2 Introduction

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.

2.1 Document 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.

2.2 Intended Audience

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

2.3 Adobe Connect Deployment Architecture

3 Template

Kemp has developed a template containing our recommended settings for this workload. You can install this template to help create Virtual Services (VSs) because it automatically populates the settings. You can use the template to easily create the required VSs with the recommended settings. You can remove templates after use and this will not affect deployed services. If needed, you can make changes to any of the VS settings after using the template.

Download released templates from the following page: LoadMaster Templates.

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

4 Enable 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 routes traffic so that the Real Server sees 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 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 Web User Interface (WUI), go to System Configuration > Miscellaneous Options > Network Options.

2. Select the Subnet Originating Requests check box.

5 Configure Adobe Connect Virtual Services

The following sections show how to manually configure Virtual Services for Adobe Connect.

5.1 Adobe Connect HTTPS Offloaded

The following are the steps involved and the recommended settings to configure Adobe Connect HTTPS Offloaded Virtual Service:

1. In the main menu of the LoadMaster Web User Interface (WUI), go to Virtual Services > Add New.

2. Enter a valid IP address in the Virtual Address text box.

3. Enter 443 in the Port text box.

4. Enter a recognizable Service Name, for example Adobe Connect HTTPS Offloaded.

5. Ensure tcp is selected as the Protocol.

6. Click Add this Virtual Service.

7. Configure the settings as recommended in the following table:

Section	Option	Value	Comment
Standard Options	Transparency	Disabled
	Persistence Mode	None
	Scheduling Method	round robin
SSL Properties	SSL Acceleration	Enabled
	Cipher Set	Best Practices
Advanced Properties	Add a Port 80 Redirector VS	https://%h%s	Click Add HTTP Redirector.
Real Servers	Real Server Check Parameters	HTTP Protocol
	Checked Port	8443	Click Set Check Port.
	URL	/servlet/testbuilder	Click Set URL.
	HTTP Method	GET
	Use HTTP/1.1	Selected

8. Add the Real Servers:

a) Click the Add New button.

b) Enter the IP address of the Adobe Connect server.

c) Enter 8443 as the Port.

The Forwarding method and Weight values are set by default. An administrator can change these.

d) Click Add this Real Server. Click OK to the pop-up message.

e) Repeat steps b) to d) above to add more Real Servers as needed, based on the environment.

5.2 Adobe Connect RTMP

The following are the steps involved and the recommended settings to configure Adobe Connect RTMP Virtual Service:

1. In the main menu of the LoadMaster Web User Interface (WUI), go to Virtual Services > Add New.

2. Enter a valid IP address in the Virtual Address text box.

3. Enter 1935 in the Port text box.

4. Enter a recognizable Service Name, for example Adobe Connect RTMP.

5. Ensure tcp is selected as the Protocol.

6. Click Add this Virtual Service.

7. Configure the settings as recommended in the following table:

Section	Option	Value	Comment
Basic Properties	Service Type	HTTP/HTTPS
Standard Options	Force L4	Enabled
	Persistence Mode	None
	Scheduling Method	round robin
Real Servers	Real Server Check Parameters	TCP Connection Only
	Checked Port	1935	Click Set Check Port.

8. Add the Real Servers:

9. Click the Add New button.

a) Enter the IP address of the Adobe Connect server.

10. Enter 1935 as the Port.

The Forwarding method and Weight values are set by default. An administrator can change these.

b) Click Add this Real Server. Click OK to the pop-up message.

c) Repeat steps b) to d) above to add more Real Servers as needed, based on the environment.
