Docker, Inc., the commercial entity behind the open source Docker project, today announced it has completed a $15 million Series B funding round led by Greylock Partners.

The funding will be allocated to product development and acceleration of Docker's rapidly growing ecosystem, as well as building out the company's commercial product and channels. Also participating in the round are Insight Venture Partners and existing investors Benchmark, Trinity Ventures and Jerry Yang.

'We are witnessing a fundamental disruption in the data center and application infrastructure stack. The next generation of SaaS and enterprise applications are being built for the cloud using process and container based technologies, thereby increasing performance, density, portability and flexibility,' said Jerry Chen, partner at Greylock. 'Docker has emerged as a key player in this exciting transformation, and is rapidly emerging as the standard for containerization.'

Since launching in March 2013, Docker has rapidly grown its ecosystem, receiving over 400,000 downloads, welcoming more than 300 contributors and gathering over 5,000 published 'Dockerized' applications in its public index. Companies such as Google, eBay, Yandex, Mailgun, CloudFlare and Baidu have publicly discussed their use or support of Docker, and Docker drivers have been accepted into the current release of OpenStack. Additionally, the company recently entered into a collaboration with Red Hat focused on bringing next generation Linux container enhancements to Red Hat Enterprise Linux and OpenShift platform-as-a-service.

Docker has also grown its executive team with three experienced industry leaders, naming Ben Golub as CEO in April, and hiring Roger Egan as senior vice president of sales and channels and James Turnbull as vice president of services in December. As part of the transaction, current Greylock partner and former VMware executive, Jerry Chen, will be joining the company's board of directors, bringing his extensive experience and knowledge of virtualization, cloud and IT management.

'The Docker ecosystem of people, products, platforms and partners is revolutionizing the way code is built, packaged and deployed,' said Ben Golub, CEO of Docker. 'With such huge market potential, we are thrilled to have both the board and the level of funding needed to pursue this opportunity aggressively. We are grateful that Greylock and Insight share our vision and have joined our efforts.'
