Install Microsoft SQL Server 2017 or 2019
Microsoft SQL Server 2017 and 2019 allow you to install the database engine and SQL Server Reporting Services (SSRS) on separate hosts. Parallels RAS 17.1 (and newer) supports this deployment scenario and gives you the ability to use SQL Server Reporting Services and the SQL Server database engine installed on separate hosts.
For step-by-step instructions on how to install and configure Parallels RAS Reporting Service with SQL Server 2019 and Microsoft SSRS 2019, please read the following Parallels KB articles:
