Azure Blob Storage Tiers Overview
Azure Blob storage has several storage tiers that offer different performance and cost characteristics. The storage tiers available are:
- Hot: This tier is for frequently accessed data that needs to be immediately available. It is the most expensive option, but also the fastest.
- Cool: This tier is for data that is infrequently accessed, but still needs to be quickly available. It is less expensive than the hot tier, but still has good performance.
- Archive: This tier is for data that is rarely accessed and can take several hours to retrieve. It is the least expensive option, but also the slowest.
- Premium storage : this tier is for high-performance data storage for I/O-intensive workloads such as big data analytics, large-scale databases, and large-scale applications.
Customers can move data between these tiers based on their access patterns, which can help reduce costs while still meeting performance requirements.
It’s also worth mentioning that Azure Blob storage also offers the option of using the “Static Website” feature which allows you to host a static website directly out of a container in the blob storage, this feature is available in the Hot, Cool and Archive tiers.
What is the Azure Blob Storage Hot Tier?
Optimized for High Performance and Low Latency
Azure Blob Storage Hot Tier is a storage tier that provides immediate access to frequently accessed data. It is optimized for high performance and low latency and is designed for workloads that require fast and frequent access to data. The Hot tier is the most expensive option among the storage tiers, but it also provides the best performance and lowest retrieval times.
Data stored in the Hot tier is automatically replicated to ensure high availability and durability, and it can be accessed using the Azure Blob Storage API, Azure File Storage API, or Azure Data Lake Storage API.
Use cases for the Hot tier include:
- Media streaming, such as video and audio.
- Backup and disaster recovery, to quickly restore data in case of an outage.
- Big Data analytics, where fast access to data is crucial for real-time insights.
- High-performance computing, such as simulations and modeling.
It’s important to note that the Hot tier has additional charges per access and retrieval, so it’s important to evaluate if the cost is justified by the access and retrieval patterns of the data.
What is the Azure Blob Storage Cold Tier?
Optimized for Lower Cost
Azure Blob Storage Cold Tier is a storage tier that provides lower-cost storage for data that is infrequently accessed. It is designed for workloads that require quick access to data, but at a lower cost than the Hot tier. The Cold tier is less expensive than the Hot tier, but it also has slightly higher retrieval times.
Data stored in the Cold tier is also automatically replicated to ensure high availability and durability, and it can be accessed using the Azure Blob Storage API, Azure File Storage API, or Azure Data Lake Storage API.
Use cases for the Cold tier include:
- Archival data, such as backups and historical records.
- Data that is only accessed occasionally, such as log files or backups of production data.
- Cold data analytics, where the data is used occasionally for reporting or analytics.
It’s important to note that the Cold tier has additional charges per retrieval, so it’s important to evaluate if the cost is justified by the access and retrieval patterns of the data. In addition, data retrieval times may be longer for Cold Tier, so it’s important to consider the retrieval time requirement for your use case before choosing this tier.
What is the Azure Blob Storage Archive Tier?
Optimized for Long-Term Retention and Lowest Cost
Azure Blob Storage Archive Tier is a storage tier that provides the lowest-cost storage for data that is infrequently accessed and can tolerate retrieval times of several hours. It is designed for workloads that require long-term retention of data, but at a lower cost than the Hot or Cold tiers. The Archive tier is the least expensive option among the storage tiers, but it also has the longest retrieval times.
Data stored in the Archive tier is also automatically replicated to ensure high availability and durability, and it can be accessed using the Azure Blob Storage API, Azure File Storage API, or Azure Data Lake Storage API.
Use cases for the Archive tier include:
- Compliance and regulatory data, such as financial records or legal documents that need to be retained for long periods of time.
- Data that is rarely accessed, such as historical records or old backups.
- Cold data analytics, where the data is used occasionally for reporting or analytics.
It’s important to note that the Archive tier has additional charges per retrieval, so it’s important to evaluate if the cost is justified by the access and retrieval patterns of the data.
