VMware NSX

VMware NSX is a virtual networking and security software product family created from VMware’s vCloud Networking and Security (vCNS) and Nicira Network Virtualization Platform (NVP) intellectual property.

NSX software-defined networking is part of VMware’s software-defined data center concept, which offers cloud computing on VMware virtualization technologies. VMware’s stated goal with NSX is to provision virtual networking environments without command line interfaces or other direct administrator intervention.

Network virtualization abstracts network operations from the underlying hardware onto a distributed virtualization layer, much like server virtualization does for processing power and operating systems. VMware vCNS (formerly called vShield) virtualizes L4-L7 of the network. Nicira’s NVP virtualizes the network fabric, L2 and L3.

VMware says that NSX will expose logical firewalls, switches, routers, ports and other networking elements to allow virtual networking among vendor-agnostic hypervisors, cloud management systems and associated network hardware. It also will support external networking and security ecosystem services.

 

USE CASES FOR NSX

Security 

NSX embeds security functions right into the hypervisor. It delivers micro-segmentation and granular security to the individual workload, enabling a fundamentally more secure data center. Security policies travel with the workloads, independent of where workloads are in the network topology.

Automation

NSX lets you treat your physical network as a pool of transport capacity, with network and security services attached to workloads using a policy-driven approach. This automates networking operations and eliminates bottlenecks associated with hardware-based networks.

Application Continuity

NSX abstracts networking from the underlying hardware and attaches networking and security policies to their associated workloads. Applications and data can reside and be accessible anywhere. Move workloads from one data center to another, or deploy them into a hybrid cloud environment.

Compliance

NSX enables micro-segmentation and granular security of workloads in virtualized networks, isolating sensitive systems and reducing both risk and scope of compliance. Use NSX to help ensure and demonstrate compliant operations with many regulations such as PCI DSS, HIPAA, FedRAMP, SOC, CJIS, DISA STIG, and more.
