AWS IoT SiteWise announces a new storage tier for industrial data

AWS IoT SiteWise now supports warm storage, a fully-managed storage tier that makes it easy for customers to securely store and access industrial data needed for analytics use cases such as business intelligence dashboards and machine learning applications. The warm storage tier allows customers to retain large amounts of historical data at near Amazon S3 cost per GB storage prices. Data stored in the warm tier is optimized for retrieval using AWS IoT SiteWise query API. Combined, AWS IoT SiteWise hot, warm, and cold storage tiers provide flexibility to support multiple use cases while balancing performance and cost efficiency. The hot storage tier is optimized for frequently accessed data, with low write-to-read latency for real-time applications such as interactive dashboards. The new warm storage tier is designed for cost-efficient storage of historical data, optimized for retrieving large data volumes with medium write-to-read latency. The cold storage tier uses an Amazon S3 bucket to store data that is rarely used. Customers can enable the new warm tier through the AWS IoT SiteWise storage configuration in the console or via AWS CLI. For enhanced query performance and cost efficiency, customers can define retention periods for both hot and warm storage. AWS IoT SiteWise automatically moves data between storage tiers based on the defined retention periods. This feature is available in all regions where AWS IoT SiteWise is available.
