VMware NSX

The Network Virtualization Platform

Network Virtualization and the SDDC

VMware NSX delivers a completely new operational model for networking that forms the foundation of the Software-Defined Data Center. Because NSX builds networks in software, data center operators can achieve levels of agility, security, and economics that were previously unreachable with physical networks. NSX provides a complete set of logical networking elements and services—including logical switching, routing, firewalling, load balancing, VPN, quality of service (QoS), and monitoring. These services are provisioned in virtual networks through any cloud management platform leveraging the NSX APIs. Virtual networks are deployed nondisruptively over any existing networking hardware.

NSX Key Features

Switching

Enable logical layer 2 overlay extensions across a routed (L3) fabric within and across data center boundaries. Support for VXLAN-based network overlays.

Routing

Dynamic routing between virtual networks performed in a distributed manner in the hypervisor kernel, scale-out routing with active-active failover with physical routers. Static routing and dynamic routing (OSPF, BGP) protocols supported.

Key Benefits
  • Micro-segmentation and granular security delivered to the individual workload
  • Reduced network provisioning time from days to seconds and improved operational efficiency through automation
  • Workload mobility independent of physical network topology within and across data centers
  • Enhanced security and advanced networking services through an ecosystem of leading third-party vendors

AT A GLANCE

VMware NSX® is the network virtualization platform for the Software-Defined Data Center (SDDC), delivering the operational model of a virtual machine for entire networks. With NSX, network functions including switching, routing, and firewalling are embedded in the hypervisor and distributed across the environment. This effectively creates a “network hypervisor” that acts as a platform for virtual networks and services. Similar to the operational model of virtual machines, virtual networks are programmatically provisioned and managed independently of underlying hardware. NSX reproduces the entire network model in software, enabling any network topology—from simple to complex multitier networks—to be created and provisioned in seconds. Users can create multiple virtual networks with diverse requirements, leveraging a combination of the services offered via NSX to build inherently more secure environments.
