With OpenSearch 2.15, you can now leverage OR1 instances for your existing Amazon OpenSearch Service domains. OR1 delivers up to 30% price-performance improvement over existing instances (based on internal benchmarks), and uses Amazon S3 to provide 11 9s of durability. You can start using OR1 by simply updating your existing domain configuration, and choosing OR1 instances for data nodes. This will seamlessly move domains running OpenSearch 2.15 to OR1 instances using a blue/green deployment. Please note that changing domain configuration from an OR1 instance type to another instance type will require a snapshot restore.
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 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 compute instance, local storage, and the managed storage. New domains can use OR1 instances with OpenSearch versions 2.11 and above and existing domains can use OR1 with OpenSearch 2.15 and above.
OR1 instance family is available on Amazon OpenSearch Service across 17 regions globally: US East (N. Virginia, Ohio), US West (Oregon, N. California), EU (Frankfurt, Ireland, London, Stockholm, Spain), Asia Pacific (Mumbai, Hyderabad, Seoul, Singapore, Sydney, Tokyo), Canada (Central), and South America (São Paulo). Please refer to the Amazon OpenSearch Service pricing page for pricing details.
