Programmatically create, provision, snapshot, delete and restore complex networks all in software. VMware NSX™ breaks through current physical network barriers, enabling data center operators to achieve order of magnitude better speed, economics and choice.

A transformation, not a transition

NSX delivers a completely new operational model for networking that breaks through current physical network barriers allowing data center operators to achieve order of magnitude better speed, economics and choice.

Just like server virtualization enables IT to treat physical hosts as a pool of compute capacity, the NSX approach allows IT to treat their physical network as a pool of transport capacity that can be consumed and repurposed on demand.

A virtual machine is a software container which presents logical CPU, memory and storage to an application. Similarly, a virtual network is a software container that presents logical network components – logical switches, logical routers, logical firewalls, logical load balancers, logical VPNs and more – to connected workloads.

Logical networks are programmatically created, provisioned and managed, utilizing the underlying physical network as a simple packet forwarding backplane. Network and security services are distributed and attached to VMs within a network. As a VM is moved to another host, these services stay attached to the VM and move with it. In addition, as new VMs are added to a network to scale an application, policy can be dynamically applied to the new VMs.

Businesses want to go fast

Businesses want to increase the speed of innovation, reduce time-to-market and drive the velocity of their business. NSX removes the operational barrier the network has become as IT strives to respond the business needs.

Programmatic provisioning reduces service delivery times from weeks to seconds. NSX transforms the operational model of networking, which combined with compute and storage virtualization delivers never before possible IT speed for the business.

The most disruptive, non-disruptive technology…Again!

Just like VMware for compute virtualization, NSX deploys non-disruptively on top of any existing physical network infrastructure and supports next generation fabrics and topologies from any vendor.

Because virtual networks reproduce the networking model in software, existing applications and workloads operate unmodified and operators use existing network monitoring tools. Troubleshooting tools can view and process virtual network traffic just as they would physical network traffic.

Automate Security Provisioning with VMware NSX

Leverage the NSX platform to automate security provisioning and share application context across virtual and physical security platforms. Network security features core to the NSX platform include:

  • virtual network isolation
  • multi-tenancy
  • segmentation
  • distributed stateful firewalling

NSX traffic steering and distributed policy enforcement at the virtual interface allows security teams to define and deliver familiar security services in a virtual network environment. This dramatically increases operational efficiency and service quality while maintaining separation of duties between server, network and security teams.

NSX has been deployed in full production, at scale, by several of the largest cloud service providers, global financials and enterprise data centers in the world. Companies like AT&T, NTT, Rackspace, eBay, and PayPal have virtualized their networks with NSX and are benefiting from the speed and efficiency the NSX network virtualization platform delivers.
