System Overview
Figure:
An Alfabet installation on server side consists of two layers:
- Database layer: One or a cluster of database servers. An instance is based on a single Alfabet database.
- Solution/Presentation layer: 1 or multiple Web Servers running an Alfabet Web Application and a single running Alfabet Server.
For use of the Alfabet RESTful services one or multiple separate web applications Alfabet API Server running on the same or different Web Servers as the Alfabet Web Application.
If the server side components are installed on different host, all hosts must have the same server time.
Users can access Alfabet via a browser. In the following, the access via the browser is called Alfabet Web Client.
