After completing this lab, you’ll be able to
In this lab you’ll design a network topology that supports distributed applications. The applications will rely on ASP and COM+ components to access data from a SQL Server database. In addition, you’ll further refine your design to provide Web-based e-mail services to your Internet users. Each exercise in this lab addresses one facet of the topology design. You’ll first implement a simple Web site that supports static content. Next, you’ll add database support so you can support dynamic content on your site. Finally, you’ll add Web-based e-mail services to allow company employees to check e-mail when out in the field.
Before you begin this lab, you must be able to
Lucerne Publishing has operations throughout the world. The company has decided to implement a Web site that supports static content that will be used to provide general information about the company and its products. Lucerne Publishing also wants to provide specific information about the books it publishes. Because this information changes regularly, content for the site should be generated dynamically so it’s easy to maintain the site and customers can easily search for specific titles. The information should be available to anyone who’s interested. In addition to the customer-related services that the company wants to provide, Lucerne Publishing also wants employees working in the field to be able to access their e-mail accounts on a regular basis, regardless of where they’re traveling. As the network administrator for the company, you must design a network topology that fulfills these requirements.
Lucerne Publishing is anxious to get its Web site online as quickly as possible. Initially, the company would like you to implement the Web servers so general company information can be posted as soon as possible. You plan to use Application Center 2000 to create an NLB cluster that contains three servers. You also plan to implement two Active Directory service computers within the perimeter network to support various systems as they’re added to the network. Your design will include redundant component and paths to ensure high availability. In addition, you want the site to support the use of distributed applications as they’re implemented into your network. COM+ components will be stored on the Web cluster.
As you prepare your network design, you also want to take into consideration how the initial content will be deployed. The content consists only of static HTML pages and their supporting graphics. After the content has been developed, you’ll move it to a test environment. From there, it’ll be staged to the production environment.
You’ve implemented the initial network design and deployed the content to the Web servers. You’re now ready to set up the environment so that you can provide dynamic content to your users. Your development team has developed ASP applications that use COM+ components to access data from a SQL Server database. The applications have been tested and are ready to be staged. You plan to implement a SQL Server cluster that contains two servers. You’ll use a single-instance configuration so that one server is active and the other is passive.
Once you’ve integrated SQL Server into your design and deployed the COM+ applications, you’re ready to integrate Exchange into your site. You plan to use a multiserver configuration for Exchange and use Windows Clustering technologies to support high availability.
