Amazon OpenSearch Service introduces OR1, the OpenSearch Optimized Instance family, that delivers up to 30% price-performance improvement over existing instances in internal benchmarks and uses Amazon S3 to provide 11 9s of durability. The new OR1 instances are best suited for indexing-heavy workloads, and offers better indexing performance compared to the existing memory optimized instances available on OpenSearch Service. 

With OR1, we have rearchitected the OpenSearch Service managed clusters storage system to leverage best-in-class cloud technologies like Amazon S3, to provide higher durability, and improved price-performance. OR1 enables customers to economically and reliably scale their OpenSearch deployments without compromising the interactive analytics experience they expect. Each OR1 instance is provisioned with compute, local instance storage for caching, and remote Amazon S3-based managed storage. OR1 offers pay-as-you-go pricing and reserved instances, with a simple hourly rate for the instance, local instance storage, as well as managed storage provisioned. OR1 instances come in sizes ‘medium’ through ‘16xlarge’, and offer compute, memory, and storage flexibility. OR1 instances support OpenSearch versions 2.11 and above. Please refer to the Amazon OpenSearch Service pricing page for pricing details.

OR1 instance family is now available on Amazon OpenSearch Service across 12 regions globally: US East (N. Virginia, Ohio), US West (Oregon, N. California), EU (Ireland, Frankfurt, Stockholm, Spain), and Asia Pacific (Singapore, Sydney, Tokyo, Mumbai). Please refer to the AWS Region Table for more information about Amazon OpenSearch Service availability.
