The Web Server 7.0 is a secure and highly available server that you can use to host web sites. When you install the Web Server 7.0 product, the following two server instances are installed:
Administration Server
Web Server instance
The Administration Server is a web-based server that contains the Java forms that you use to configure all of your Web Server instances. After you install the initial Web Server instance, you can use the Administration Server to install additional instances.
The Sun Java System Web Server 7.0 Plug-In 1.0 enables you to use the N1 Service Provisioning System to install and control Web Server 7.0 Administration Servers and Web Server instances. Using the provisioning system, you install an Administration Server and the first Web Server instance together. The provisioning system cannot install additional instances of the Web Server.
