smart tier automation

Smart tier automation is a Microsoft Azure feature that continuously optimizes storage costs by automatically moving data between hot, cool, and cold tiers based on changing access patterns. Unlike traditional lifecycle rules that require manual tuning, smart tier automation runs as a managed service, making savings persistent rather than episodic. The feature is generally available in most zonal public cloud regions for Azure Blob Storage and Azure Data Lake Storage. It addresses the challenge of usage patterns evolving faster than administrators can update policies, turning storage optimization into an automatic control loop.
