Azure Storage Account

• Azure Storage Account supports the following storage options
  • Blob Storage: This supports three different types of blobs
    • Block Blob: Any file with size less than 4.7 TiB
    • Page Blob: This is virtual hard disk storage (not recommended anymore)
    • Append Blob: This is used to store log files.
  • Azure File Share
  • Table Storage
  • Queue Storage
  • Data lakes
• You can work with storage account as if the the size is unlimited.
• Azure storage account should have unique name across azure.

Creating a Storage Account

• Steps:
  • Create a resource group
    
    
    
  • Create a storage account
    
    
    
    
  • Create a container
    
    
    
  • Now upload any images into the container
    
  • Now select any image uploaded and copy url
    
  • Now open this url in any browser
    
  • Lets look at the url for pattern
    https://qtstoragedemo.blob.core.windows.net/images/azstorage1.png
=> https://<storage-acc-name>.blob.core.windows.net/<container-name>/<blob-name>
  • The storage account name has to be unique to match the url and resolve different storage accounts
  • When we created the container we have selected anonymous blob acccess to ensure any one with link of the blob can access using open internet.

Azure Storage account – Concepts

• Pricing: Azure charges for the usage of storage account in terms of
  • size
  • data transfers
• Access Tier: Azure storage costs will be two fold. cost for storage of data in storage account and cost for accessing (data transfer). There are three options
  • Hot tier:
    • This represents files which are accessed frequently
    • In this case the storage cost is more and access cost is less
  • Cool tier:
    • This represents files which are accessed rarely
    • In this case the storage cost is less and access cost is more
  • Archive tier:
    • This represents archival data. Here there is no way to access the data
    • Storage cost is extreemly low
    • If you want to access archive tier convert the data from archive tier to cool/hot

Understanding costs based on access tier

• For Azure Pricing calculator Refer Here
• Scenario 1:
  • Storage size = 1 TB
  • Data is frequently accessed by approximately 10,000 users
  • Hot tier
    
    
  • Cool tier
    
  • Archive tier: we cannot access the data
    
• Scenario 2:
  • Storage size = 1 TB
  • Data is accessed by 1 user
  • Hot tier:
    
  • Cool tier
