High-Performance Software Load Balancer for Cloud-Native Architecture

Driven by increasing in the demand for cloud computing, providers are constantly seeking configuration mechanisms designed to simply install a reliable and easy-to-manage architecture—similar installing an operating system on computer using thumb drive. Accordingly, software components can be packaged into lightweight portable containers, then easily deployed managed through orchestration tools such as Kubernetes. Similarly, load balancers also containerized environments container, simplifying process of scaling or out according network status amounts incoming traffic. In this study, we implemented high-performance balancer that distributes traffic eBPF/XDP within Linux kernel, which via We compared performance proposed with iptables DNAT loopback based RFC2544 standard, performed tests simulating real-world patterns IMIX streams. Our experimental results indicate throughput is considerably better than DNAT; difference increased decreasing packet size. The between (representing theoretical maximum limit) was minimal.
