Azure Cold Storage is a cost-effective solution for storing large amounts of infrequently accessed data. It's designed to store data that doesn't need to be retrieved quickly.

Azure Cold Storage uses a tiered storage model, which allows you to store data in a cold storage tier when it's not actively being used. This reduces storage costs compared to hot storage.

Data is stored in a hierarchical structure, with objects in a cold storage tier being stored on slower, less expensive storage media. This allows for massive scalability and cost savings.

Azure Cold Storage is designed to be highly durable and reliable, with data replicated across multiple locations to ensure it's always available when needed.

Access

Access to your Azure Cold Storage is determined by the access tier you choose. You can select from hot, cool, or cold storage tiers.

The hot tier is ideal for data that's in active use or staged for processing. It's the best choice for data that requires frequent reads and writes. Data in the hot tier is expensive to store but cheap to access.

The cool and cold tiers are designed for less frequently accessed data. They're less expensive to store than the hot tier, but more expensive to access. Data in the cool and cold tiers has slightly lower availability, but offers the same high durability, retrieval latency, and throughput characteristics as the hot tier.

Here's a quick rundown of the access tiers:

Keep in mind that you can't change the access tier for Page Blobs, only for Append Blobs and Block Blobs.

Microsoft Accounts and Products

You can use your Microsoft account to access and manage various Microsoft products and services, including Azure.

Azure is a cloud computing platform that provides a range of services, including Azure Cold Storage.

MSP360 Explorer for Azure is a cloud explorer that lets you list, download, upload, and change the access tier of files in Azure. This tool is available for free in its standard version, making it a valuable resource for anyone looking to manage their Azure storage.

Having the ability to easily list and download files from Azure can be a huge time-saver, and the option to change the access tier of files is also a convenient feature that can help you optimize your storage costs.

Cool

The Cool tier is ideal for data that's accessed less often, but still needs to be quickly recoverable. It's about 25 percent less expensive than the Hot tier in the East US Azure region.

Data in the Cool tier can be accessed at a speed similar to the Hot tier, so you won't experience significant delays in recovering your data.

You'll pay a fee if you delete data from Cool storage within the first 30 days, known as an early deletion fee. This fee is prorated, so you'll pay for the time the data was stored in the Cool tier before deletion.

The Cool tier is a good choice for data backups that are older but still need to be quickly accessible in case of a failure.

Cool storage is guaranteed to be 99% available, which is slightly lower than the 99.9% availability of the Hot tier.

Pricing and Operations

Azure Blob Storage pricing is based on a pay-as-you-go model, where you're charged only for the resources you utilize. This means you only pay for what you use.

Data storage prices are calculated per GB per month, and the cost varies based on the different tiers where your data is stored. You can minimize costs by storing your data in the most cost-effective tier.

Reads are generally cheaper than writes, and minimizing unnecessary operations can help control costs. This is because data transfer charges apply to both uploading and downloading data, with costs influenced by data volume and transfer region.

To keep costs low, it's essential to be mindful of data transfer charges, which apply to both uploading and downloading data.

Azure offers a "lifecycle management policy" that automates the process of moving data between storage tiers.

This policy helps you avoid paying more for storage than you need, while still enforcing your organization's data backup storage policies. You can configure rules that tell Azure when to move certain pieces of data between storage tiers.

Data stored in a premium block blob storage account cannot be tiered to hot, cool, cold or archive using lifecycle management policies.

Blobs transitioned to the Archive, Cool, or Cold tiers incur early deletion periods of 180 days, 30 days, and 90 days, respectively, in addition to the per-GB, per-month charge.

Empty

In Microsoft Azure, Blob Storage is the foundation for managing and storing unstructured files. Blob Storage is a binary large object storage solution that's perfect for images, videos, music files, and backup files.

There are three ways to store Blobs in Microsoft Azure, but let's focus on the empty state of Blob Storage. An empty state is a crucial aspect of managing and lifecycle of Blob Storage.

You can create an empty container in Azure Blob Storage, which is essentially an empty folder that can hold multiple Blobs. This is a great way to organize your files and keep them separate from other containers.

An empty container is not the same as deleting a container, which removes the container and all its contents. If you delete a container, you'll need to recreate it and upload your files again.

Lifecycle Policy Management

Lifecycle policy management is a game-changer for Azure Blob Storage. It helps automate the process of moving data from one tier to another, ensuring you're not paying more for storage than you need.

You can configure rules to transition data between storage tiers based on your organization's policies. For example, you can automatically move backups to the Cool tier after seven days, keeping only a week's worth of data in Hot storage.

Azure offers a "lifecycle management policy" that simplifies this process. It's a handy feature that enforces your data backup storage policies while keeping costs in check.

Here are some key benefits of lifecycle policy management:

  • Automates the process of moving data between storage tiers
  • Helps reduce storage costs by transitioning data to lower-cost tiers
  • Enforces your organization's data backup storage policies
  • Can be configured to transition data based on specific conditions, such as data age or size

Remember, Azure lifecycle management policies can't rehydrate archived blobs to online tiers, so be sure to plan accordingly.

Comparison and Inventory

Azure cold storage offers three main tiers: Hot, Cool, and Archive. Hot storage is ideal for frequently accessed data, while Cool and Archive storage are better suited for less frequently accessed data.

The costs of these tiers vary, with Hot storage being the most expensive and Archive storage being the least expensive. If you're looking to store data for short-term backup and disaster recovery, Hot storage is a good option.

Here's a comparison of the Azure Blob Storage tiers:

Azure also offers a Blob inventory tool, which provides a comprehensive report of containers, blobs, and snapshots within your storage account. This report can be generated in CSV or Apache Parquet format, and can be used for auditing retention, legal hold, or encryption status.

Table storage is a cost-effective option for structured data and big data analysis. It's scalable and cheap to store data, making it a great choice for large datasets.

One thing to keep in mind is that access to files becomes more expensive if you frequently access them. This is because the storage is designed to be cheap for infrequent access, not for high-traffic data.

Table storage is useful if you find Azure SQL too expensive and can go without SQL structure and architecture. This makes it a great option for projects where data is not as complex.

Here are some key facts about Table storage:

Inventory

Inventory is a crucial aspect of managing your storage account, and blob inventory is a powerful tool that can help you keep track of everything. It furnishes a comprehensive inventory of containers, blobs, blob versions, and snapshots.

The blob inventory report can be generated in either CSV or Apache Parquet format, making it easy to integrate into your workflows. You can choose from daily or weekly frequency options to suit your needs.

This report serves multiple purposes, including auditing retention, legal hold, or encryption status.

You can choose from three online access tiers: hot, cool, and cold. The hot tier is ideal for data that's in active use, while the cool or cold tier is better suited for data that's accessed less frequently.

Data in the hot tier offers immediate access, making it perfect for data that requires frequent reads and writes. This tier is also great for data staged for processing and eventual migration to the cool access tier.

Here are some usage scenarios for the cool and cold access tiers:

  • Short-term data backup and disaster recovery.
  • Older data sets that aren't used frequently, but are expected to be available for immediate access.
  • Large data sets that need to be stored in a cost-effective way while other data is being gathered for processing.

Data in the cool and cold tiers have slightly lower availability, but offer the same high durability, retrieval latency, and throughput characteristics as the hot tier.
