Community-driven initiative integrates Project Calico and Flannel in a new startup home

At CoreOS Fest Berlin today, CoreOS and Tigera, a new San Francisco-based cloud networking company, announced a collaboration combining their two leading cloud networking solutions into a single open source project, Canal. Applying Project Calico’s industry-leading network policy enforcement capabilities to Flannel’s broad range of connectivity options, Canal represents the best-of-breed policy-based networking solution for cloud native applications. The project is being launched on a solid financial footing, with funding for Tigera coming from New Enterprise Associates.

Enterprises are increasingly building applications around a microservices architecture, with large numbers of highly dynamic containers deployed across a hybrid public/private cloud infrastructure, in combination with traditional virtual machine and bare metal workloads. Traditional networking and security solutions are not sufficiently scalable or flexible to meet the highly dynamic nature of these applications. The Canal project seeks to solve this problem by simplifying the network layer, weaving security policy into both the network fabric and the cloud orchestrator. By combining the best aspects of Calico and Flannel, the Canal initiative defines the new gold standard for cloud environments including Kubernetes, Tectonic, DC/OS, Apache Mesos, Docker Swarm, Apache Brooklyn, and OpenStack.

Resolutely committed to the community-driven principles of open source collaboration, Tigera will provide management and technical oversight for the Canal, Calico and Flannel open source projects, collaborating with CoreOS and all the existing project maintainers. Further, the San Francisco-based Calico team, formerly part of Metaswitch, is also transitioning into Tigera, ensuring continuity and full support for existing customers.

“The reason for creating the Canal initiative was simplicity itself,” said Andy Randall, CEO of Tigera. “The Calico and Flannel user communities kept requesting tighter integration of our projects. Canal is our way of saying, ‘yes,’ to those communities. Now, instead of two independently successful open source cloud native projects providing useful components of web-scale cloud networking, large enterprises will have a single go-to solution for deploying their applications and container workloads in fully secure private, public, and/or hybrid clouds.”

“Canal is a community-driven initiative that aims to deliver the best of breed networking solution for the cloud-native stack,” said Alex Polvi, CEO of CoreOS. “We are happy to announce this collaboration with Project Calico and the arrival of Tigera with the leading minds in containers at CoreOS Fest. In addition to providing ongoing Flannel engineering support to Canal, as part of our collaboration, CoreOS will be integrating Canal with Tectonic, the universal enterprise solution for Kubernetes.”

“Clearly when both customers and the open source community are actively searching for better, more scalable and more secure networking solutions, transferring Calico into Tigera, and enabling the Calico team to thrive as a laser-focused, independent startup was an obvious decision and a classic win/win for everyone,” said Martin Lund, CEO of Metaswitch.
