The 25 most powerful people in networking

Send to colleague

Michael Wilson, chief scientist,
eBay

M. WilsonEBay has truly gone where none have tread before, almost single-handedly creating consumer-to-consumer e-commerce, in large thanks to the creator of its architecture, Michael Wilson.

EBay's success has spawned innumerable copycats, and indeed, an entire industry. The mighty consumer sites of Yahoo and Amazon.com stumbled over themselves to add auction capabilities. Entire business-to-business auction sites also have been built. Thus, last year, eBay moved from phenomenon to establishment.

With that, Wilson's prestige has grown from notable to powerful. Not that he hasn't taken his hits this year. Like other trading networks, an auction system must have extremely high reliability. Because eBay sits on the leading edge for consumer-to-consumer trading, its reliability weighs heavily in the public eye. Last July, when it suffered a multiday crash, the industry coined a new term, an "eBay black-eye" - a big outage that costs big bucks.

And yet for millions, Wilson's architecture holds fast. In fact, eBay has more than 5.6 million registered users, lists almost three million items and adds more than 300,000 auctions per day. It conducts more than $1 billion of gross merchandise sales annually. And it conducts all of this business under the intense public scrutiny that few consumer-oriented e-commerce sites endure. Only the likes of Amazon.com and Yahoo are probably watched more closely.

Next up, Wilson must condense his network onto a Palmtop. In October, the company announced that eBay will be available to users of the Palm VII. This leads the way for a wave of wireless Internet access devices. Likewise, the sensational success of eBay has caused the company to regionalize this year. It has now opened up about a dozen of sites that serve specific metropolitan areas. These sites have decentralized Wilson's architecture, giving him the complexity that only comes from widely distributed systems.

He's now also grappling with the age-old problem of integrating an acquisition. In April, eBay acquired Butterfield & Butterfield, the fourth-largest auction firm in the world. Strategically, this move gives eBay the prestige it needs to penetrate into higher priced items, globally.

Wilson's challenge: to ensure that its high growth rate doesn't topple the network reliability that he's established.
