Amazon OpenSearch Service introduces support for Graviton4-based i8ge instances

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

The i8ge instances utilize the latest third-generation AWS Nitro SSDs, featuring local NVMe storage that provides up to 55% better real-time storage performance per terabyte. Additionally, these instances offer up to 60% lower storage input/output latency and up to 75% less variability in storage I/O latency compared to their predecessors, the Im4gn instances. Built on the AWS Nitro System, these instances enhance performance and security by offloading CPU virtualization, storage, and networking functions to dedicated hardware and software.

The i8ge instances are available in sizes up to 18xlarge, with instance storage reaching up to 45 terabytes. With a networking bandwidth of 112.5 Gbps, these instances boast the highest bandwidth among storage-optimized instances within Amazon OpenSearch Service. They support all versions of OpenSearch as well as Elasticsearch (open source) versions 7.9 and 7.10.

These i8ge instances are available 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).
