Understanding Azure Storage

• Azure Storage gives us a very scalable and highly available solution.
• You can store hundreds of TB of data and you pay for the storage used
• Why should we use Azure Storage
  • Global Presence
  • Redundancy & Recovery
  • Many flavors
  • Pay as you go.

Azure Storage Types

• Azure has many types & sub types of Storage.
• The most common types of azure Storage can be classified on the following factors

  • Durability (replication):

    • Azure Storage is durable & supports data replication; therefore you make sure your storage is highly available
    • Replication ensures your data is copied somewhere else (in same datacenter, different datacenter, different region)
    • Refer Here for SLA Details
    • Replication Types:
      • Locally redundant Storage (LRS):
      • Zone redundant Storage
      • Geo-Redundant Storage (GRS)
      • Read-access geo redundant storage (RA-GRS): data i.e. replicated to other region will have Read access

  • Performance:

    • Standard Storage:
      • This stores the data in non-SSD Disks
    • Premium Storage
      • This is designed for applications which require low latency for storage. Premium storage is stored on SSD disks

  • Persistency: This is all about whether data will be persisted (present) when your vm is stopping & starting

    • Persistent Storage
    • Non-Persistent Storage

Azure Storage Account

• This is a service that provides access to azure storage.
• Each storage account should have unique name
• Creating a Storage Account
  • Create a resource Group
  • Create a storage account
