Designed for I/O intensive workloads and equipped with super-efficient NVMe SSD storage, these instances can deliver up to 3.3 million IOPS at a 4 KB block and up to 16 GB/second of sequential disk throughput. This makes them a great fit for any workload that requires high throughput and low latency including relational databases, NoSQL databases, search engines, data warehouses, real-time analytics, and disk-based caches. When compared to the I2 instances, I3 instances deliver storage that is less expensive and more dense, with the ability to deliver substantially more IOPS and more network bandwidth per CPU core
