Azure Storage Account

Redundancy

• Redundancy: This is about multiple copies of the data maintained by azure internally Refer Here
  • LRS (Locally redundant storage) : Refer Here
    
  • ZRS (Zone Redundant storage): Refer Here
    
  • GRS (Geo-Redundant Storage): Refer Here
    
  • GZRS (Geo-zone-redundant storage): Refer Here
    
• Synchronous Replication: Upload is not completed until all the replications are completed (LRS, ZRS) and Asynchronous Replication: Upload is done asynchronous i.e. upload is shown as completed during replication primary copy to secondary copy.

Performance

• Azure Storage accounts has different types of storage accounts on the basis of two primary factors
  • Standard: They are used for general purpose, with each storage account serving
    • blob storage
    • Table Storage
    • File share
    • Queue Storage
  • Premium: For low latency solutions premium is used. Premium Blobs support only LRS or ZRS. Premium storage accounts have
    • Premium blob blobs
    • Premium file share
    • Premium page blob
