CoreOS, based in San Francisco, is developing its own container technology called rkt (pronounced 'Rocket'), which competes with Docker's container format. The startup also develops a lightweight Linux distribution that aims to let organizations run a Google-like infrastructure in their enterprise data centers.
CoreOS Linux became available in China for the first time in early July, after Microsoft Azure, operated by local cloud provider 21Vianet, began offering it to customers.
In addition to releasing several of its technologies as open source projects, CoreOS also sells Tectonic, a commercial distribution of the combined Kubernetes (a container management platform developed by Google) and CoreOS stack.
CoreOS is active on the partnership front too. The startup teamed with Mirantis last August on a project to develop an enterprise-grade integration of OpenStack with Kubernetes.
CoreOS has raised $48 million in five funding rounds since starting out in 2013, and investors include Andreessen Horowitz, Kleiner Perkins Caufield & Byers, Sequoia Capital, Google Ventures and Intel Capital.
