PreviewServer

Within the Enterprise Content Management (ECM) environment, good scalability of the platform for central management and maintenance of the content is an essential criterion for sustainable operation of a CMS. CMS's steadily growing field of use makes it indispensable for it to grow too. For this reason, FirstSpirit™ provides the opportunity for operations involving intensive calculations to be performed within the cluster.

Architecture of the Preview cluster

For seamless scaling in large, growing CM structures, FirstSpirit™ enables services involving intensive calculations, such as generation, preview generation, WYSIWYG WebClients (WebEdit) and even WebMonitor to be swapped out to so-called cluster nodes. These nodes relieve the central FirstSpirit™ master server of operations involving intensive calculations and are coordinated by it. This powerful architecture provides consistent content management with the option of performing parallel generation of extensive databases from several projects without slumps in performance for the editors.

Within the preview cluster, the WYSIWYG WebClients and the preview calculation are assigned to the individual preview servers via an upstream load balancer. The editors can therefore be distributed over several preview servers and the FirstSpirit™ master server is relieved of the preview calculation and execution of the WebClients.

This load distribution approach in the FirstSpirit™ cluster can be excellently combined with the generation server. In this case, the FirstSpirit™ master server only coordinates the repository and the linked cluster nodes.

Cluster administration

Cluster mode is conveniently configured under Windows using the client for server and project configuration of the master server. In Linux/Unix it suffices to adjust a few configuration files. In each case, the status of the configured preview server can be viewed in the server and project configuration client (cf. screenshot).
