SUSE has chosen to add open source Calico container network interface (CNI) plugin as an option to Rancher Kubernetes Engine (RKE) 2. Calico provides highly scalable, high-performance and resource-efficient networking and security that works across multi-cloud and hybrid environments with support for multiple data planes, such as eBPF, Linux and Windows. With Calico integrated as part of RKE2, users can secure, observe, and troubleshoot their Kubernees environments across multiple data plane.
