Starting today, Amazon EC2 Is4gen and Im4gn instances, the latest generation storage-optimized instances, are available in Asia Pacific (Singapore) Region. Based on the AWS Nitro System, Im4gn and Is4gen instances are powered by Arm-based AWS Graviton2 processors and are build using AWS Nitro SSDs which enable up to 60% lower latency and up to 75% reduced latency variability in Im4gn and Is4gen instances compared to the third generation of storage optimized instances. Im4gn instances deliver up to 40% better price-performance and up to 44% lower cost per TB versus comparable current generation x86-based storage optimized instances for applications requiring dense local SSD storage and higher compute performance such as MySQL, NoSQL, and file systems. The Is4gen instances provide the lowest cost per TB and highest density per vCPU of SSD storage in Amazon EC2 for applications such as stream processing and monitoring, real-time databases, and log analytics, that require high random I/O access to large amounts of local SSD data. These instances enable 15% lower cost per TB of storage and up to 48% better compute performance compared to I3en instances.

These instances can utilize the Elastic Fabric Adapter (EFA) for workloads that require high levels of inter-node communication. Workloads on these instances will continue to take advantage of the security, scalability and reliability of Amazon’s Virtual Private Cloud (VPC).

Get started with Is4gen and Im4gn instances by visiting the AWS Management Console, AWS Command Line Interface (CLI), or AWS SDKs. To learn more, visit the Im4gn and Is4gen instances page.
