New – Amazon EC2 R5b Instances Provide 3x Higher EBS Performance

In July 2018, we announced memory-optimized R5 instances for the Amazon Elastic Compute Cloud (Amazon EC2). R5 instances are designed for memory-intensive applications such as high-performance databases, distributed web scale in-memory caches, in-memory databases, real time big data analytics, and other enterprise applications.

R5 instances offer two different block storage options. R5d instances offer up to 3.6TB of NMVe instance storage for applications that need access to high-speed, low latency local storage. In addition, all R5b instances work with Amazon Elastic Block Store. Amazon EBS is an easy-to-use, high-performance and highly available block storage service designed for use with Amazon EC2 for both throughput- and transaction-intensive workloads at any scale. A broad range of workloads, such as relational and non-relational databases, enterprise applications, containerized applications, big data analytics engines, file systems, and media workflows are widely deployed on Amazon EBS.

Today, we are happy to announce the availability of R5b, a new addition to the R5 instance family. The new R5b instance is powered by the AWS Nitro System to provide the best network-attached storage performance available on EC2. This new instance offers up to 60Gbps of EBS bandwidth and 260,000 I/O operations per second (IOPS).

Amazon EC2 R5b Instance
Many customers use R5 instances with EBS for large relational database workloads such as commerce platforms, ERP systems, and health record systems, and they rely on EBS to provide scalable, durable, and high availability block storage. These instances provide sufficient storage performance for many use cases, but some customers require higher EBS performance on EC2.

R5 instances provide bandwidth up to 19Gbps and maximum EBS performance of 80K IOPS, while the new R5b instances support bandwidth up to 60Gbps and EBS performance of 260K IOPS, providing 3x higher EBS-Optimized performance compared to R5 instances, enabling customers to lift and shift large relational databases applications to AWS. R5b and R5 vCPU to memory ratio and network performance are the same.

Instance Name vCPUs Memory EBS Optimized Bandwidth (Mbps) EBS Optimized IOPs@16KiB (IO/s)
r5b.large 2 16 GiB Up to 10,000 Up to 43,333
r5b.xlarge 4 32 GiB Up to 10,000 Up to 43,333
r5b.2xlarge 8 64 GiB Up to 10,000 Up to 43,333
r5b.4xlarge 16 128 GiB 10,000 43,333
r5b.8xlarge 32 256 GiB 20,000 86,667
r5b.12xlarge 48 384 GiB 30,000 130,000
r5b.16xlarge 64 512 GiB 40,000 173,333
r5b.24xlarge 96 768 GiB 60,000 260,000
r5b.metal 96 768 GiB 60,000 260,000

Customers operating storage performance sensitive workloads can migrate from R5 to R5b to consolidate their existing workloads into fewer or smaller instances. This can reduce the cost of both infrastructure and licensed commercial software working on those instances. R5b instances are supported by Amazon RDS for Oracle and Amazon RDS for SQL Server, simplifying the migration path for large commercial database applications and improving storage performance for current RDS customers by up to 3x.

All Nitro compatible AMIs support R5b instances, and the EBS-backed HVM AMI must have NVMe 1.0e and ENA drivers installed at R5b instance launch. R5b supports io1, io2 Block Express (in preview), gp2, gp3, sc1, st1 and standard volumes. R5b does not support io2 volumes and io1 volumes that have multi-attach enabled, which are coming soon.

Available Today

R5b instances are available in the following regions: US West (Oregon), Asia Pacific (Tokyo), US East (N. Virginia), US East (Ohio), Asia Pacific (Singapore), and Europe (Frankfurt). RDS on r5b is available in US East (Ohio), Asia Pacific (Singapore), and Europe (Frankfurt), and support in other regions is coming soon.
