Azure Storage

Storage Replication options – 4LZGRaG

  1. Locally Redundant (Standard_LRS) – 3 data copies in single facility in a single location
  2. Zone Redundant (Standard_ZRS) – 3 data copies in two or three facilities in a single location (BLOB only)
  3. Geo-Redundant (Standard_GRS) – LRS + 3 data copies stored in a secondary location (most resilient)
  4. Read-Access Geo-Redundant (Standard_RAGRS) – Same as GRS but at a failover state the data in   secondary location is Read Only

Types of Storage – 4BTQF

  1. BLOB Storage – Binary Large Objects; any type of file or binary data; Storage for storing unstructured data. E.g., Documents, images, videos, logs files, VM Disks (vhd)
  2. Table Storage – Tables to store data; these tables have no schema, developers can use table storage to develop based on fast changing requirements.
  3. Queue Storage – Distributed applications need to communicate asynchronously. Queueing is one mechanism for such communication.
  4. File Storage – It is like a file share; SMB share. Can be mapped using a network drive

Types of blob Storage 3BAP

  • Block blobs are optimized for streaming and storing cloud objects, and are a good choice for storing documents, media files, backups etc.
  • Append blobs are similar to block blobs, but are optimized for append operations. An append blob can be updated only by adding a new block to the end. Append blobs are a good choice for scenarios such as logging, where new data needs to be written only to the end of the blob.
  • Page blobs are optimized for representing IaaS disks and supporting random writes, and may be up to 1 TB in size. An Azure virtual machine network attached IaaS disk is a VHD stored as a page blob.
