Great article—this gives a very clear and practical overview of how VMware VKS integrates with F5 BIG-IP and CIS, especially the breakdown of NodePort vs ClusterIP, CNI options (Antrea/Calico), and single-tier vs two-tier architectures. The real-world considerations around NSX networking, SNAT requirements, and multi-cluster traffic routing are particularly useful for teams designing production-grade Kubernetes ingress on VMware Cloud Foundation. Overall, it’s a solid reference for understanding how BIG-IP extends beyond basic load balancing into security, traffic control, and multi-cluster application delivery in enterprise Kubernetes setups.
