Network virtualization is the abstraction into the software of network resources traditionally provided by hardware. Network Virtualization can combine multiple physical networks into one virtual software-based network or split biological networks into separate, independent virtual networks.
Types of Network Virtualization
Understanding the different types can help you decide which solution is best for your business. These solutions are not mutually exclusive;
many organizations use a combination of Network Virtualization Solutions.
Internal network virtualization:
Designed to replicate the functionality of a single system using software containers. This virtualization improves the overall efficiency of a single system by isolating services into separate containers and pseudo-interfaces.
External network virtualization:
Combine multiple local networks into one virtual Network to improve network efficiency. The aim is to increase the efficiency of a company’s bus network or data center. VLANs and network switches are the two main components of the external virtual network.
Benefits of network virtualization
Network virtualization enables organizations to significantly improve speed, agility, and security by automating and simplifying many operations related to maintaining data center networks and managing networks and security in the cloud.
Increased flexibility network
Virtualization shifts intelligence from specialized hardware to flexible software, increasing IT and business agility. Hypervisors use network virtualization to replicate network functions in software. Organizations can mix & match virtualized services to create their virtual network in seconds. That’s because everything built into the software. This level of adaptability is one of the main benefits of SDDCs and one of the main reasons.
Enhanced network security
Network virtualization improves security by acting as a building block for micro-segmentation, using fine-grained rules and network management to enable data center security. Micro-segmentation allows organizations to reduce the safety of each workload and prevent the spread of server-to-server attacks. When users build virtual networks, they remain isolated from each other until someone tries to connect to them. This isolation does not require physical subnets, VLANs, access control lists (ACLs), or firewall rules. Virtual networks are separate from real networks: This isolation prevents changes in one virtual network from impacting other virtual networks and protects the underlying physical infrastructure from attacks initiated by workloads in one of her virtual networks.
Dynamic network management
Network virtualization provides centralized management and dynamic provisioning and reconfiguration of network resources. In addition, computer resources and services can be directly connected to virtual network resources. That enables better application support, resource utilization, and efficient network traffic management.
