In the tech world, networks are one of the most important assets for a business. A network is a grouping of interconnected devices that interchange resources and data from one data point to another. A connection is established between these devices by using cables or a wireless medium. Networks can take a lot of real estate and hardware which can become a headache for companies. To avoid network and time management issues businesses can utilize network virtualization that can help them increase network stability and save precious time. In this blog, we are going to understand why a business should consider switching to a virtual network.

What is Network Virtualization?

Network virtualization is a process of combining the existing hardware networks with software-based networks to virtualize the network used by a business. Network Virtualization can combine more than one physical network to make a single virtual network or use one physical network to make multiple virtual networks which can help in network security. The virtual network can also be used to connect virtual machines and move them from one place to another without configuration. 

How does Network Virtualization Work?

Virtual networks work differently from the traditional network infrastructure. Rather than having big hardware devices it uses relatively less hardware and more software integrations. This makes virtual networks easier to use and store as they take less space for storage. Network virtualization allows you to:

Enhance Network Security:

Virtual networks enhance security by implementing segmentation measures that separate different workloads from one another. This reduces the chances of network hijacking and secures the overall virtual machines and containers.

Configuring a Virtual Network:

Traditionally, the creation and configuration of a network is a complex task conducted by IT professionals. The use of virtual networks makes it easy for businesses to configure the network. It is as simple as downloading software on a device. The process is made easy by automating tasks that were once done manually and were time-consuming.

Seamless Workloads:

Virtual networks are not tied up by specific hardware which makes it easier for administrators to migrate virtual machines and containers among servers without affecting the connectivity of the underlined server.

Why is Network Virtualization better than the Traditional Network?

Traditional networks take up a lot of space and have complex components. In contrast, virtual networks offer reliable solutions with the latest configurations. Virtual networks are better than the traditional in these areas:

Flexibility and Scalability:

Network virtualization tends to be more flexible than traditional options as it provides flexible options when it comes to additional requirements regarding scalability in a business quickly. As the traditional solutions require physical devices they are harder to source and complex to deploy it is easier for a business to have a network that is highly flexible and scalable.

Security and Efficiency:

Virtual networks exceed traditional networks by helping organizations enable micro-segmentation and isolated workloads that prevent a lateral network threat in the system. It also increases efficiency through task automation and centralization of controls which helps companies to do better resource utilization and improves the overall network performance.

Cost Effectiveness:

Network virtualization helps organizations to save costs. As the whole setup does not require expensive hardware components, this reduces the overall costs of the network infrastructure. It also optimizes resource usage to make sure that the cost is kept to a minimum.

Disaster Recovery:

Traditional networks have a very prolonged and complex data backup process requiring an IT specialist and specific hardware devices. Virtual networks are integrated with clouds to store valuable server data in the event of a system failure, the data can be recovered instantly from the cloud and the server can be stabilized quickly.

Importance of Network Virtualization:

Network virtualization is transforming how businesses develop and maintain their enterprise networking practices. These practices align effectively with today’s business needs. It supports integrating cloud-based applications, an integrated workload approach, and improved security measures. Companies can use network virtualization to get a secure, upgradeable, scalable network adaptable to this ever-changing tech world. Companies like VMware, Fortinet, and Citrix provide virtualization solutions that tick all the boxes discussed above.

Challenges of Network Virtualization:

Going virtual is a huge advantage in today’s IT market. It is a positive change if a company realizes the importance and benefits of virtual networks and applies these solutions in their environment too. In this context, there are some challenges companies need to overcome to make sure they undergo a smooth adoption.

Employee Training:

To implement virtual networking systems accurately firms should ensure that the IT department is prepared for the change. Firms must provide proper training and make officials take certification programs that can become an important part of the successful adoption.

Infrastructure Requirements:

To achieve the full potential of network virtualization, a company must ensure they have the correct infrastructure that can house such a network. If the underlying infrastructure is not compatible then the network may experience issues while handling the flux of traffic and latency issues.

Complexity of Management:

Endpoint management becomes difficult as network virtualization adds complex tasks for administrators. A way around this is to provide administrators with powerful tools and processes that can help track and manage virtual machines.

Network Virtualization Tools

Several tools out there help you virtualize your network in each aspect whether it is security, devices, integration, management, etc. Selecting the right tool is essential for a business as this reflects the future of the company. Here are two distinct tools with features that might assist you in attaining your organizational goals. 

1. VMware NSX

The VMware NSX is an advanced network virtualization tool that can help businesses in the areas of logical networking, security, automation and management, and much more. It provides logical switching and routing along with VPN services to implement secure Layer 2 and Layer 3 connections. It also provides micro-segmenting and firewalling to secure the network from threats. The API integration can help with the pragmatic configuration using API. 

1. Micro Focus Network Operations Management

The Micro Focus Network Operations Management (NOM) is a collection of tools that provide management and oversight of your network infrastructure. It uses network visibility, configuration management, and network security to ensure the virtualization process is streamlined and efficient. It enhances policy, performance, and fault management to secure the network and the infrastructure. In these tools configuration management is automated to reduce human errors in the virtual network. The tool provides real-time monitoring of the network performance and health to analyze any issues and rectify them on the spot. This tool saves a lot of money for organizations as they employ automation and new ways of doing things.

Conclusion:

In conclusion, network virtualization is a way to manage network through a software-based solutions. This reduces the complex hardware integrations and maintenance minimizing deployment time and streamlining network-related processes. It offers a powerful solution to businesses that need scalability, flexibility, and security in their processes with reduced costs. Once a firm understands the benefits, concepts, and challenges of virtualization it can make an informed decision on whether network virtualization is the best fit for their platform or not. Technology is evolving at a steady pace and in due time network virtualization will become a crucial part of building a future of secure and efficient networks.
