Amazon OpenSearch Service introduces support for Graviton4-based i8ge instances

Amazon OpenSearch Service has announced support for i8ge instances, marking the introduction of the latest generation of storage-optimized instances designed for high-performance storage-intensive tasks. These instances are powered by AWS Graviton4 processors, offering up to 60% improved compute performance over the previous Graviton2-based Im4gn instances.

The i8ge instances utilize third-generation AWS Nitro SSDs with local NVMe storage. This configuration provides up to 55% better real-time storage performance per terabyte, while also achieving up to 60% lower storage I/O latency and up to 75% reduced variability in storage I/O latency compared to the earlier Im4gn instances. Built on the AWS Nitro System, these instances offload CPU virtualization, storage, and networking functions to dedicated hardware and software, thereby enhancing both performance and security for various workloads.

Available in sizes up to 18xlarge with 45 TB of instance storage, the i8ge instances offer the highest networking bandwidth among storage-optimized instances within Amazon OpenSearch Service, reaching up to 112.5 Gbps. These instances are compatible with all OpenSearch versions as well as open-source Elasticsearch versions 7.9 and 7.10.

The i8ge instances are currently supported in multiple AWS Regions, including US East (N. Virginia), US East (Ohio), US West (Oregon), Europe (Frankfurt), Europe (Ireland), Europe (Stockholm), and Asia Pacific regions such as Malaysia, Mumbai, Singapore, and Sydney.
