SD-WAN is the latest technology that works by separating applications from the underlying network services. It mainly uses software to perform all the networking tasks of the business. This service helps in optimizing the traffic flows for performance. By replacing traditional WAN, this solution allows businesses to route large portions of their traffic over cost-effective service. The issues that cannot be solved with traditional WAN will get fixed with the deployment of SD-WAN. Ultimately, the main objective of SD-WAN is to deliver a secure, and simple cloud-enabled WAN connection. So, yes, SD-WAN fulfill the inefficiencies of traditional wan.
Is it better to switch to SD-WAN from legacy WAN architecture?
These days, most businesses are adopting digital transformation more quickly than anything else. The digital evolution helps them in making networking secure and work faster. Online meetings and remote work have become the new normal. Even, different applications are migrating to the public cloud and numerous services can be used online. But, at some point, traditional WAN can interrupt various business functions because of its inefficiency.
For establishing a connection between remote locations, traditional WAN is not a convenient option. It might cause cyber risks and data theft. Also, traditional Wan requires a huge amount for networking operations. So, we can see various inefficiencies of traditional WAN architecture that
This is why, most businesses prefer switching to the latest WAN architecture such as SD-WAN. It helps in managing infrastructure more efficiently and cutting networking costs. The traditional wide-area network (WAN), on the other hand, was linking users at distant locations to applications from the business’s data center.
An insight into traditional WAN architecture:
Let’s now examine traditional WAN technology in more detail. Also, traditional WANs rely on MPLS as it ensures an effective flow of network traffic. It also can prioritize the data traffic on the network.
Traditional WAN is entirely dependent on physical network components and effective network traffic flow enabled by Multi-Protocol Label Switching.
In traditional WAN technology, there will be more hardware, devices, applications, and circuits to route IP services. Because of this, there will be many layers of hardware installation and a lot of effort by the IT team.
However, with the deployment of traditional WAN, you’ll surely get to witness some inefficiencies. But the good thing is that it can be controlled by migrating to the SD-WAN technology.
Ways in which SD-WAN covers all the inefficiencies of old WAN architecture:
1. In terms of performance
There are so many services, and applications that can be easily prioritized by SD-WAN. From Voice over Internet Protocol to many real-time services, all these are directed via an effective path in the SD-WAN network. As a result, the overall performance of the network is increased. But, you won’t witness an enhanced performance in the older WAN architectures. Businesses can easily improve performance in terms of speed with their dependability with SD-WAN.
The SD-WAN network architecture makes sure that all users have access to the same network resources. Also, this latest WAN technology combines various features such as VPN, SDN, and NFV that also boost the network performance.
With the help of SD-WAN, IT teams can assist in lowering packet loss and latency issues. This ultimately improves employee productivity and overall operation. The performance can be achieved by facilitating important applications through high-performance connections.
2. In terms of security
The deployment of SD-WAN also ensures enhanced security features to protect the overall data of the business. SD-WAN solution comes with several latest features such as DNS filtering, IDS/IPS, and secure encryption that is considered good for the business.
These in-built characteristics of SD-WAN aid in defending against threats from hackers. Along with this, many other security features are not available with traditional networks. This means that the implementation of SD-WAN can handle security through a number of applications and devices at each branch office.
Due to the integrated encryption features of SD-WAN systems, only authorized users will be able to access the data. Additionally, authentic users can view the assets that are linked to the corporate network. One of the good things about SD-WAN is that it prevents high-risk traffic from ever entering the network. In this way, SD-WAN benefits businesses by keeping their data safe and secure.
Is the SD-WAN solution worthy of investment?
Yes, SD-WAN benefits organizations from all business verticals. From healthcare to manufacturing, you can see the application of SD-WAN in many sectors. All these are possible because of the in-built features and benefits of software-defined WAN. Are you also looking for SD-WAN vendors for your business deployment? If yes then Infinity Labs is the one-stop destination that you can go for.
Can SD-WAN solve security concerns?
SD-WAN has several built-in features of encryption that prevent any sort of data theft. Also, it enables only authorized users to get access to the network. Because of SD-WAN, cyber risk is reduced to a great extent. As traditional WAN is inefficient in meeting the needs of security, organizations rely on SD-WAN for its various encryption features.
To sum up
This blog just described what SD-WAN is and why businesses should think of choosing it over traditional WANs. With the implementation of SD-WAN, there’s a possibility of removing all the inefficiencies of traditional WANs. After reading this, you will be able to comprehend the significance of SD-WAN and find out whether it is suitable for your business or not.
