Amazon EC2 R5 Instances

Fast 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 instances have local storage, offering up to 3.6TB of NVMe-based SSDs.

Benefits

Lower TCO

R5 instances are powered by the 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.

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.

Faster CPU Performance

R5 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 and support for Intel AVX-512 instructions to deliver increased CPU performance.

Features

Larger Instance Sizes

R5 instances have a 1:8 vCPU to memory ratio, with the largest size offering up to 768 GiB of memory per instance, allowing applications to scale up on fewer instances. This makes R5 instances ideally suited for applications such as high-performance databases, distributed in-memory caches, in-memory databases, and big data analytics.  

Powered by the Nitro System

R5 instances are the first memory optimized instances on the new Nitro system, which eliminates all virtualization overhead to deliver more hardware resources to your workloads. In addition, the Nitro system enables an R5 bare metal instance that allows workloads running on third-party hypervisors to seamlessly move to EC2.

Available with Instance Storage

Customers looking to further boost the performance of their workloads, such as in-memory databases, can take advantage of R5d instances with instance storage to improve memory swap performance.  R5d instances offer up to 3.6TB of NVMe-based SSDs and are available in the same sizes as R5 instances.
