Zone Redundant Storage (ZRS) - Stores 3 copies of your storage in multiple datacenters, but in the same region. Geo Redundant Storage (GRS) - Stores 3 copies of your storage in primary region, and other three copies stored in secondary region. Read Access Geo Redundant Storage (RA-GRS) - Stores 3 copies of your storage in primary region, and other three copies stored in secondary region.

  30. 30. • Consider Hot/Cool/Cold • Consider defining your data by how quickly you need it • In Azure’s case, there are dramatic savings if you store for longer than 180 days and dont need that data for up to 15 hours • What level of redundancy is needed? • Can some data be easily reconstructed if lost • On Azure, evaluate the type of storage account needed • If you use high volumes of transactions or geo-replication bandwidth, don’t use GP v2. • Evaluate if have enough storage to benefits from the lower costs of GB storage.
