Docker, the San Francisco startup that sells application container technology and management tools around it, meant to enable any application to run on any type of infrastructure, is in end-game discussions on a funding round that will range from $40 million to $75 million, GigaOm reported citing two anonymous sources.
The sources also told GigaOm that the company has been valued at about $400 million.
It will be several weeks before the round is closed. If successful, it will be Docker’s biggest funding round to date. It has raised $26 million so far, closing its most recent $15 million Series B earlier this year.
The company has been in existence under its current name for a few months longer than a year. It started as dotCloud, providing Platform-as-a-Service, and developed what served as the basis for Docker to enable the PaaS.
One year ago, however, it open sourced the Docker container technology and renamed itself. Earlier this week it announced that it had sold the dotCloud PaaS business to the German company called cloudControl.
A Docker-containerized application can be deployed on bare-metal servers, in a variety of clouds or on a PC. The application can also be easily moved from one infrastructure stack to another.
Docker 1.0, the first production-ready release, came out in June. The company has enjoyed support from the likes of Google and deployments by the likes of eBay, Spotify and Yandex.
Docker CEO Ben Golub told us in an interview recently that there was interest in the technology from many large banks, healthcare companies and enterprises.
In addition to the container technology itself, the company is working on management tools for it, including tools that enable multi-container applications. Last month it acquired a company called Orchard, which provides hosted cloud-based Docker and has a container orchestration tool called Fig.
