Introduction to How Amazon Works

In 1995, Amazon.com sold its first book, which shipped from Jeff
Bezos' garage in Seattle. In 2006, Amazon.com sells a lot more than
books and has sites serving seven countries, with 21 fulfillment
centers around the globe totaling more than 9 million square feet of
warehouse space.
The story is an e-commerce dream, and Jeff Bezos was Time
magazine's Person of the Year in 1999. The innovation and business
savvy that sustains Amazon.com is legendary and, at times,
controversial: The company owns dozens of patents on e-commerce
processes that some argue should remain in the public domain. In
this article, we'll find out what Amazon does, what makes it different
from other e-commerce Web sites and how its technology
infrastructure supports its multi-pronged approach to online sales.
Amazon Technology

The massive technology core that keeps Amazon running is entirely Linux-
based. As of 2005, Amazon has the world's three largest Linux databases,
with a total capacity of 7.8 terabytes (TB), 18.5 TB and 24.7 TB respectively
[ref]. The central Amazon data warehouse is made up of 28 Hewlett Packard
servers, with four CPUs per node, running Oracle 9i database software.
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
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.
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.
Amazon Tools, Marketing and Community

A recent development in customer tracking actually collects information on
people who may have never visited Amazon.com. Amazon's gift-giving
recommendations collect data on the stuff you buy for other people. For
instance, if you buy a toy train set in December and ship it to your nephew,
Amazon knows you give gifts to a boy aged four to 10 who lives in Ohio and
likes trains. Might your nephew enjoy the latest addition to that train series?
Might he also have an interest in RC cars? Amazon will give you all sorts of
ideas about what to get your nephew when the next holiday season rolls
around.
This type of information gathering has generated a fair amount of
controversy. Some say Amazon gathers too much information for comfort,
and the Electronic Privacy Information Center reports that in 2000, Amazon
started sharing its customer data with its partners and subsidiaries. The
concern has increased with the tracking of "gift-giving habits," because the
gift-giving information Amazon collects could be about minors, which is
against the law, and because the gift receivers don't even know that their
name, age, gender, location and interests may be stored in Amazon's
database of customer information.
