Amazon EC2 R6i Instances
Run memory-optimized instances powered by 3rd Generation Intel Xeon Scalable processors
Amazon EC2 R6i instances are powered by 3rd Generation Intel Xeon Scalable processors and deliver up to 15% better price performance compared to R5 instances. R6i instances feature an 8:1 ratio of memory to vCPU, just like R5 instances, and support up to 128 vCPUs per instance, which is 33% more than R5 instances. These instances are SAP-Certified and are an ideal fit for memory-intensive workloads, such as SQL and NoSQL databases; distributed web scale in-memory caches, such as Memcached and Redis; in-memory databases, such as SAP HANA; and real-time big data analytics, such as Apache Hadoop and Apache Spark clusters. R6id instances come with local NVMe-based SSD block-level storage for applications that need high-speed, low-latency local storage. Compared to previous generation R5d instances, R6id instances offer 58% higher TB storage per vCPU and 34% lower cost per TB.
Amazon EC2 R6id instances now available
R6id instances are powered by 3rd Generation Intel Xeon Scalable processors with an all-core turbo frequency of 3.5 GHz, up to 7.6 TB of local NVMe-based SSD block-level storage, and up to 15% better price performance than previous generation instances. R6id are ideal for a wide range of memory-intensive workloads including those that need access to high-speed, low-latency local storage.
R6i instances deliver up to 15% better price performance than R5 instances. R6i instances also offer a new larger size with up to 128 vCPUs and 1,024 GiB of memory, letting you consolidate workloads on fewer instances and save on per-core licensing costs.
Flexibility and choice
R6i instances add to the broadest and deepest selection of EC2 instances in the cloud and provide customers 10 different instance sizes that feature varying amounts of vCPU, memory, networking, and storage. This lets customers run a broad range of memory-intensive workloads.
Maximized resource efficiency
R6i instances are built on 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 for better overall performance and security.
Powered by 3rd Generation Intel Xeon Scalable processors
R6i instances are powered by 3rd Generation Intel Xeon Scalable processors (code named Ice Lake) with an all-core turbo frequency of 3.5 GHz and include support for always-on memory encryption using Intel Total Memory Encryption (TME). R6i instances also support new Intel Advanced Vector Extension (AVX-512) instructions to run cryptographic algorithms faster.
R6i instances support 40 Gbps bandwidth to Amazon Elastic Block Store (EBS) in the largest size and up to 10 Gbps in the four smallest sizes, which is more than double that of R5 instances. R6i instances also support up to 50 Gbps networking, which is twice that of R5 instances. R6i instances provide up to 20% higher memory bandwidth per vCPU compared to R5 instances. You can also enable Elastic Fabric Adapter (EFA) on the 32xlarge and metal sizes of R6i.
Built on 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 to deliver high performance, high availability, and high security while also reducing virtualization overhead.
Amazon EC2 R6i and R6id instances are powered by 3rd Generation Intel Xeon Scalable processors and are an ideal fit for memory-intensive workloads.
