Cisco has re-entered the load balancing market after abandoning it in 2012, now leveraging open-source software developed by Itsovaient, acquired in 2023. Cisco's move comes in response to customer demands for load balancers for Kubernetes containers amid rising costs from VMware licensing changes. The new Isovalent Load Balancer is built on eBPF technology, renowned for its efficiency, capable of processing ten million packets per second. This technology is rooted in developments by Google and Meta, ensuring robust performance across varied infrastructures.
'Cilium runs as a program in eBPF, which effectively allows the creation of plugins to the Linux kernel. eBPF can process ten million packets per second on a single Intel core.'
'The result of those decisions is a load balancer using tech that both Google and Meta have proven can run at scale.'
