AZ-104 Azure - Configuring blobk object replication

• Object replication configuration
• Object replication overview

Object replication asynchronously copies blocks of blobs between storage accounts

• • Requires source and destination storage accounts 
    
  • Requires versioning and change feed
  • Support cross-tenant replication

 

• Minimize latency - reduce latency for read requests.
• Increased efficiency - Processing block blob in different regions.
• Data distribution - Processing and analyzing data in one location that replicate to other regions.
• Cost Optimization -moving replicate data to the archive tier can reduce cost.

 

• Versioning: Versioning must be enabled on both the source and desalination accounts to perform replication
• Change feed: Change feed must be enabled on the source account. Azure storage monitors the $blobchangefeed to advise replication.
• Cross subscription and azure AD: Object replication is supported across subscriptions and azure AD tenants
• Replication Policy: A Storage account can be a source for up to two destination accounts. Each policy supports only a single pairing using a policy ID.
