Project Calico's mission is to provide an open pure L3 approach to virtual networking for highly scalable data centers that integrates seamlessly with could orchestration systems (such as OpenStack) to enable secure IP communication between virtual machines, containers, or bare metal workloads.
Tigera provides secure networking and comprehensive protection for containers and Kubernetes. We are also the creator and maintainer of Calico Open Source, the most widely used container networking and security solution. Calico software powers more than 100M containers across 8M+ nodes in 166 countries, and is supported across all major cloud providers and Kubernetes distributions.
