GV, formerly Google Ventures, lead a $28 million Series B funding in CoreOS, which deploys, manages, and secures software containers. Others participants included Intel Capital and existing investors Accel, Fuel Capital, Kleiner Perkins Caufield & Byers and Y Combinator Continuity Fund. CoreOS’s total funding to date is $48 million.

Press Release

In validation that hyperscale, container-enabled infrastructure will lead the next computing phase of enterprise companies, CoreOS, Inc. today announced it has received $28 million in Series B funding to support rapid expansion from a consortium of investors led by GV (formerly Google Ventures). Intel Capital participated in the round, as well as existing investors Accel, Fuel Capital, Kleiner Perkins Caufield & Byers (KPCB), Y Combinator Continuity Fund and others, bringing the company’s funding to date to $48 million.

CoreOS, a leader in deploying, managing and securing software containers, will use the additional funding to continue development of its solutions that enhance delivery of Google’s Infrastructure For Everyone Else (GIFEE), as well as to grow its team in the United States and Europe, hiring for its offices in San Francisco, New York and Berlin.

“For sophisticated enterprises, the inclusion of a container-based approach is inevitable,” said Dave Munichiello, General Partner at GV. “Software containers empower development teams to focus on building great applications without regard for the underlying IT infrastructure. CoreOS’s Tectonic product packages Google’s Kubernetes for enterprises, enabling them to run applications seamlessly across public and private clouds and their own data centers. With CoreOS, now the rest of the Fortune 500 has access to a fully-supported version of the same secure, resilient, highly-available approach that the best web-scale businesses use daily.”

CoreOS plans to continue building and delivering its full enterprise solution Tectonic, the enterprise Kubernetes distribution for running and managing application container clusters, and the Quay container registry. CoreOS will continue leading development of its open source projects that are securing the Internet including CoreOS Linux, the lightweight Linux operating system; etcd, the distributed, consistent key-value store; rkt, the container engine alternative to Docker; and Clair, the container image security analyzer. These key components developed by CoreOS in collaboration with the greater open source community are a part of delivering GIFEE to enterprises.

Tectonic, the completely supported technology stack for deploying containers in production, is built on CoreOS Linux and the Kubernetes cluster orchestrator and packages an array of tools for deploying, monitoring, and managing applications and infrastructure. With support from Intel, Tectonic will help make OpenStack on Kubernetes ready to deploy and manage for the enterprise.

“Hyperscale build-outs have been a key accelerator of server volume growth in recent years, and next generation applications is one key workload helping drive that growth. We find enterprise customers are increasingly interested shifting their focus from maintaining legacy applications to developing new applications and Web services using modern infrastructure software,” said Al Gillen, group vice president, enterprise infrastructure at IDC. “Standing up modern applications requires a full infrastructure software stack that includes, but goes well beyond container packaging technology. More complete solutions, such as those CoreOS offers, help to unlock this new class of capabilities and benefits for leading enterprises to run their business.”

“We are in the middle of an important transition in the next major phase in enterprise computing since virtualization and cloud, where enterprises are on the path to embracing Google-style infrastructure,” said Alex Polvi, CEO of CoreOS. “Kubernetes is on point to be as ubiquitous as Linux. With this investment, CoreOS is at the forefront of bringing GIFEE to enterprises by providing the most advanced and secure Kubernetes distribution.”

“Enterprises are looking to adopt some of the IT best practices of hyperscale cloud providers to deliver lower cost of ownership and high agility,” said Jason Waxman, corporate vice president of the Data Center Group at Intel Corp. “Intel’s investment and collaboration with CoreOS will accelerate the efficiency, security, and consistency of hyperscale computing for the broader industry.”

CoreOS is celebrating its open source community at CoreOS Fest in Berlin, May 9-10, and San Francisco, May 9.
