Case Question - Contoso Ltd.
Contoso Ltd. provides commercial and non-commercial real estate buying, selling services to a densely populated region. It has more that 100,000 listing and employs approximately 3,000 agents in 120 offices.
The company’s Web site provides free and unrestricted access to a complete listing of all real estate properties except properties listed within the previous 24 hours. Those who pay a membership fee gain access to the most current listings. Brokers in the branch offices are responsible for adding new listings, but they often delay adding the new listings.
The company’s marketing department recently entered into a contract with another company to add mode details to the listing information and to expedite entry of the records. A new multimedia service is being introduced. It includes narration and allows users to navigate panoramic view of selected properties.
An Advertisement of the new features significantly increased the popularity of the Web site. The number of page views per day increased from 10,000 to 100,000. This activity is anticipated to continue to increase as more listings are enhanced.
Recently, an update to a mortgage calculator program on the Web server created a conflict with the database hosting the user table. The anonymous access to the Web site was unaffected. However, paid members could not access new listings. The failed service was not discovered for three days, causing embarrassment to the company.
Existing Environment
The company’s Internet Web site is hosted at an Internet Presence Provider (IPP) that has redundant 100-Mbps connections to the Internet. The Web site is located on a single network subnet and is contained on a two-node Cluster service cluster. Each server is running Microsoft Windows NT 4.0 Enterprise Edition and has four processors. The cluster is in active/passive configuration and has fiber connectivity to RAID 5 storage. Each server is a domain controller and runs Microsoft Internet Information Server 4.0 Microsoft SQL Server 6.5 is used for the membership database.
The company’s headquarters is connected to the Internet by a T1 line. A staging server at headquarters is used to update content to the production Web site. Membership updates are made directly on the Web site’s production server. Direct 56-kbps frame-relay lines connect all branch offices. The connections have a committed information rate of 32 Kbps.
Tax and title information is hosted on the company’s mainframe computer and is updated daily from external sources.
Business Requirements
The company has established an aggressive schedule to enhance the Web site’s content and to add features. The following features must be added:
Web site
• Using a method similar to a that of shopping cart, members must be able to accumulate portfolios for properties and use online tools to explorer and analyze the properties.
• Popular listings will include multimedia files. After users specify a connection speed, all subsequent content during that sessions will be delivered at the specified bandwidth.
• Information that highlights regional attractions and services must be available to all users.
• Tax and title information must be available to members.
Content management
• New listings must be processed on the same day they are received.
• Content and configuration update procedures must be established, and extensive monitoring must be enforced.
• The Web site must include methods for secure payments.
• Office employees and the mobile sales force must have secure Internet access to information.
• Security, availability, and membership privacy must have the highest priority.
• Buyers of homes must have secure access to their loan and purchase documents.
Technical Requirements
The company has established the following technical requirements:
Web sites
• All servers must run Windows 2000.
• No single point of failure will be tolerated. However, short delays due to cluster transitions are acceptable.
• Membership records need to maintain a change history. The membership database must be updated in real time. Changes to customer portfolios need to be maintained even if a Web server fails.
• All external confidential communication must be encrypted.
• Employee services must be hosted on intranet Web servers.
• Buyer, tax, and title documents will be stored on the mainframe computer. The connection between the mainframe computer and the Web site must be redundant. All communications must be encrypted. The services supporting the connection must have certificate-based authentication and support immediate changes to the network.
• The headquarters must have redundant connections to the Internet.
• The only publicly available IP address will be the firewall.
• Microsoft Application Center 2000 will be used for health monitoring.
• The multimedia feature will use non-streaming Macromedia Shockwave files. The average size of each file is 2 MB. Currently only 5 percent of the listings have this feature.
• The design needs to accommodate the fact that 50 percent of the listings will use the multimedia feature. Fault tolerance is required.
• Components that support the multimedia and regional attractions features will perform read-only operations on the multimedia files.
Lab testing
• A lab was set up and preliminary testing indicated that more that eight NLB servers running at capacity will saturate a 100-Mbps Ethernet segment. NLB must not contain more that eight servers.
• Load testing of 5,000 users indicated that each connection will use an average of 1 Kbps, not including multimedia down loads.
