Assume you are planning Web server computer capacity for a business that has 5000 business customers and sells about 1200 different products. Each customer buys between 10 and 50 items two or three times each month. The business has 300 employees, 200 of whom regularly interact with the companys online sales system.
As you learn more about disk storage options for the Web server, you learn that many companies selling Web servers offer a configuration option for controlling those computers disk drives called RAID. Using the Web and your library, investigate the purpose of RAID controllers. Learn what these controllers do and how they do it. Form an opinion regarding the suitability of these controllers in the Web server you are planning. Summarize your findings in a 300-word briefing report suitable for presentation to a nontechnical manager.

Question 2

Using your favorite search engine, find at least two companies that provide technical support for users of the Apache Web server software. Learn what services they provide and, if possible, what they charge. Review their Web sites to learn more about the companies and summarize your findings in a report of about 200 words.

Question 3

Identify the benefits and costs of using a decentralized instead of a centralized server architecture in an online business operation. Summarize your findings in about 100 words.

Answer to Question 1

Redundant Array of Independent Disks is a disk subsystem that increases performance or provides fault tolerance or both. RAID uses two or more regular hard drives and a RAID controller, which is plugged into motherboards that do not have RAID circuits. Today, most motherboards have built-in RAID but not necessarily every RAID configuration. In the past, RAID has also been accomplished by software only but was much slower.

Answer to Question 3

Each approach (centralized and decentralized) has benefits and drawbacks. The decentralized architecture spreads risk over a large number of servers. If one server becomes inoperable, the site can continue to operate without much degradation in capability. The smaller servers used in the decentralized architecture are less expensive than the large servers used in the centralized approach. That is, the total cost of 100 small servers is usually less than the cost of one large server with the same capacity as the 100 small servers.
