This chapter concentrated on the options available to you on the Central Administration Home page, such as configuring administrative tasks and defining the services and roles that are provided by the servers in the farm topology. You also looked at the Operations interface in Central Administration and saw how most of the configuration options in this page were farmwide and had a global impact on all servers configured in the farm. This chapter did not cover all the sections on the page because other chapters in this book go into those topics in detail.
Finally, you looked at adding more Web servers to an SharePoint Server 2007 farm, expanding out to a medium farm, and configuring the services and roles that each server provides in that topology. To add resilience to the Web servers, you added Network Load Balancing. By doing this, requests from your users were spread between the two Web servers. You also saw how you needed to configure both the host header and DNS properties to make the name resolution work correctly by pointing to the load-balanced cluster's fully qualified domain name.
In the next chapter, you will look at the final part of Central Administration, which is the Application Management interface.
