vector Extensions 512 (AVX-512) instruction set, offering up to 2x the FLOPS per core compared to the previous generation R4 instances. R5n and R5dn instances feature 2nd generation Intel Xeon Scalable Processors (Cascade Lake) with a sustained all-core Turbo CPU frequency of 3.1 GHz. In additon to AVX-512, there is support for the new Vector Neural Network Instructions (AVX-512 VNNI) which will help speed up typical machine learning operations like convolution and inference. R5a and R5ad instances feature the AMD EPYC 7000 series processor with an all core turbo clock speed of up to 2.5 GHz. R5a instances offers up to 10% savings for customers who are looking to further cost optimize their Amazon EC2 compute environments.

High performance networking

R5n and R5dn instances leverage the fourth generation of custom Nitro card and Elastic Network Adapter (ENA) device to deliver up to 100 Gbps of network throughput to a single instance. These instances offer 4x the network bandwidth and packet process compared to the base R5 instances and are ideal for network intensive applications. Customers can also enable Elastic Fabric Adapter (EFA) on 24xlarge instance sizes of R5n and R5dn instances for low and consistent network latency.

High performance storage

Local NVMe-based SSD block level storage physically connected to the host server is available on all R5d, R5dn, and R5ad instances. These instances are a great fit for applications that need access to high-speed, low latency local storage including those that need temporary storage of data for scratch space, temporary files, and caches.

Built on AWS Nitro System

R5 instances are built on the AWS Nitro System, a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware. By doing so, the AWS Nitro System enables high performance, high availability, and high security while also reducing virtualization overhead.
