Multiple Backends
Based on NGA Standard or NGA Premium more connections from a backend to a database are possible and can be extended. Redundancy is included for InfluxDB®. The redundancy means WinCC OA redundancy and the InfluxDB® redundancy as described in the chapter Redundant Scenario.
In the example shown below two backends are used. Therefore, the NGA Standard package or NGA Premium package is required.

Two backends are running in-proc with the frontend manager on a local machine. One database is running locally, another remote.
