Installation of Alfabet

The following installation procedures describe installation of Alfabet for new installations as wenn as upgrade from previous Alfabet releases.

Alfabet consists of the following components:

Server-side components: Server-side components can be installed on different hosts. The hosts must have the same server time. An Alfabet installation on server-side consists of:

• Database layer: One or a cluster of database servers. An instance is based on a single Alfabet database.
• Solution/Presentation layer: One or multiple web servers running an Alfabet Web Application and a single running Alfabet Server.

  A failover connection management is available for the Alfabet Server. Multiple Alfabet Server (services) can connect to the same database, but only the first connected Alfabet Server will be used to execute services, like for example sending of emails, on the database. All other Alfabet Servers will be remain inactive. If the active Alfabet Server service is either shut down or not available because of any issues, one of the other connected Alfabet Servers will take over and execution of any events handled via the Alfabet Server is consistently ensured.

  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.

Client-side components: Users can access Alfabet via a browser. Alfabet 11 supports Microsoft® Edge®, Google Chrome® 37.0 or higher, Mozilla® Firefox® 24.0 or higher, and Apple® Safari® 7.0 or higher.

Administrators and solution designers must install the Alfabet Administrator and the Alfabet Expand Windows Client on a host with access to the Alfabet database.
