Amazon EC2 I3 Instances

Storage optimized for high transaction workloads

Amazon EC2 I3 instances are the next generation of Storage Optimized instances for high transaction, low latency workloads. I3 instances offer the best price per I/O performance for workloads such as NoSQL databases, in-memory databases, data warehousing, Elasticsearch, and analytics workloads. I3 Instances offer the EC2 Bare Metal instance type for non-virtualized workloads, license-restricted workloads, and virtualized workloads running on your own hypervisor.



High performance storage

Amazon EC2 I3 instances include Non-Volatile Memory Express (NVMe) SSD-based instance storage optimized for low latency, very high random I/O performance, and high sequential read throughput, and deliver high IOPS at a low cost. I3 instances offer up to 25 Gbps of network bandwidth and up to 9 Gbps of dedicated bandwidth to Amazon Elastic Block Store (Amazon EBS).

Bare Metal Instances (Preview)

I3 instances offer a Bare Metal instance type (i3.metal) that provides your applications direct access to the compute, memory and networking 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, virtualized workloads using your own hypervisor, and custom and business critical applications that have license restrictions. The i3.metal instances are powered by Intel Xeon E5-2686 v4 (Broadwell) processors with 36 hyperthreaded cores, 512 GiB of memory, and 15.2TB of NVMe SSD-backed instance storage. They deliver high networking throughput and lower latency with up to 25 Gbps of aggregate network bandwidth by leveraging the next generation of EC2 networking technology, Enhanced Networking based on Elastic Network Adapter (ENA).
