Revision of all the Storage Aspects Covered So far

• Data Classification:
  • Structured:
    • Data that is queryable
    • Storage for this type is Databases.
    • Databases:
      • Relational
      • NoSQL
      • Document Databases
      • Graph Database
      • Cache Database
    • Message Queue Storage:
      • Queue Storage
  • UnStructured: For all unstructured storages we have Azure Storage Account.
    • Data that is not queryable
    • Storage options are
      • Block Storage => Virtual Hard disks => (Page Blob)
      • File Shares => Network Disks => Azure File Share
      • Blob Storage:
        • Any file => Block Blob
        • Log file => Append Blob
      • Data lakes: Storing Big Data/Real streaming Data etc
• Azure Storage account Redundancy:
  • LRS
  • ZRS
  • GRS
  • RA-GRS
  • RA-ZAGRS
• Storage Primary Use Cases:
  • Backup and Restore
  • Archival
• Access Tiers
  • Hot => Frequent Access => Pay more for storage and less for access
  • Cool => Infrequent Access => Pay more for access and less for storage
  • Archive => Cheaper storage for archival no access is possible.
• Terms: Hydrate and ReHydrate.
• Azure Storage Account is accessible over https, so we need to ensure who can access this. Access types
  • Anonymous (Any one can read)
  • Private (Access is given only to specific Azure users)
  • Shared Access Signature (Temporarily give access to someone to perform read/write/update/delte)

Azure Command Line Access

• Azure has two command line interfaces
  • Azure Powershell:
    • Created for Windows Admins
    • Powershell cmd-let syntax <verb>-Az<Noun>
    • To find the cmd let Get-Cmd *-Az[searchterm]
    • To Get examples and help Get-Help <cmd-let> -Online
    • In powershell we storage the output in a variable $resg = New-AzResourceGroup -Name 'Test' -Location 'Eastus'
  • Azure CLI:
    • Easier interface built for all the terminals
    • Built using python
    • Finding a command is naviagating through reference sections
    • Syntax will be in the form az service [child-service] <action> [--arg1 Value1] .. [--argn Valuen]
    • Example: az group create --name test --location 'eastus'
• We use this to auotmate the repetitive activities
