Case Study 2 Part 1 A local real estate agency has asked you for help in setting up a presence on the Internet. The agency has started to create a budget and needs to determine how much the server hardware will cost. Its plan is to start with a fairly small Web site, but in the near future the agency wants to have listings of all local homes for sale, including pictures and virtual tours. The agency averages about 1,000 listings at a time. Unfortunately, the agency cant give you many details on how many simultaneous users the site will have; the sites reliability is the most important consideration at the moment. Because the agency hasnt yet decided on which operating system and applications to use, youll need to provide some choices. Put together a proposal listing two hardware configurationsone that would run a Windows system and one that would run a Red Hat Linux system. The agency is on a tight budget so it wants as cheap a solution as possible but with on-site support. Part 2 The real estate agency is happy with your proposal, but needs some time to make a decision. In the meantime, your boss has suggested that you pre- pare for any decision that the agency makes. This means that you need to develop some documentation. Prepare a diagram that shows the real estate agencys network. It has six machines in the office and a router with a fractional T1 connection to the Internet. Assume that the routers IP address is 24.16.5.200 and that the port on the Internet side of the firewall is 24.16.5.201. For the computers on the private side of the network, you get to choose the addresses; base them on the class C private address 192.168.0.0. Part 3 The real estate agency has also been selected to support regional home listings. As a result, its new Web site will require a Web server environment that is not only many times larger, but also able to grow rapidly without requiring a new, bigger server. How would you build this environment?
