How SD-WAN Simplifies Networking and Lowers Costs

Mar 31, 2020

Businesses of all sizes are embracing software-defined wide area networking (SD-WAN) in the IoT era, often due to its cost-saving qualities. Additionally, it also allows for much more simplified management of connectivity and digital resources. SD-WAN further provides high-level security and reliability, making it a strong consideration for any operation.

Comparing LAN with WAN

The two main types of networks are WANs and LANs (local area networks). A WAN consists of routers at each of its sites and requires manual configuration, which can lead to errors. In this type of environment, troubleshooting can be very time-consuming.

While LANs represent traditional ethernet connections for limited areas, a WAN allows for Internet connectivity outside of coverage areas wider than LANs. The emerging SD-WAN offers a more virtualized solution. While this concept has been around for a long time, the idea of a software-defined infrastructure is relatively new.

This modern method of networking works well with integration to new IoT technology. The result is a more efficient network that leads to greater productivity and less bottlenecks. Other key attractions to SD-WAN are that it is easy to use, and it simplifies complex connections through centralization.

The growth of cloud services and mobile devices has fueled the IoT revolution, which is creating higher bandwidth demands. This growing demand has put a strain on Internet traffic that connects central locations with branch offices over multiprotocol label switching (MPLS) connections. However, growing cost and complexity involving MPLS is causing businesses to rethink the WAN model.

Broadband is more cost-efficient than MPLS, whereas MPLS connections are more reliable at data transmission. The problem with traditional WAN is that it isn’t suitable for decision-making in real-time. And hybrid WAN solutions require too much configuration. When it comes to delivering mission-critical or sensitive data, SD-WAN has the edge.

Another key advantage of SD-WAN technology is that it creates one main pipeline that facilitates all active connections. Company policies based on network security, access and usage can be set or changed quickly, and then automatically enforced.

Major Business Benefits

SD-WAN solutions are spreading across various industries due to faster transmission speed and cost-effectiveness. They help meet the requirements of modern businesses, which include offering:

  • Lower costs
  • Less time involvement with configuration
  • Better network performance
  • More reliable connectivity
  • Greater operational efficiency

One way that SD-WAN cuts costs is by making more efficient use of bandwidth, while transferring traffic from MPLS connections to broadband links. Overall, it also reduces administrative and equipment costs. Additionally, since these networks use more simplified and automated configurations, more time can be spent on other matters. Instead of constantly reconfiguring devices, the system allows you to prioritize certain types of traffic by implementing policies.

At the same time, SD-WAN solutions can adapt as network changes, as they are useful for distributing loads over various links. For this reason, SD-WAN solutions not only enhance network performance, they also increase reliability of uptime. The reason they offer more secure conditions is because they use encryption and next-gen firewalls. Other security layers include web filtering and threat management.

SD-WAN technology can also streamline operations due to network functions virtualization. It allows users to access network services through software, making it possible to centralize controls for multiple devices. SD-WAN also allows for greater segmentation of data and applications so that only certain departments or branches can access certain data.

The benefits of SD-WAN are enormous because they resolve various problems posed by networks and bandwidth limitations. In the future, businesses will find more uses for SD-WAN, partly due to the proliferation of IoT devices and the need for monitoring various processes.

Essentially, SD-WAN has better policy-setting functions than earlier types of WANs. It also provides more advanced diagnostics and traffic analytics.
