Adobe Connect

 

1Introduction

Adobe Connect is a web conferencing solution which enables corporations and government agencies to improve collaboration, webinars and eLearning through interactions. It integrates several tools into an online meeting room including:

  • Video conferencing
  • Chat
  • Whiteboards
  • Desktop sharing
  • File sharing

Adobe Connect offers flexibility to presenters and participants. Numerous tools can be used in any combination to facilitate meetings. Adobe Connect is accessible on desktops, tablets and mobile devices with the Adobe Connect Mobile application installed.

Such a powerful tool requires reliable and powerful support. The KEMP LoadMaster delivers an exceptional, cost-effective and easy to use solution which, by employing Adaptive Load Balancing, balances requests across Adobe Connect.

When deployed as a pair, two LoadMasters give the security of High Availability (HA). HA allows two physical or virtual machines to become one logical device. Only one of these units is ever handling traffic at any particular moment. One unit is active and the other is a hot standby (passive). This provides redundancy and resiliency, meaning if one LoadMaster goes down for any reason, the hot standby can become active, therefore avoiding any downtime. For more information on HA please refer to the: High Availability (HA), Feature Description.

1.1Document Purpose

This document provides guidance on deploying Adobe Connect with a KEMP LoadMaster. The KEMP Support Team is available to provide solutions for scenarios not explicitly defined.

The KEMP support site can be found at: https://support.kemptechnologies.com.

1.2Intended Audience

This document is for anyone deploying Adobe Connect with a KEMP LoadMaster.

2Adobe Connect Template

KEMP has developed a template containing our recommended settings for Adobe Connect. This template can be installed on the LoadMaster and used when creating Virtual Services. Using a template automatically populates the settings in the Virtual Services. This is quicker and easier than manually configuring each Virtual Service. If needed, changes can be made to any of the Virtual Service settings after using the template.

Download released templates from the Templates section on the KEMP documentation page: http://kemptechnologies.com/documentation/.

For more information and steps on how to import and use templates, refer to the Virtual Services and Templates, Feature Description

3Enable Subnet Originating Requests Globally

It is best practice to enable the Subnet Originating Requests option globally.

In a one-armed setup (where the Virtual Service and Real Servers are on the same network/subnet) Subnet Originating Requests is usually not needed. However, enabling Subnet Originating Requests should not affect the routing in a one-armed setup.

In a two-armed setup where the Virtual Service is on network/subnet A, for example, and the Real Servers are on network B - Subnet Originating Requests should be enabled on LoadMasters with firmware version 7.1-16 and above.

When Subnet Originating Requests is enabled, the LoadMaster will route traffic so that the Real Server will see traffic arriving from the LoadMaster interface that is in that network/subnet.

When Subnet Originating Requests is enabled globally, it is automatically enabled on all Virtual Services. If the Subnet Originating Requests option is disabled globally, you can choose whether or not to enable Subnet Originating Requests on a per-Virtual Service basis.

To enable Subnet Originating Requests globally, follow the steps below:

  1. In the main menu of the LoadMaster WUI, go to System Configuration > Miscellaneous Options > Network Options.

  1. Tick the Subnet Originating Requests check box.
