Description

Introducing smart tier Public Preview for account level tiering 

Announcing the public preview of smart tier for Azure Blob Storage and Azure Data Lake Storage (ADLS). Smart tier is a fully managed and automated data tiering solution, avoiding manual tier placement for object storage standard online tiers. 

Smart tier automatically moves your data between hot, cool, and cold access tiers based on usage patterns, optimizing your costs for these access tiers automatically. New data is stored in the hot tier. Any object that isn’t accessed for 30 days is moved to the cool tier; after 90 days of inactivity, it transitions to the cold tier. If objects are accessed, they are transitioning back to the hot tier and restart their tiering cycle. 

Key Capabilities 

  • Seamless Enablement: Activate smart tier at the storage account scope on new and existing general purpose v2 storage accounts with zonal redundancies today.  
  • Automated Lifecycle: Data movement between tiers is fully automated. Smart tier ensures optimal tier placement for both your active and inactive objects.
  • Simplified Billing Model: Your data uses the existing hot, cool and cold tier capacity prices. There are no charges for tier transitions inside smart tier, early deletion or data retrieval fees. A monitoring fee Is charged for objects stored in smart tier over 128 KiB in size.
