Introduction

PrizmDoc Application Services (PAS) is designed to scale out well. By default, it will run multiple threads on a single machine whenever it is capable, and it can be installed to run on multiple machines easily. You will need to do the following in order to run PAS on multiple servers:

• Install the PAS component on all machines that you would like to use.
• On each machine, configure all filesystem-based storage in the PAS configuration file to point to a shared location. It is recommended that you use a shared Network Attached Storage (NAS) device that is accessible to all PAS instances.
• On each machine, find the correct PAS configuration file, and adjust the settings so that each instance of PAS is pointing to the same PrizmDoc Server or PrizmDoc Cloud entry point.

You can find out more about configuring PrizmDoc Server with a cloud entry point for a cluster environment in the PrizmDoc Viewer Cluster Mode topic.

Make sure to re-start PAS after every configuration change, in order for the changes to take effect.

Load Balancing

There is no special consideration for load balancing several PAS servers. Any request can be routed to any instance of PAS, and you can use any off-the-shelf load balancer to handle the routing.
