The essential guide to VMware NSX SDN technology

Review the fundamentals of the VMware NSX SDN technology, its slate of features and what the future holds for VMware's new flagship product.


VMware's NSX network virtualization technology gives IT administrators the ability to virtualize network components without manual configuration. They can use VMware NSX software-defined networking (SDN) technology to manage networks at the hypervisor level, and they can use software to provision, organize and secure enterprise-scale networks.

NSX is central to VMware's strategy as it shifts from server virtualization to network virtualization. VMware NSX SDN capabilities play an important role in VMware's software-defined data center initiative and its cloud computing services. VMware NSX SDN features include network functionality built into the hypervisor, dynamic virtual network management, heightened network security and powerful automation.

Explore this essential guide to get a foundation of NSX's capabilities, to learn the extent of its features, to study its implementations and to plan for its future.
