Optimizing Azure File Share Tiering for Your Business

Azure File Share tiering allows you to store less frequently accessed data in a lower-cost, colder storage tier, while keeping frequently accessed data in a higher-performance, hotter storage tier.

This approach can help reduce storage costs by up to 90% according to Microsoft.

You can choose from two storage tiers: Hot and Cool. Hot storage is designed for frequently accessed data, while Cool storage is designed for less frequently accessed data.

Hot storage is ideal for data that is accessed at least once a day, and Cool storage is ideal for data that is accessed less than once a month.

Azure File Share tiering also supports a third tier, Archive, which is designed for data that is not accessed for long periods of time.

The Archive tier is ideal for data that is not accessed for 180 days or more.

Azure File Share Tiering Options offer flexibility to suit different needs. Premium file shares are available through the FileStorage storage account type.

You can choose from four storage options: Premium, Transaction Optimized, Hot, and Cool. Here's a brief overview of each:

Standard file shares, on the other hand, are available in general purpose storage accounts, and pricing is based on usage.

Azure Blob storage is a great option for storing massive amounts of unstructured data. It's ideal for cloud-native workloads, high-performance computing, archiving, and data lakes/machine learning applications.

You can configure Blob storage through the Azure REST API, Azure client library, Azure CLI, or Azure PowerShell. From there, you choose one of three storage options: pay-as-you-go/on-demand pricing, reserved capacity pricing, and operations and data transfer charges.

Your payment option matters too, as it affects how you're charged for your Blob storage. Pay-as-you-go/on-demand pricing and reserved capacity pricing are the two main options.

To give you a better idea, let's break down the different storage options:

Operations and data transfer charges are also important to consider when choosing your Blob storage option.

Azure Files offers a range of storage options to suit different needs, including Premium, Transaction Optimized, Hot, and Cool file shares.

Premium file shares are ideal for highly I/O-intensive workloads, with high throughput and low latency, and are offered on high-performance solid-state drive (SSD) based storage.

You can choose between Standard and Premium storage tiers when creating a new file share based on Azure Files. The Standard tier has been renamed to Transaction Optimized, but we'll refer to it as Standard for simplicity.

The Premium tier is available through the FileStorage storage account type and is priced based on provisioned GiB, including all transaction costs. It's a great option for applications that require high performance and low latency.

Hot file shares offer storage optimized for general purpose file sharing scenarios, such as team shares, and are offered on standard storage hardware backed by HDDs.

Cool file shares provide cost-efficient storage optimized for online archive storage scenarios, such as storing infrequently accessed files.

Here's a breakdown of the main differences between the four storage options:

Azure File Sync is a service that enables on-premises Windows Server to do cloud tiering to file storage in the cloud, storing hot files locally and cool files in Azure File cloud storage.

The LRS (Locally Redundant Storage) option in Azure File Share is a cost-effective way to store data. It's designed for scenarios where data is frequently accessed and can be quickly retrieved.

Data at-rest costs for LRS are ￥ 0.250796 per used GiB for HOT data and ￥ 0.147616 per used GiB for COOL data.

Metadata at-rest costs for LRS are ￥ 0.3978 for both HOT and COOL data.

Here's a summary of the costs for LRS:

Keep in mind that these costs are specific to LRS and may vary depending on your usage and storage needs. It's essential to consider these costs when planning your Azure File Share tiering strategy.

Azure File Share is a fully managed file-sharing option in the cloud, allowing you to access your files via SMB and NFS protocols. You can mount Azure File shares concurrently in cloud or on-premises deployments of Linux, Windows, and macOS.

You can choose between the Standard and Premium storage tier when creating a new file share based on Azure Files. The Standard tier, also known as Transaction Optimized, was recently renamed, but we'll refer to it as Standard for simplicity.

Here are the key differences between the Standard and Premium storage tiers:

The price difference between Standard and Premium has dropped considerably, making Premium a more palatable option. Premium storage costs around $0.19 per GB, with pricing differing per Azure region.

Azure File Share is a cloud-based file storage solution offered by Microsoft. It's designed to store and manage files in the cloud, making it easy to access and share files across different devices and locations.

Azure File Share supports two storage tiers: Standard and Premium. Standard file shares are created in general purpose (GPv1 or GPv2) storage accounts, while Premium file shares are created in FileStorage storage accounts.

The cost of storing data in Azure File Share varies depending on the redundancy option and storage tier. For example, the cost of storing data in the Premium tier is ￥ 2.034 per provisioned GiB, while the cost of storing data in the Transaction Optimized tier is ￥ 1.4 per used GiB.

Here's a breakdown of the storage costs for Azure File Share:

Azure File Share also offers snapshot pricing, which covers the additional storage cost of differential snapshots. The cost of snapshots varies depending on the storage tier, with the Premium tier costing ￥ 1.728 per used GiB.

Azure File Share's metadata at-rest cost is included in the storage costs, except for the HOT and COOL tiers, which have a metadata at-rest cost of ￥ 0.167.

Azure File Sync is a service that enables an on-premises Windows Server to do cloud tiering to file storage in the cloud, not object storage.

Azure File Sync acts as a gateway that caches data locally and puts cold file objects in Azure File cloud storage.

The service stores hot files on the local Windows server while cool or cold files are split into namespace and file content.

The namespace is stored locally, and the file content is stored in an Azure file share in the cloud.

Azure will automatically tier cold data based on volume or age thresholds.

You can save up to 70% on on-premises storage costs with cloud tiering, but be aware of the limitations.

Azure Files is almost double the cost of Azure Blob Cool tier. This is a significant difference to consider when choosing a storage solution.

Cloud tiering can be complex, especially with multiple file server and NAS environments. Using a different tiering strategy for each environment is tedious and error-prone.

Azure Files is not resilient, so data needs replication, snapshots, and backups, leading to higher data management costs. This is a key consideration when evaluating storage options.

To maximize savings, tier files from your NAS to an object storage environment, such as Azure Blob. This will help you avoid paying higher costs in the cloud.

Here are some key differences between Standard and Premium Azure Files:

If you're using Premium Azure Files, be aware that you'll be charged for all provisioned storage, even if you're not using it. This can add up quickly.

Using cloud tiering can also help you optimize your storage costs by automating the process of storing less frequently accessed data in Cool storage and rarely accessed data in Archive storage.

Azure Files is not a suitable option for cloud tiering due to its high cost and lack of resilience.
