Deployment Methodology for DR
BeyondTrust Password Safe can be deployed in many different configurations to scale from single site installations to multi-site, geographically dispersed environments. This document focuses on active/active deployment using U-Series Appliances.
In an active/active deployment, U-Series Appliances contain all components necessary to deploy the solution including SQL Server database, Scanner, BeyondInsight, and U-Series Appliance management components (backup/HA/U-Series Appliance administration etc).
Microsoft SQL Server 2014 Always On Availability Groups may consist of a primary replica, and up to 8 secondary replicas in either synchronous-commit or asynchronous-commit mode. Replicas are also supported in both Azure and AWS environments. A typical deployment model, comprising an asynchronous replica in the cloud, provides access to password data in the event that all on-prem components become unavailable.
SQL Server has a single master model, therefore only one replica has write access at any one time; however, replicas may be located in multiple locations for the event of database failover.
