Introduction

The CoreOne Suite can be installed and used as an “Multi-Line”-System. The CoreOne Suite-Components (“Web Service” and “Authentication Service”) are then installed on the same Server. And the “Application Services” are installed on a seperate server.
Also the databases are on entirely different servers.

Windows Server Construct with Database as a Galera Cluster:

Servers

For the Multi-Line-Installation, seven Servers are needed. Two Front- and two Backend-Server. The database will be separated and put on different servers. Since we use Galera Cluster in a Multi-Line, we would need atleast three Servers for MariaDBs.

The Backend-Server needs to cover the requirements according to System requirements CoreOne Application Services release 8.x and above.

The Frontend-Server needs to cover the requirements according to System requirements CoreOne Web Services release 8.x and above.

The Database-Server needs to cover the requirements according to https://itsense.atlassian.net/wiki/spaces/IKB/pages/2187329561.
