Amazon.com- A Technology Company

Although Amazon doesn't seem to twist with too many problems they dodgeatically test their system e really(prenominal) time they change an algorithm they do be in possession of oneness big one: scalability.

Scalability is defined as "The potential for a business or an aspect of a business to come about to function effectively as its size increases." (Money Words: Scalability). This is face a lot for a company like Amazon.com, where " huge" does not even begin to describe the scale of its systems, its guest base, or its product lines. Amazon.com has six global web billets (Kohavi and Round, 2004). Because Amazon is incessantly adding new technology to provide refinements to its web site experience, its oft-modified systems do occasionally hit a glitch. Jeff Bezos laughingly tells the story of the very first glitch, which occurred in 1995 when Amazon.com was still being run from his garage. He had hired an excellent computer guru who tested the web site and discovered that a customer could order a interdict quantity of books; not only that, when the customer placed that forbid order, his credit card was credited for the amount of the sale! (Amazon.col: Differentiating with Technolo

An interview with an unnamed Amazon.com IT tech revealed just about of the reasons behind the scalability problem. "For one thing," he stated, "the system is extremely complex and always being modified. "For an another(prenominal)wise, there is no way to bash how many transactions are going to hit the servers at any given time and overflow the buffers. We can exploit to guess at the maximum and allow plenty of room, further there are no guarantees." Bob Reeder, CIO of Alaskan Airlines, Inc., echoes this sentiment.

"You have a buffer of capability, but you know at near point you might exceed it," Reeder says. "We've tried to have an pointless capacity on our Web site. We use the heaviest day we've ever so had, propagation three. You hope that's enough." Upon hearing that Delta's site crashed under the physique of traffic that was triple its normal levels, Reeder pauses.

"Maybe three times isn't enoufh" (Kontzer, 2005).

A third option would be to make the system entirely modular. Modularity makes it easier to find and change code without affecting other code in the system, and it is much easier to distribute among a procedure of programmers without causing errors. Modules can easily be added or remote with only minimal changes to a restricted number of other staffs in most cases just the main driver, in fact. Furthermore, it is easier to cargo hold up with the documentation modifications that must accompany these changes if the documentation is as well modular. Add one module of code, add one module of documentation. A modular system is infinitely more ascendible than a non-modular system and there is an added advantage of always wise to(p) where you are.
