Design and Implementation of High-Performance Software Load Balancer for Cloud Service

With the growth of cloud computing platform scale and the surge of cloud tenant traffic, it will undoubtedly bring huge challenges to the load balancing of cloud service clusters. In order to achieve the load balancing of high concurrent tenant traffic balance to the appropriate service node, the paper proposes a DPDK-based software load balancer to deal with and optimize the traditional software load balancer's low performance and low reliability limitations. We also designed a health check mechanism for cloud computing, which can continuously and stably check the health status of service nodes under continuous overloaded business traffic. The experimental results show that the software load balancer designed in the paper has high performance, high availability, high scalability, and can meet most of the cloud computing service requirements.
