Today, Google spends hundreds of millions of dollars on space, power, and bandwidth for its hundreds of thousands of servers hosted in its own data centers. But Google's infrastructure wasn't always so vast.

In 1998, Google was powered by around 50 servers that fit in a space smaller than a typical American teenager's bedroom. Urs Hölzle, one of the company's first engineers, has posted a copy of one of the company's first bills from the data center that held Google's servers:

"A megabit cost $1200/month and we had to buy two," Hölzle writes. Today, of course, a 2 megabit connection is considered painfully slow, and costs a tiny fraction of $2400 per month.
