It often takes real money to move virtualization technology forward, which is why open-source virtualization vendor Docker is now raising new funds.
Docker announced today that it has raised $15 million in a new Series B round of funding led by Greylock Partners, with participation from Trinity Ventures, Benchmark and Insight Ventures. Total funding to date from Docker now stands at $26 million.
Docker as a company was originally known as dot Cloud and changed its name in 2013 to reflect a shift in strategy and to capitalize on the brand recognition of its open-source Docker container virtualization software efforts. Instead of using virtual machine hypervisors to virtualize applications, Docker is a container technology. The container approach leverage the existing host system’s operating system and virtualizes the application delivery, making for a potentially more efficient approach.
