Amazon EC2 I3en Instances

I3en instances offer up to 96vCPUs of 1st or 2nd generation Intel® Xeon® Scalable processor (Skylake or Cascade Lake) with a sustained all core Turbo CPU clock speed of up to 3.1 GHz, 60 TB of total NVMe instance storage, and 768 GiB of memory. I3en NVMe instance storage can deliver up to 2 million random IOPS at 4 KB block sizes and up to 16 GB/s of sequential disk throughput, enabling workloads that need high storage capacity and random I/O performance to run more effectively on EC2.

I3en instances offer seven different instance sizes to choose from and the most NVMe SSD storage per vCPU in EC2. Reduce your cost per GB of SSD instance storage by up to 50% over I3 instances and right-size your instance selection based on workload storage requirements.

I3en instances have up to 4x the networking bandwidth of I3 instances, enabling up to 100 Gbps of sustained network bandwidth. Customers can enable Elastic Fabric Adapter (EFA) on I3en for low and consistent network latency.

I3en 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.

I3en instances offer bare metal size (i3en.metal) that provide your applications with direct access to the compute and memory resources of the underlying next generation AWS hardware and software infrastructure. Bare metal instances let you run a variety of workloads on AWS, including non-virtualized workloads, workloads that benefit from direct access to physical resources, and workloads that may have licensing restrictions. The i3en.metal instances are powered by 1st or 2nd generation Intel® Xeon® Scalable (Skylake or Cascade Lake) processors with 48 hyper-threaded cores, 768 GiB of memory, and 60 TB of NVMe SSD-backed instance storage. They deliver high networking throughput and lower latency with up to 100 Gbps of aggregate network bandwidth by leveraging the next generation of EC2 networking technology, Enhanced Networking based on Elastic Network Adapter (ENA).
