Pricing Questions for Azure Storage, FY16-17 RRS feed

  • Question

  • I noticed the prices are changing for Storage in July 2016, https://azure.microsoft.com/en-us/pricing/details/storage/

    I have the following questions:

    1. How will this be implemented? Will customer be pushed to Hot or Cold Storage?

    2. Will these price apply to storage in DWAAS and Data Lakes?

    3. Are there any best practices guides for writing queries to storage correctly in the way Microsoft intended?

    4. How is hot and cold set? Do I have to use T-SQL or Powershell?

    This has implications for a business:

    1. Scenario 1, Cold  - If customer is moved to cold, prices might be the same or less but performance will be less.

    2. Scenario 2, Hot - If customer is moved to hot, prices could be the same or less and performance would be less.

    Thanks for posting here.

    Pricing and Billing

    Blob storage accounts use a new pricing model for blob storage based on the access tier. When using a Blob storage account, the following billing considerations apply:

    • Storage costs: In addition to the amount of data stored, the cost of storing data varies depending on the access tier. The per-gigabyte cost is lower for the cool storage access tier than for the hot storage access tier.
    • Data access costs: For data in the cool storage access tier, you will be charged a per-gigabyte data access charge for reads and writes.
    • Transaction costs: There is a per-transaction charge for both tiers. However, the per-transaction cost for the cool storage access tier is higher than that for the hot storage access tier.
    • Geo-Replication data transfer costs: This only applies to accounts with geo-replication configured, including GRS and RA-GRS. Geo-replication data transfer incurs a per-gigabyte charge.
    • Outbound data transfer costs: Outbound data transfers (data that is transferred out of an Azure region) incur billing for bandwidth usage on a per-gigabyte basis, consistent with general-purpose storage accounts.
    • Changing the access tier: Changing the access tier from cool to hot will incur a charge equal to reading all the data existing in the storage account for every transition. On the other hand, changing the access tier from hot to cool will be free of cost.

     How will this be implemented? Will customer be pushed to Hot or Cold Storage?
      You will change to tier of Azure storage blobs to hot storage or cold storage.

    Will these price apply to storage in DWAAS and Data Lakes?
    Not sure, whether it implies to DWAAS and Data Lakes

     Are there any best practices guides for writing queries to storage correctly in the way Microsoft intended?
    You can write your codes as per Azure storage guidelines using API's, DML and AZCOPY.

    How is hot and cold set? Do I have to use T-SQL or Powershell?
    At the moment, it can be done using Azure Portal

    we now have support in Powershell and Azure CLI to create Blob accounts and set the tier to Hot or Cool. you can find this on the download center: https://azure.microsoft.com/en-us/downloads/
