Appendix A: Clustering Breeze Presentation Platforms

If your Macromedia Breeze license permits, you can install the Breeze Presentation platform on two or

more computers, and then cluster the Breeze Presentation platforms to provide load balancing and

failover.

Clustering Breeze Presentation platforms has the following advantages:

• You can effectively use third-party hardware or software to provide load balancing and failover for

HTTP requests. Clustering Breeze Presentation platforms allows them to share session data with

each other so that load balancing and failover through third-party solutions can be effective.

• Clustered Breeze Presentation platforms provide their own load balancing for requests to create

Breeze Flash presentations from Microsoft PowerPoint presentations.

• All Breeze Presentation platforms in a cluster have copies of the same content. If one computer in a

cluster fails, the Breeze Presentation platform on another computer in the cluster can take over and

supply the same content.

Note: If you are using the Breeze Live stand-alone configuration, all references to the Breeze Presentation platform in

this appendix apply also to the Breeze application server.

This appendix explains how to cluster Breeze Presentation platforms and verify that the cluster functions

successfully. The following topics are discussed:

• “Setting up a cluster of Breeze Presentation platforms” on page 26

• “Verifying failover for HTTP requests” on page 27

• “Verifying replication of content across the cluster” on page 27

Setting up a cluster of Breeze Presentation platforms

Each Breeze Presentation platform in a cluster must be able to access the Breeze database. Because

licensing restrictions do not allow more than one Breeze Presentation platform to access the Breeze

database engine, you must use Microsoft SQL Server 2000 for the Breeze database.

The following figure illustrates a cluster with a load balancer and with the Breeze Presentation platform on

three computers.
