The popularity of Zynga’s online gaming market has been explosive, almost exponential. They have marched virtually unopposed into near dominance of the social gaming market through deals with Google and Facebook. They’re the innovation engine behind such incredibly trendy games like Farmville and Frontierville. Farmville itself got the strange distinction of exceeding the userbase of Twitter last year.

At this year’s Oracle OpenWorld 2010, Zynga’s CTO, Catir Lee has let us all in some staggering statistics that outline the exact nature of the social gaming company’s market supremacy.

Zynga’s games and holdings transfer over a petabyte of data a day using their own specialized private/public cloud infrastructure. All of this data accomplishes a great deal of connectivity between players, which altogether exceeds over 3 million neighbor connections in games like Farmville.

Lee estimates that over 10% of the world’s Internet population has played a Zynga game—that’s over 215 million monthly visitors. And, he adds, in order to keep up with the ever-increasing traffic and usage the company adds almost 1,000 servers every week.

As a company, Zynga has been ever growing in size and stake, making new hires and inflating themselves through acquisitions of gaming and cloud oriented technology—like social gaming studios, mobile gaming platform companies, and the like. Their employee base has to keep up with the giant workload (such as adding those thousand servers a week) and maintaining their already heavily trafficked infrastructure.

Demand for Zynga games is massive and the trend doesn’t seem to be slowing. Casual social gaming is the current and next big thing.
