What: Shares of Gigamon Inc (GIMO) were soaring today, closing up 12% after breezing past estimates in its second-quarter earnings report.

So what: The network-traffic specialist said it made an adjusted per-share profit of $0.30 in the quarter, up from $0.16 a year ago, and better than estimates at $0.24. Revenue jumped 46%, to $75.1 million, also topping expectations of $70 million.

The company has benefited from its close relationship with Amazon Web Services, and its cloud business should see revenue accelerate next year. CEO Paul Hopper said that "strong execution across the company" helped drive the impressive performance, noting, in particular, its first-to-market Security Delivery Platform.

Now what: In the last quarter, the company announced field trials of the Amazon Web Services Elastic Cloud Compute offering -- "the first visibility solution for information traversing with the public cloud." Gigamon's relationship with Amazon could prove to be lucrative as the AWS juggernaut is a fast-growing business set to hit $10 billion in revenue this year. The stock has more than doubled this year as the company has pushed further into the networking security market, which now makes up 60% of its revenue.

Gigamon did not issue guidance, but the strong demand for its products, and growth in cloud, should continue to push shares higher, as adjusted profits nearly doubled in the quarter.
