Azure Data Lake Storage pricing

Scalable, secure data lake for high-performance analytics

Azure Data Lake Storage is the world’s most productive Data Lake. It combines the power of a Hadoop compatible file system with integrated hierarchical namespace with the massive scale and economy of Azure Blob Storage to help speed your transition from proof of concept to production.

  1. Is fully integrated with the Azure Blob Storage platform; Every Blob Storage capability (Microsoft Entra ID Integration, At Rest Encryption, High-availability and disaster recovery, Automated Lifecycle Policy Management, Storage Account Firewalls, etc.) can be used by Azure Data Lake Storage.
  2. Is optimized for leading cloud analytic engines.
  3. Is tightly integrated with all elements of the Azure Big Data Analytics stack to deliver fast insights.
  4. Allows analytics data to coexist with object data in the same store with no programming changes or data copying.
  5. Performs faster than other data stores thus making your analytics workloads run faster and lowering your TCO.

Prices are estimates only and are not intended as actual price quotes. Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, and the currency exchange rate. Prices are calculated based on US dollars and converted using London closing spot rates that are captured in the two business days prior to the last business day of the previous month end. If the two business days prior to the end of the month fall on a bank holiday in major markets, the rate setting day is generally the day immediately preceding the two business days. This rate applies to all transactions during the upcoming month. Sign in to the Azure pricing calculator to see pricing based on your current program/offer with Microsoft. Contact an Azure sales specialist for more information on pricing or to request a price quote. See frequently asked questions about Azure pricing.

Azure Data Lake Storage usage is calculated in binary Gigabytes (GB), where 1 GB = 230 bytes. This unit of measurement is also known as Gibibyte (GiB), defined by the International Electrotechnical Commission (IEC). Similarly, 1 TB is 240 bytes, i.e. 1,024 GBs.

General Purpose v2 provides access to the latest Azure storage features, including Cool and Archive storage, with pricing optimized for the lowest GB storage prices. These accounts provide access to Data Lake Storage, Block Blobs, Page Blobs, Files, and Queues.

Azure Data Lake Storage provides the choice of organizing data in two different ways. With hierarchical namespaces option, customers can organize their Data Lake into structured directories, folders and files. With flat namespaces, customers can operate their Data Lake as an unstructured blob store. Regardless of the two options, customers will pay for the same storage price as per the table below. However, with the hierarchical namespace option, customers will be charged for additional meta-data associated with the folder and directory structure as part of the bill.

Cool, Cold and Archive early deletion

In addition to the per-GB, per-month charge, any blob that is moved to the Archive tier is subject to an Archive early deletion period of 180 days. Additionally, for general-purpose v2 storage accounts, any blob that is moved to the Cool tier is subject to a Cool tier early deletion period of 30 days. Any blob that is moved to the Cold tier is subject to a Cold tier early deletion period of 90 days. This charge is prorated. For example, if a blob is moved to the Archive tier and then deleted or moved to the Hot tier after 45 days, the customer is charged an early deletion fee for 135 (180 minus 45) days of storage in the Archive tier.

Data transfer prices for ADLS

When you write data into GRS accounts, that data will be replicated to another Azure region. The Geo-Replication Data Transfer charge is for the bandwidth of replicating that data to another Azure region. This charge also applies when you change the account replication setting from LRS to GRS or RA-GRS. View the Data transfer prices on Blobs pricing page.

Data Lake Storage FAQs

  • Azure Data Lake Storage is optimized for running analytic workloads on unstructured data. Azure Data Lake Storage is optimized for fast I/O of high volume data, thereby making analytic workloads run faster and lowering the TCO for analytic jobs. Further, Azure Data Lake Storage provides the added flexibility of organizing data either in a flat or hierarchical namespace.

  • With hierarchical namespaces, you can organize data into structured folders and directories. With a flat namespace, your files will be organized in a flat structure just like Blob Storage. A hierarchical namespace allows operations like folder renames and deletes to be performed in a single atomic operation, which with a flat namespace requires a number of operations proportionate to the number of objects in the structure. Hierarchical namespaces store additional meta-data for your directory and folder structure. However, as your data volume grows, hierarchical namespaces keeps your data organized and more importantly yields better storage performance on your analytic jobs – thus lowering your overall TCO to run analytic jobs.

    • Billing using flat namespaces

    Let’s say you store 120 TB of data for the whole month in Azure Data Lake Storage using flat namespaces in the “Hot Tier”. During this month, you perform 100 million operations, and let’s assume each operation is 6 MB in size. Further, let’s say that 20% of these operations are write operations and the other 80% are read operations. Finally, let’s assume you also rename 10K directories during the month.

    For flat namespaces, you will not incur additional charges for meta-data related to your files and folders and therefore will be charged for 120 TB of data. Also, since every operation is 6 MB, you will be charged two transactions per operation (4 MB + 2 MB), since every 4 MB of data read or written is charged as a transaction. Finally, directory renames are charged using a separate meter.

    This is how your total cost will be calculated:

    Resource Used Usage Volume Price Monthly Cost
    Storage 120 TB $- for first 50 TB
    $- for next 450 TB     		$- * 50 TB = $-
    $- * 70 TB = $-
    Total $-
    Transactions Writes: Every 4 MB = 2 $- per 10K 2 * $- per 10K * 20M = $-
    Reads: Every 4 MB = 2 $- per 10K 2 * $- per 10K * 80M = $-
    Total $-
    Directory Renames 10K $- per 100 $- per 100 * 10K = $-
    Total Monthly Cost:

    • Billing using hierarchical namespaces

    Let’s say you store 120 TB of data for the whole month in Azure Data Lake Storage using hierarchical namespaces in the “Hot Tier”. During this month, you perform 100 million operations, and let’s assume each operation is 6 MB in size. Further, let’s say that 20% of these operations are write operations and the other 80% are read operations. Finally, let’s assume you also rename 10K directories during the month.

    For hierarchical namespaces, you will incur additional charges for meta-data related to your files and folders and therefore will be charged for a little more 120 TB of data. Also, since every operation is 6 MB, you will be charged two transactions per operation (4 MB + 2 MB), since every 4 MB of data read or written is charged as a transaction. Finally, directory renames are charged using a separate meter.

    This is how your total cost will be calculated:

    Resource Used Usage Volume Price Monthly Cost
    Storage 132 TB $- for first 50 TB
    $- for next 450 TB     		$- * 50 TB = $-
    $- * 82 TB = $-
