How SD-WAN is Revolutionizing Internet-Leased Line Connectivity for Remote Workers

The rapid transition of the global business environment into digitized virtualization has increased the demand for reliable and secure network connectivity. And these cloud-based businesses are increasingly deploying remote workforce to optimize operational excellence. But the dramatic and sudden shift to a remote workforce has led to many challenges. The primary challenge is ensuring remote workers access reliable and secure internet connectivity. A popular option for providing steady, uninterrupted connectivity is using internet leased lines (ILL).

What are internet leased lines?

A leased line is a dedicated internet connection that provides a business with a private, high-speed, low-latency internet connection. Leased lines are typically used by businesses that require a reliable and high-speed connection for mission-critical applications, such as video conferencing, VoIP, and file transfer. They are also commonly used by businesses with multiple remote workers that need to connect to the company’s network.

At the remote worker end, leased lines are dedicated, with high-speed internet connections leased to a single user, providing a dedicated, high-speed internet connection separate from the public internet. This makes them ideal for businesses that need to transfer large amounts of data, such as video or audio files, or for businesses that need to ensure that their internet connection is always available and secure.

However, as more and more companies adopt remote working, the traditional leased line model is becoming increasingly difficult to manage and maintain. ILLs are often expensive and can be difficult to set up. Additionally, they are typically only available in certain areas, which can limit their usefulness for remote workers who may be located in more rural areas.

This is where Software-Defined WAN (SD-WAN) comes in. SD WAN is a revolutionary technology that allows businesses to manage and optimize their network connections through software rather than hardware. This makes it much easier for businesses to manage their network connections and ensure that their remote workers have the necessary connectivity.

What is SD-WAN?

SD-WAN is a software-based networking solution that allows businesses to manage and optimize their WAN connections. It uses software to control the routing of network traffic, making it possible to adjust traffic paths based on real-time network conditions dynamically. This allows businesses to prioritize different types of traffic and ensure that critical applications are given priority over less important ones.

The core capability of SD-WAN is using any of the available internet connections, be it broadband or cellular, to combine into a single, unified WAN. Therefore, traffic can automatically move to the next available connection when one connection fails without interruptions. Thus businesses have a resilient, always-available network, which is especially important for remote workers.

How SD-WAN is Revolutionizing ILLs

Traditional internet leased lines have several limitations that make them less than ideal for remote workers. For one, they are often expensive and can be challenging to set up. Additionally, they are typically only available in certain areas, which can limit their usefulness for remote workers who may be located in more rural areas.

On the other hand, SD-WAN is more flexible and cost-effective than traditional ILLs. It allows businesses to use multiple internet connections, such as broadband and cellular, to create a single, unified WAN. If one connection goes down, traffic can be automatically routed over to another connection without interruption. This provides businesses with a more resilient and reliable network connection, which is especially important for remote workers.

SD-WAN uses a new approach to managing available internet leased lines and other options with prioritization. The technology to recognize services that need intense internet, like video conferencing or VoIP, are prioritized, thus ensuring these mission-critical applications are always connected. This ensures remote workers have the necessary bandwidth to perform their tasks and maintain productivity.

SD-WAN ensures secure connections for remote workers. SD-WAN solutions typically include built-in security features, such as VPN and firewall capabilities, that can help protect remote workers from cyber threats. This is especially important given the increase in cyberattacks targeting remote workers.

How are businesses benefitting from SD-WAN and ILL? 

Improves Resilience

One of the main benefits of SD-WAN is converting a network into a reliable, resilient network that connects remote workers. The default technology of using multiple internet connections, such as broadband and cellular, creates a unified WAN for businesses. Hence there is never an interruption in network service since the switch to steady connectivity is automatically and programmatically made. Thus, remote workers have a consistent and reliable internet connection, essential for maintaining productivity.

Prioritization of Traffic

Businesses can leverage the SD-WAN capability to prioritize traffic. Thus critical applications – video conferencing and VoIP – will always have connectivity over low-internet consuming applications. This ensures remote workers have the necessary bandwidth to perform their tasks and maintain productivity.

Enhanced Security

SD-WAN solutions typically include built-in security features, such as VPN and firewall capabilities, that can help protect remote workers from cyber threats. This is especially important given the increase in cyberattacks targeting remote workers.

Cost-Effectiveness

Compared to traditional ILLs, SD-WAN is more cost-effective. It can be easily and quickly deployed without expensive hardware and complex configurations. Additionally, it offers more features and capabilities than traditional ILLs, making it a more cost-effective solution for businesses.

Conclusion

The global shift to remote work has placed unprecedented demand for reliable and secure internet connectivity. Traditional internet leased lines have been efficient solutions for on-premise businesses thus far. But new work processes like remote work need more than simple internet leased lines can offer. Businesses are looking at new solutions like SD-WAN to provide their remote workers with a dedicated and high-speed internet connection. It is more flexible, cost-effective, and reliable and provides secure connections for remote workers. It truly has revolutionized the way we think about internet leased lines. It has become the go-to solution for businesses looking to support remote workers.
