Network Virtualization vs. Software-Defined Networking (SDN)
As with server virtualization before it, network virtualization is a transformative architecture from VMware that overcomes previous limitations to deliver unprecedented performance, flexibility and economics.
In contrast to software-defined networking (SDN), in which hardware remains the driving force, VMware technology truly decouples network resources from underlying hardware. Virtualization principles are applied to physical network infrastructure, abstracting network services to create a flexible pool of transport capacity that can be allocated, utilized and repurposed on demand.
In a close analogy to the virtual machine, a virtual network is a software container that presents logical network components—logical switches, routers, firewalls, load balancers, VPNs and more—to connected workloads. These virtual networks are programmatically created, provisioned and managed, with the underlying physical network serving as a simple packet-forwarding backplane. Network and security services are allocated to each VM according to its needs, and stay attached to it as the VM moves among hosts in the dynamic virtualized environment.
NSX. Transformative Benefits with Non-Disruptive Deployment
VMware’s network virtualization platform,
NSX, deploys on top of existing physical network hardware and supports the newest fabrics and geometries from all vendors. Existing applications and monitoring tools work smoothly with NXS without any modifications.
NSX reduces delivery time for network topologies and security services from weeks to seconds, shrinks OPEX and CAPEX, operates on any hypervisor and works with all network hardware. The platform is currently in full production deployment at some of the world’s largest cloud service providers, financial firms and enterprise data centers.
