 # Enable Azure Active Directory authentication for Azure-SSIS Integration Runtime
 
-This article shows you how to enable Azure Active Directory (Azure AD) authentication with the managed identity for your Azure Data Factory (ADF) and use it instead of SQL authentication to create an Azure-SSIS Integration Runtime (IR) that will in turn provision SSIS catalog database (SSISDB) in Azure SQL Database server/Managed Instance on your behalf.

 ### High availability and disaster recovery
 
-High availability (HA) and disaster recovery (DR) can sometimes be combined together, although each has a slightly different strategy, especially when it comes to data. Data Lake Storage Gen2 already handles 3x replication under the hood to guard against localized hardware failures. Additionally, other replication options, such as ZRS improve HA while GRS & RA-GRS improve DR. When building a plan for HA, in the event of a service interruption the workload needs access to the latest data as quickly as possible by switching over to a separately replicated instance locally or in a new region.
+High availability (HA) and disaster recovery (DR) can sometimes be combined together, although each has a slightly different strategy, especially when it comes to data. Data Lake Storage Gen2 already handles 3x replication under the hood to guard against localized hardware failures. Additionally, other replication options, such as ZRS or GZRS (preview), improve HA, while GRS & RA-GRS improve DR. When building a plan for HA, in the event of a service interruption the workload needs access to the latest data as quickly as possible by switching over to a separately replicated instance locally or in a new region.
 
 In a DR strategy, to prepare for the unlikely event of a catastrophic failure of a region, it is also important to have data replicated to a different region using GRS or RA-GRS replication. You must also consider your requirements for edge cases such as data corruption where you may want to create periodic snapshots to fall back to. Depending on the importance and size of the data, consider rolling delta snapshots of 1-, 6-, and 24-hour periods, according to risk tolerances.
