VMWare # NSX-T = VMware NSX-Transformers (officially “NSX-T Data Center”) ________________________________________ Simple Explanation NSX-T is VMware’s software-defined networking (SDN) platform. It lets you create, manage, and secure networks entirely in software — no need to rely on physical network gear for every change. Think of it as the “network virtualization” part of SDDC. ________________________________________ Key Points about NSX-T 1. Multi-Platform o Works not only with VMware vSphere (ESXi) but also KVM, bare metal, containers (Kubernetes), and public clouds. o This is why VMware created NSX-T — NSX-V worked only with vSphere. 2. Core Features o Logical Switches – Software-based networks for VMs/containers o Logical Routers – Routing between virtual networks without physical routers o Distributed Firewall – Security rules applied at the VM’s virtual NIC level o Micro-Segmentation – Isolate workloads without changing physical network o Load Balancing, VPN, NAT – All done in software 3. Use Case o You can create a new network segment in seconds without touching a single switch or cable. o Security rules follow the VM even if it moves to another ESXi host via vMotion. ________________________________________ Example Without NSX-T: • To create an isolated network for testing, you’d reconfigure VLANs on physical switches and update firewalls. With NSX-T: • You open the NSX-T Manager, click “Add Segment”, and the network is ready — no physical changes needed. ________________________________________ Purpose: • Faster network provisioning • Stronger, granular security • Multi-cloud and container-ready networking • Fits into SDDC as the network virtualization layer
