How to Ensure a Successful SD-WAN Implementation in a Few Steps

Software-defined wide-area networking (SD-WAN) is a computerized and programmed method of controlling commercial network connection and circuit costs. It translates software-defined networking (SDN) into a solution that enables businesses to quickly deploy a smart hybrid wide-area network (WAN).


Moreover, SD-WAN helps you efficiently and cost-effectively administer applications in the cloud as well as in other domains. Traffic is routed automatically and dynamically via the most efficient wide area network (WAN) channel given the present network circumstances, the quality-of-service (QoS) needs of the applications sending and receiving traffic, and the cost of the circuit.

Here are some important steps that every NetOps team should take to make sure an SD-WAN deployment goes well:

Identify Who Will Manage SD-WAN

After you’ve determined that SD WAN is the best choice for your organization and that it meets the recommendations of your procurement team, you’ll need to select whether your team or a managed service provider will design, purchase, install, and eventually manage your system.

When a business gets a service from a service provider, the provider works with the business to design, build, and manage the SD-WAN infrastructure at each site. Moreover, owing to an SD-WAN controller, IT is in charge of controlling day-to-day operations as well as software delivery.

Analyze Each Site as a Distinct IT Environment

Your branches can be connected to your wide area network (WAN) using broadband, satellite, the Internet, MPLS, or any other available technology. Before switching to SD-WAN, you should look into these circuits at each location to figure out how much they cost and how reliable they are.

Find out which apps are needed for daily operations at each site, where they are, and how your wide area network (WAN) connection affects those apps. The aim is to develop ways to save expenses while maintaining or even enhancing office performance requirements so that we can meet and maybe exceed those goals.

Assess Your Applications

Using SD-WAN is pointless if you cannot manage mission-critical business apps. Before implementing SD-WAN, it is critical to do a protocol and app audit. What effect does this have on your company’s bandwidth and routing? This step must be completed to build a custom SD-WAN system.

You should also start categorizing your programs as soon as feasible, bearing in mind the linkages that each program follows as well as the connections it makes at the end. Hence, to do application-based routing over all available connections, your new SD-WAN system will apply rules.

Retain Existing Infrastructure

A large majority of firms approach SD-WAN adoption with the wrong mindset.

IT management has the propensity to believe that adopting SD-WAN must be a rip-and-replace effort or exceedingly disruptive to install. We noticed that it was exactly the opposite of what was stated. If a firm’s SD-WAN provider permits pass-through installations, the company may continue to use its existing wide area network (WAN) infrastructure.

Perform Pilots and Testing

Pilot projects and staged rollouts, which are often used by clients with a lot of experience with SD-WAN, are thought to help businesses figure out and understand their networking needs better. This strategy also lets SD-WAN technology be set up quickly, efficiently, and in a well-organized way at several sites.

As such, organizations can detect and rectify any issues that may develop, making future deployments easier. Installations should also be performed during non-critical periods, such as when offices or stores are closed.

Priority Should Be Given to Security

When it comes to the requirement for rock-solid security, a traditional network that is tethered to the underlying hardware is just as important as a virtualized network. The SD-WAN is built around security, which could be a benefit instead of a problem. When you utilize SD-encryption WANs and firewall capabilities, the management of your network’s security becomes more centralized and standardized, resulting in a simpler network.

In general, the security flexibility provided by SD-WANs is usually greater than of other traditional solutions. SD-WANs allow you to “traffic-shape,” which enables you to define rules depending on the kind of traffic you have, increasing the network’s safety.

Final Takeaways

To sum up, you should carefully plan your SD-WAN project, make sure to speak to professionals in the field, and possibly even consider managed network services so that you are set up for success and can get the most out of your SD-WAN deployment by following the steps previously discussed in the article. This will allow you to get the most out of your SD-WAN deployment and maximize its potential benefits.
