Make Underlay CNI Powerful and Simple

Explore the intricacies of underlay CNI solutions in this 32-minute conference talk presented by Lan Weizhou and Qiuping Dai from Daocloud at a CNCF event. Delve into the challenges faced by low-latency applications, traditional host applications migrating to the cloud, and storage components requiring independent networks for data transmission. Examine the limitations of existing open-source options like macvlan, SRIOV, and ipvlan CNI projects, which lack crucial functionalities such as IPAM and clusterip communication. Investigate the complexities of projects like multus and their inability to address routing tuning and IP allocation across multiple network interfaces. Learn about Spiderpool, an IPAM solution that integrates with various CNI technologies to overcome these challenges, offering features like IP dual-stack support, fixed IP for applications, IP recycling, and conflict resolution. Gain insights into how this integration results in a new, more robust Underlay network solution for cloud-native environments.
