SD-WAN: The Definition and The Advantages for Your Business

In the technology era, utilizing some software to make your business run efficiently is more common. Some different software is connected to each other in the different geographical areas of your branch offices. 

Sometimes, companies have to budget huge amounts of costs to build the technology infrastructure for their business. Software-defined wide-area networks (SD-WAN) can help you to manage the tech infrastructure.

What is SD-WAN and What’s the Differences with the Traditional WAN?

As the name states, software-defined wide-area networks can simplify network operation of wide-area networks (WAN) through software. 

The SD-WAN definition is a system that makes it possible to manage and control data centers and remote branches or cloud instances. 

It is more advanced than WAN, which uses Multiprotocol Label Switching (MPLS) as a connectivity method. 

The MPLS method in traditional WAN can make you assign preferences based on SLA guarantees and determine timelines for traffic delivery. It can leverage internet-based backup as another transport if the primary path is unavailable.

Utilizing the software in SD-WAN allows simplifying the integrations of the data over time. It can be more flexible than traditional WAN, because you can control and manage it through the software. 

The flexibility of SD-WAN is one of its chief features. SD-WAN makes your business possible to manage multiple connections from each MPLS to broadband to LTE. Besides that, SD-WAN has the ability to segment, partition and secure the traffic of WAN.  

The Benefits of SD-WAN for Your Business

The complexion of data and tech infrastructure needed neat protocols to help you manage and control it easily. Utilizing the traditional WAN can help you to manage it, but when your business is growing, you need more advanced technology to control the data system, especially if you have business branches in different areas.

While we know the differences and the advantage of SD-WAN, here how it can give the benefit for your business:

1. Reduce the Budget

SD-WAN is totally different from traditional WAN that needs each MPLS. SD-WAN allows eliminating costly MPLS circuits. With the lower cost, your business can get advanced technology, higher-speed options for connectivity such as broadband, DSL, LTE.

2. Cloud-based Services

Traditional WAN routes back the traffic of data to data centers with a requirement to have constant filtering in place. SD-WAN architecture moves us closer to aloud services instead of toward local internet offloading.

3. Support High-Bandwidth Intensive Application

Traditional WAN has the problem of high bandwidth because of their architecture. Even though WAN has the same function as SD-WAN to provide interconnection systems, having the structure that provides high bandwidth can be more relevant for future business with more complexity. 

In the future, the agile principle can be more important for your business. The agile business needs agile technology and SD-WAN brings agility and speed of provisioning to the WAN.
