Software Defined Network
Network virtualization
The NSX network virtualization approach, like server virtualization for the compute layer, allows data center operators to view their physical networks as a pool for transmission capacity that can be used or change the use if needed. In this approach, just as the virtual machine is a container for software, the logical CPU provides memory for the application, the virtual network is a container for the software that provides logical network factors for connected workloads, switches, routers, and firewalls, load balancers, VPNs and more.
Security and virtualization of VMWare NSX
By NSX technology , organizations get not only security, agility and speed, but also better economic aspects, flexibility, and power to choose.
Network virtualization platform
VMware NSX is one of the leading platforms for network virtualization, Network Virtualization, which provides the operating model of a virtual machine to the network. Virtual networks, like virtual machines, are programmatically prepared and managed independently of the main hardware. NSX recreates the network model in software and simplifies the ability to create and prepare any topology from simple networks to complex Multi-Tier networks. This technology provides a set of logical network services and factors such as firewalls, load balancers, VPNs, switches, logical routers, and workload security. In addition, users can create separate virtual networks by customizing these features.
Important features of NSX
Logical Switching, NSX Gateway, Logical Routing, Logical Firewall, Logic Load Balancer, Logical VPN, NSX API
Uses of NSX
Security
Providing a secure infrastructure for delivering a Zero-Trust security model
Securing virtual servers and desktops
Data Center Automation
Accelerating network preparation
Simplifying the provision of physical and virtual services
Simplifying DMZ changes
NSX’s respond to IT challenges
Micro-segmentation technic for security
Control and security of firewall for traffic by the East-West pattern, in data centers, minimize the risk and the effect of data security violation and economizes in finance costs up to 68%.
Using IT to automate IT: decrease of manual failure
Manual Actions and preparation cycle time and network management decreases, meanwhile, releasing services and delivery time of new programs to the market, will be accelerated. Therefore, it will be economized in finance costs, 56% up to 86%.
Retrieving and optimizing IT – flexible infrastructure
Optimizing the structures of Leaf/Spine modern networks, bare metal switches, open network and other data centers, will be accelerated and it will be economized in finance costs, 66% up to 88%.
Disaster recovery
Availability of service in Cloud scale, decrease in risk, and effects of non-programmed disruptions causes in economization the cost of $690000 up to tens of million dollars in each occurrence.
Continuity of applications
With NSX, networking and security can easily be extended to eight vCenters across or within the data center. This technology, along with vSphere, ensures that the network operates the same on sites, and that firewall rules remain unchanged. So a similar view is created on websites.
NSX Cross vCenter Networking helps create an Active-Active data center.
