VCF NSX 9.1: How Intelligent Networking Becomes the Private Cloud Control Fabric

This article explores how VMware Cloud Foundation (VCF) NSX 9.1 redefines networking as a private cloud control fabric. It explains the shift from traditional overlay segments to a governed service model where application teams consume Virtual Private Clouds (VPCs), subnets, and gateways, while provider, security, and operations teams manage physical integration, segmentation, and health monitoring. Key features discussed include flexible VPC connectivity, distributed and centralized services, VPC Network Span, enhanced transit gateway behavior, IPAM integration, and deeper observability. The article also notes that some advanced security, compliance, and load-balancing capabilities remain separately entitled, emphasizing the need to validate architecture and licensing together. It provides a conceptual operating model for understanding the image, breaking down each zone's architectural meaning and operational questions.
