Today, we are announcing the general availability of storage-optimized Amazon EC2 I3en instances, the largest Non-Volatile Memory Express (NVMe) based SSD storage instance in the cloud. I3en instances offer up to 60 TB of low latency NVMe SSD instance storage and up to 50% lower cost per GB over I3 instances. These instances are designed for data-intensive workloads such as relational and NoSQL databases, distributed file systems, search engines, and data warehouses that require high random I/O access to large amounts of data residing on instance storage. I3en instances also provide up to 100 Gbps of networking bandwidth, up to 96 vCPUs, and up to 768 GiB of memory. In addition, customers can enable Elastic Fabric Adapter (EFA) on I3en for low and consistent network latency. I3en instances are powered by AWS-custom Intel® Xeon® Scalable (Skylake) processors with 3.1 GHz sustained all core turbo performance.
I3en instances come in seven instance sizes, with storage options from 1.25 to 60 TB. I3en instances deliver up to 2 million random IOPS at 4 KB block sizes and up to 16 GB/s of total disk throughput at 128 KB block sizes. These instances are available today in US East (N. Virginia), US West (Oregon), and Europe (Ireland) AWS regions.
Amazon EC2 I3en instances are offered as On-Demand, Reserved, or Spot Instances. For pricing, visit the EC2 pricing page. For details and to get started visit the Amazon EC2 I3en page, AWS Management Console, AWS Command Line Interface (CLI), or AWS SDKs.
