modification) Virtual Networks VMware NSX Network Virtualization Platform Any Network Hardware Any Cloud Management Platform VMware vSphere Logical Switching– Layer 2 over Layer 3, without dependencies on the physical network Logical Routing– Routing between virtual networks and physical, East-West and North-South Optimized Logical Firewall – Distributed Firewall, Kernel Integrated, High Performance Logical Load Balancer – Application Load Balancing in software Logical VPN – Site-to-Site & Remote Access VPN in software NSX API – RESTful API for integration into any Cloud Management Platform
Features • Remove hairpins and bottlenecks in routing and firewalling • Line rate performance with distributed scale out architecture Scale & Performance • Create on demand networks to speed up application provisioning Use Cases L2 L2 Tenant A Tenant B L2 L2 L2 Tenant C L2 L2 L2
• L2 Bridge to Cloud • Broadcast support Features • High Performance – AES-NI acceleration • 2 Gb/s throughput per tenant Scale & Performance • Cloud On-boarding • Cloud Bursting Use Cases Internet/ WAN L2 VPN L2 VPN VM VM VM

1:1 mapping between itself and a vCenter Server Features • Provides the management UI and API for NSX • Secures control plane communications Role • Managers and configures Controller Cluster via REST API and hosts via a message bus. • Manages and deploys NSX Controller, NSX edge virtual appliances and the initial vSphere web client plugin Functionality NSX Manager vCenter Server
Logical Router network information to hosts Features • Controllers are clustered for scale out and HA • Information is sliced across nodes for resiliency Scale & Performance • Remove dependency on Multicast on physical transport • Suppresses ARP broadcasts across VXLAN segments.
