To achieve database HA we recommend deploying AWS RDS Microsoft SQL Server into at least 2 Availability Zones.
After deploying RDS you will need to do the following actions:
• Change the registry key ‘Portal’ to point to the RDS database cluster endpoint
• Edit the Web.Config in D:\Portal on the appliance from “127.0.0.1” to the RDS Cluster endpoint
• Stop the ‘PortalService’ service on the appliance. Edit the service config file in “C:\Program Files (x86)\Nuvens Consulting Ltd\Nuvens AWS WorkSpaces Management Portal Service\PortalService.exe.config” and change the database connection string from “127.0.0.1” to the RDS Cluster endpoint. Then restart the appliance
