• Naming Storage Accounts:
  • The storage account name must be unique across all storage account names in Azure
  • The name must be between 3 to 24 characters and can contain only lowercase letters & numbers
• Replication Options:
  • Locally Redundant Storage (LRS)
  • Zone Redundant Storage (ZRS)
  • Geographically redundant storage (GRS)
  • Read access Geographically Redundant Storage (RA-GRS)
  • Geographically zone redundant storage (GZRS)
  • Read access geo graphically redundant storage (RA-GZRS)
    
• Replication options control the durability and availability of storage account
• Refer Here for the official docs
  
• SLA for storage account Refer Here
• Performance Tiers:
  • Standard:
    • This tier supports all storage services: blobs, table, files, queues.
  • Premium:
    • This tier tis designed to support workloads with greater demand on I/O and is backed by high-performance SSD disks
    • It supports
      • Page blobs
      • Block blobs
      • File Shares
• Azure Generally charges for using storage in two ways
  • Size of the storage
  • Access costs
• Access Tiers:
  • Hot:
    • used for frequently accessed objects. High Storage costs and low data access costs
  • Cool:
    • Used to store large amounts of data that is not accessed frequently. Data access costs is high and storage costs is less
    • Data should be stored atleast for 30 days
  • Archive:
    • This is used for long term storage i.e. accessed rarely
    • To access this data it will take several hours
    • Very very less price for storage
    • Data shoule be present atleast for 180 days.
• Next Steps: We will understand the pricing on what we have done so far.
