“Over the past four years, Docker has grown at an incredible rate,” said Solomon Hykes, Docker’s founder and chief technology officer, in a statement. “We are now seeing widespread traction in the developer community and the enterprise market.”

The company, founded in 2010 as dotCloud, has raised just over $180 million from such backers as Greylock Ventures, Sequoia Capital, and Insight Venture Partners.
