Install VertiGIS Studio Printing in a Load-Balanced Environment

A typical VertiGIS Studio Printing deployment consists of one server that hosts both the Printing software and its data directory. This deployment case is suitable for most installations and can be installed and updated out of the box.

Alternatively, you may prefer to install VertiGIS Studio Printing in a multi-server environment.

In a multi-server VertiGIS Studio Printing deployment, each server operates independently to generate print content. This means that users can still generate prints if one server fails, and that servers do not share job information with each other.

All servers share a single copy of the Printing data directory. For VertiGIS Studio Printing, you need to set up a redundant file share for the data directory. This provides redundancy for Printing's configuration files and any temporary files.

Prerequisites

To run VertiGIS Studio Printing in a load-balanced environment, ensure the following requirements are met:

• You have a load balancer.

• Your load balancer does not rewrite URL paths.

• You have enabled sticky sessions on the load balancer.

  Sticky sessions (also known as 'session affinity' or 'session persistence') must be enabled on the load balancer. When sticky sessions are enabled, all requests from a client are routed to the same server for the duration of that client's session.

Installation Steps

The main installation steps for a load balanced deployment of VertiGIS Studio Printing are the same as for a typical on premises deployment, with some exceptions and additional steps—described on this page.

The installation steps are as follows:

1. Set up file share. See Set Up File Share, below.

2. Install VertiGIS Studio Printing:

   1. On the on-premises installation deployment page, see Install VertiGIS Studio Printing on Premises.

   2. On each server, follow all steps as for a typical on-premises installation.

3. Configure post-installation settings:

   1. On the on-premises installation deployment page, see Configure Post-Installation Settings.

   2. On each server, follow all steps as for a typical on-premises installation, with the exception of the Data and Portal sections.

   3. Complete Data configuration: See Data, below.

   4. Complete Portal configuration: See Portal, below.

4. Configure load balancer. See Configure load balancer, below.

Set Up File Share

Set up a redundant file share for the data directory. The file share will be shared between all servers, providing redundancy for Printing's configuration files and any temporary files.

To set up the file share:

1. Find your existing file share, or create a new one.

   We recommend that you choose a permanent location for the data directory file share now. If you change the data directory location later, you will lose access to your existing print templates.

2. Within the file share, create a folder for the VertiGIS Studio Printing data.

3. Assign the VertiGISStudioPrinting application pool user Read / Write permissions. Typically this is the DomainName\MachineName$ user.

Configure Post-Installation Settings

Data

The Data panel allows you to select a location for VertiGIS Studio Printing to store print templates and other Printing-related files.

• Click Browse and select the file share folder location.

Portal

The Portal panel allows you to register your Portal for ArcGIS or ArcGIS Online application.

Follow the instructions provided for a Portal, with the exception of the Redirect URL.

• Set the Redirect URL to use the public address of your load balancer.

Configure Load Balancer

• Configure your load balancer to direct traffic to the servers on which VertiGIS Studio Printing is installed.

  Sticky sessions (also known as 'session affinity' or 'session persistence') must be enabled on the load balancer. When sticky sessions are enabled, all requests from a client are routed to the same server for the duration of that client's session.
