Amazon OpenSearch Service now offers a new multi-tier storage

Amazon OpenSearch Service now offers a new multi-tier storage option powered by OpenSearch Optimized Instances. This new architecture combines Amazon S3 cloud technology with local instance storage to deliver improved durability and performance. The new multi-tier architecture features two tiers: hot and warm. The hot tier handles frequently accessed data, while the warm tier leverages Amazon S3 for cost-effective storage of less frequently accessed data.

Until now, Amazon OpenSearch Service supported a warm tier through UltraWarm, which provided cost-effective storage for read-only data. The new warm tier powered by OpenSearch Optimized instances supports write operations, providing greater flexibility for data management. You can automate rotating data from hot to warm as it ages using Index State Management feature.

For warm tier deployments, customers can use OpenSearch Optimized (OI2) instances (size ‘large’ to ‘8xlarge’), with addressable warm of up to five times the local cache size. tandard Managed Storage charges apply for warm data. The new Multi-tier experience is available on OpenSearch 3.3 and above. For more information please refer to the documentation.

New Multi-Tier experience on OI2 instance family is now available on Amazon OpenSearch Service across 12 regions globally: US East (N. Virginia, Ohio), US West (Oregon), Canada (Central), Asia Pacific (Mumbai, Singapore, Sydney, Tokyo), Europe (Frankfurt, Ireland, London, Spain).
