Understanding Azure Blob Storage Tiers

Lab Details

  1. In this lab we will get to know about what are the different access tiers in Azure Blob storage and how to work with them. 

  2. Duration: 30 minutes


What is Azure Blob Storage Tiers ?

  • Azure Storage is the Azure platform's managed service for providing cloud storage. Azure Storage is composed of several core services and supporting features. It is highly available, secure, durable, scalable, and redundant. 

  • Azure offers three storage tiers to store data in blob storage: Hot Access tier, Cool Access tier, and Archive tier. These tiers target data at different stages of its lifecycle and offer cost-effective storage options for different use cases.

  • Hot access tier :This tier should be used for the data frequently accessed by applications, and that is read or written very often. The data storage costs for this tier are higher than other tiers, but access charges are lower, thus suiting the target use case.

  • Cool access tier: This storage tier is suitable for data that is not accessed frequently by applications and is expected to be stored for a minimum of 30 days; for example, for short term storage of backup, telemetry data, media files, etc. The cost of using the cool access tier is lower than using the hot tier, however access costs and availability are not the same. 

  • Archive tier : As the name indicates, this tier is intended to be used to store rarely accessed or archival data. Its storage rate is the cheapest on Azure, but the data retrieval charges are the highest. This tier is intended as Azure archive storage for data that is expected to be stored for a minimum of 180 days and that can tolerate a larger retrieval window. The Archive tier is useful storage for large amounts of inactive data, such as data required to be stored for compliance purpose, long-term backup, archived datasets, etc.

  • These three data tiers are supported in General Purpose storage V2 and Blob storage accounts.
