Foreword

Most software developers who work on the Internet love change. Change presents

a new challenge, a new paradigm, and new technologies to learn. To realize this,

all you have to do is look at the evolution of computers. During the 70s, we worked

in a world of mainframes and raised loors. Only special people got to touch the

computer, while others had to be content watching from outside of the ishbowl.

The 80s brought the mini-computer with dedicated CRT terminals. You could show

data on the screen in any color as long as it was green, but the computer was down

the hall in the back room. The 80s also introduced the personal computer. As PC

power grew, the mini was replaced with the LAN-connected PC.

The 90s saw the advent of the Internet, and people dialed in, and in the early 2000s,

the Internet went viral. As high-speed connections became common, the Internet

replaced corporate networks. Computers went from rooms to luggables to "in my

briefcase" to "in my pocket."

In 2010, we are seeing the growth of cloud computing. Selecting a brand and model

of server computer is being replaced with renting a virtual server at a hosting service

like Amazon. The purchaser of these virtual servers doesn't have to select a hardware

"brand." I no more care about the brand of computer than I would care about what

brand of pipe the water utility used to connect to my house. All I am buying is cycles

and reliability.

This move to virtual servers also changes the capital required to propose the

next viral application. I don't need to buy a large database cluster, hoping for the

acceptance to ill it. I am billed for usage, not capacity. SimpleDB is one of those

virtual offerings and the topic of this book.
