Amazon OpenSearch Service introduces support for Graviton4-based i8ge instances

Amazon OpenSearch Service has expanded its offerings by introducing support for i8ge instances, the latest generation of storage-optimized instances designed to deliver superior performance for storage-intensive tasks. These instances are powered by AWS Graviton4 processors, providing up to 60% improved compute performance compared to the previous Graviton2-based storage-optimized Im4gn instances.

The i8ge instances incorporate the latest third-generation AWS Nitro SSDs, featuring local NVMe storage that enhances real-time storage performance by up to 55% per terabyte. Additionally, they offer up to 60% reduced storage I/O latency and up to 75% lower variability in storage I/O latency compared to their predecessors, the Im4gn instances.

Constructed on the AWS Nitro System, i8ge instances offload CPU virtualization, storage, and networking functions to dedicated hardware and software. This architecture not only boosts performance but also enhances security for various workloads. The i8ge instances are available in sizes up to 18xlarge, with an instance storage capacity of up to 45 TB. They also boast the highest networking bandwidth among storage-optimized instances in the Amazon OpenSearch Service, reaching up to 112.5 Gbps.

These instances are compatible with all versions of OpenSearch and open-source Elasticsearch versions 7.9 and 7.10. The Amazon OpenSearch Service supports i8ge instances in several AWS Regions, including US East (N. Virginia), US East (Ohio), US West (Oregon), Europe (Frankfurt), Europe (Ireland), Europe (Stockholm), Asia Pacific (Malaysia), Asia Pacific (Mumbai), Asia Pacific (Singapore), and Asia Pacific (Sydney).
