Using Internet Services clustering to plan your system
Clustering refers to running multiple services of the same type, for example Internet Services or Voice Services, from a single FirstClass server. You can use clustering to route different Internet protocols (for example, SMTP, NNTP, or HTTP) to better organize your FirstClass environment. For example, you can dedicate a clustered machine to only handle one protocol or you can have multiple clusters for the same protocol to balance the traffic. You can also run multiple clusters on separate machines gatewayed to one FirstClass server on Mac OS X and Windows platforms.
For details on clustering Voice Services, see Clustering Voice Services.
In all cases, you must have Internet Services already installed on your clustered machines and the client installed to configure your gateway login settings file and for testing purposes.
Although each clustered service is set up and configured independently, it is possible to share components such as web content or filters using FirstClass folder linking.
Note
If you want to create web sites for your clusters, see Creating a FirstClass web site.
In this chapter, we discuss:
Although the examples we cover in this chapter may cover many of the scenarios you may want to implement on your system, they are by no means exhaustive. Once you understand Internet Services clustering you can configure multiple combinations (either simple or complex) for your FirstClass site. For clarity, we highly recommend you diagram out your clustered environment before you create it.
