In the last decade, companies and organizations have rapidly been adopting network virtualization (NV) in an effort to take advantage of the flexibility offered by software-based computing and storage resources. With software-defined networking (SDN) and network functions virtualization (NFV) promoting decoupling of the control and forwarding planes, more emphasis has been put on NV as of late. For example, after VMware acquired Nicira in 2012, it developed VMware network virtualization.
VMware Network Virtualization and VMware NSX
A virtual network built with VMware NSX is a software container that offers logical network pieces to connected workloads. These logical networks are created and managed programmatically by using the underlying physical network as a packet forwarding backplane, allowing for network and security servers to be appropriated and attached to virtual machines (VMs) within a network. As the VM moves from host to host, these services will remain attached to it and go where it goes. VMware says its network virtualization can help data center operators achieve better speed, economics, and choice.
VMware NSX claims to lower application provisioning times down considerably, from months to minutes. VMware network virtualization is also said to boost data center security building security directly into the data center infrastructure. This allows users to deploy advanced partner services to increase protection and reduce risk.
VMware Network Virtualization Benefits
VMware NSX is said to offer the following advantages for customers:
- Agility: limits time of provisioning from weeks to seconds.
- Cost: reduces both OpEx and CapEx with automation that eliminates manual configuration and streamlines network hardware requirements.
- Choice: operates on any hypervisor, any network hardware, and integrates with any cloud management platform.
