VMware NSX is the network virtualization and security platform that enables VMware’s cloud networking solution with a software-defined approach to networking that extends across data centers, clouds, and application frameworks. With NSX, networking and security are brought closer to the application wherever it is running, from virtual machines (VMs) to containers to physical servers. Like the operational model of VMs, networks can be provisioned and managed independent 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 through NSX or from a broad ecosystem of third-party integrations, ranging from next-generation firewalls to performance management solutions, to build inherently more agile and secure environments. These services can then be extended to various endpoints within and across clouds.
VMware NSX delivers a new operational model for networking defined in software, forming the foundation of the software-defined data center (SDDC) and extending to a cloud network. Data center operators can achieve levels of agility, security, and economics that were previously unreachable when the data center network was tied solely to physical hardware components. NSX provides a complete set of logical networking and security capabilities and services. These include logical switching, routing, firewalling, load balancing, virtual private network (VPN), quality of service (QoS), and monitoring. These services are provisioned in virtual networks through any cloud management platform leveraging NSX APIs. Virtual networks are deployed nondisruptively over any existing networking hardware and can extend across data centers, public and private clouds, container platforms, and physical servers.
The main use cases of VMware NSX are as follows:
