Personal Desktops, Hosted Shared Desktops, and Remote PC Desktop (for Automatic enrollment) would be available during a SQL Server outage. Personal Desktops operate independently of SQL Server, Hosted Shared Desktops can often continue functioning as they do not rely on SQL Server for operational continuity, and Remote PC Desktop can be configured to work without SQL Server connections. However, Hosted Windows and Browser Applications and Citrix Studio typically depend more directly on SQL Server access and may not be available during an outage.
