Calico Open Source is a networking and security solution for containers, virtual machines, and native host-based workloads.
Calico Open Source is a networking and security solution for containers, virtual machines, and native host-based workloads. Calico supports a broad range of platforms including Kubernetes, OpenShift, Docker EE, OpenStack, and bare metal services.
Whether you are using Calico's eBPF data plane, Linux’s standard networking pipeline, or the Windows data plane, Calico delivers blazing-fast performance with true cloud-native scalability. Calico provides developers and cluster operators with a consistent experience and set of capabilities whether running in public cloud or on-premises, or on a single node or across a multi-thousand node cluster.
Project Calico focuses on the following points.
Project Calico was created 6 years ago as an open-source networking and security project with an active development and user community. Calico Open Source was born out of this project and has grown to be the most widely adopted solution for networking and security for containers and Kubernetes, powering 2M+ nodes daily across 166 countries.
As adoption of containers and Kubernetes grew and organizations started using Kubernetes at scale, they began to encounter more advanced requirements for observability and security. Calico Open Source is a cutting-edge networking and security solution for containers and Kubernetes. The invention and continuous development of this solution would not be possible without the help of Project Calico’s 200+ (and counting) contributors around the world, ranging from private citizens to big tech companies.
Regardless of your team’s data plane choice you could use Calico whether you are on eBPF, standard Linux, or Windows.
Using Calico helps getting the best possible performance with lower CPU consumption so you could reallocate your resources.
Calico provides an extra layer of security with Calico network policy without losing the original reference implementation of Kubernetes network policy.
