- 2. 1.Introduction to How Amazon Works Amazon.com sells lots and lots of stuff. The direct Amazon-to-buyer sales approach is really no different from what happens at most other large, online retailers except for its range of products. You can find beauty supplies, clothing, jewelry, gourmet food, sporting goods, pet supplies, books, CDs, DVDs, computers, furniture, toys, garden supplies, bedding and almost anything else you might want to buy. What makes Amazon a giant is in the details. Besides its tremendous product range, Amazon makes every possible attempt to customize the buyer experience.
- 3. 2.Amazon Technology Amazon employs the Netscape Secure Commerce Server using the SSL (secure socket layer) protocol (see How Encryption Works to learn about SSL). It stores all credit card numbers in a separate database that's not Internet-accessible, cutting off that possible entry point for hackers. Customers who are particularly cautious can choose to enter only a partial credit card number over the Internet and then provide the rest by phone once the online order is submitted. Aside from the usual security concerns regarding online credit-card purchases, Amazon suffers from the same phishing problem that has plagued eBay and PayPal, so watch out for fake e-mails asking for your Amazon.com account information.

- 4. The data warehouse is roughly divided into three functions: query, historical data and ETL (extract, transform, and load -- a primary database function that pulls data from one source and integrates it into another). The query servers (24.7 TB capacity) contain 15 TB of raw data in 2005; the click history servers (18.5 TB capacity) hold 14 TB of raw data; and the ETL cluster (7.8 TB capacity) contains 5 TB of raw data. Amazon's technology architecture handles millions of back-end operations every day as well as queries from more than half a million third-party sellers. According to a report released by Oracle after it helped migrate Amazon's data warehouse to Linux in 2003 and 2004, the central task process looks something like this:
- 5. 3.Amazon E-commerce Amazon.com has always sold goods out of its own warehouses. It started as a bookseller, pure and simple, and over the last decade has branched out into additional product areas and the third-party sales that now represent a good chunk of its revenue (some estimates put it at 25 percent). Both retailers and individual sellers utilize the Amazon.com platform to sell goods. Large retailers like Nordstrom, Land's End and Target use Amazon.com to sell their products in addition to selling them through their own Web sites. The sales go through Amazon.com and end up at Nordstrom.com, Land's End.com or Target.com for processing and order fulfillment. Amazon essentially leases space to these retailers, who use Amazon.com as a supplemental outlet for their online sales.
- 6. 4.Amazon Tools, Marketing and Community The goal is pretty straightforward: "To be Earth's most customer-centric company where people can find and discover anything they want to buy online." The implementation is complex, massive and dynamic. Amazon's marketing structure is a lesson in cost-efficiency and brilliant self-promotion. Amazon's associates link to Amazon products in order to add value to their own Web sites, sending people to Amazon to make their purchases. It costs Amazon practically nothing. Some associates create mini-Amazons -- satellite sites that do new things with Amazon data and send people to the mothership when they're ready to buy. Amazon Light, built and maintained by software developer Alan Taylor, is one of those satellite sites.
