Amazon Elasticsearch Service UltraWarm is now generally available. UltraWarm is a performance-optimized warm storage tier that lets you store and interactively analyze your data using Elasticsearch and Kibana while reducing your cost per GB by up to 90% over hot storage options. With UltraWarm, Amazon Elasticsearch Service supports hot-warm domain configurations. Hot storage is used for indexing and providing the fastest access to data. UltraWarm complements hot storage with less expensive, more durable storage for older data that you access less frequently, all while maintaining the same interactive analysis experience.

UltraWarm amplifies the benefits of traditional hot-warm configurations. It uses a combination of Amazon S3 and optimized compute nodes powered by the AWS Nitro System to provide a hot-like experience for aggregations and visualizations. S3 provides low-cost storage with 99.999999999% (11 9's) durability, removing the need for replicas. S3 also abstracts away the notion of overhead, so each UltraWarm node can use 100% of its available storage for primary data. To improve performance, these nodes use granular caching across all layers of the stack, adaptive prefetching, and query processing optimizations to provide similar, or in many cases superior performance to traditional warm nodes which rely on high density local storage.

Previously available in preview, there are multiple enhancements introduced with UltraWarm general availability including; UltraWarm is now available in all regions Amazon Elasticsearch Service supports. We’ve added supported for UltraWarm on Elasticsearch versions 7.1 and 7.4. The limits are now increased to support up to 150 UltraWarm nodes per domain, allowing you to store 3PB of primary warm data. Additionally, UltraWarm is now integrated with the Index State Management feature so that you can automate rotating data from hot to warm as it ages. Index State Management is also now available on Elasticsearch version 6.8 and above. 

Amazon Elasticsearch Service UltraWarm is now available for domains using Elasticsearch version 6.8 and higher across 22 regions globally: US East (N. Virginia, Ohio), US West (Oregon, N. California), AWS GovCloud (US-Gov-East, US-Gov-West), Canada (Central), South America (Sao Paulo), EU (Ireland, London, Frankfurt, Paris, Stockholm), Asia Pacific (Singapore, Sydney, Tokyo, Seoul, Mumbai, Hong Kong), AWS China (Beijing, operated by Sinnet), AWS China (Ningxia, operated by NWCD), and Middle East (Bahrain) .
