What is Nuage SD-WAN? – Definition, Features and Uses

What is Nuage SD-WAN? Networking in the enterprise can be an expensive proposition with traditional networking architecture relying on ITSPs, carriers, and vendor-neutral vendors. With the advent of cloud computing and software-defined networking, data has become the business commodity instead of a luxury access granted only to the highest echelon of corporate personnel and their trusted peers. With all this said, more companies have started exploring the benefits of a software-defined network which relies on efficient SD-WAN rather than the traditional networking. As such, some of these companies have found out that using a good networking service provider can be more costly than anticipated and to avoid this, they have decided to switch over to SD-WAN at a lower level.

Now, the question that arises is whether it is worth investing in SD-WAN for your company’s entire network, or just for some specific locations and application domains? The answer lies in defining how you would use the data centers and network to justify the additional cost. For example, an enterprise might want to connect its entire network to the public cloud, while others may only need to use private clouds for their scalability or disaster recovery purposes. Similarly, there are some third-party applications that may not need to be hosted in the public cloud but can still benefit from high-quality SD-WAN connectivity.

Now that we know what we want, the next question is what to do once you have your SD-WAN solution? There are a few different options available to a company when considering a switch to software-defined networking. The first option is to utilize the SaaS model where an entire corporate network is replaced with an online service. This is a less expensive way of going software-defined as you can sell your entire SD-WAN hardware and software license at the same time and continue to recoup your investment over the long run. Additionally, there are more control options available to your end customers including load balancing, availability, and upgrades to accommodate growth.

Another way to move forward and utilize your SD-WAN solutions in the cloud is to utilize the capabilities of software defined networks (SD-N). As the name implies, this concept allows for all the features of a traditional SD-WAN hardware solution to be delivered through software while taking advantage of lower cost equipment. This includes the ability to leverage low-cost equipment like Cisco hardware or switches to deliver guaranteed performance. However, this model assumes that all customers will use the same SaaS model and the same gateway device. The combination of Cisco equipment and SaaS portals provides an excellent solution for a company that requires fast, reliable connectivity to the data centers but doesn’t want to invest in the hardware and software that go with this solution.

The question of what is Nuage SD-WAN? can be answered with another question; “How will you define and measure your success with your SD-WAN solutions?” This requires a well thought out approach that takes into account your current needs, your future goals, and the latest trends in Ethernet connectivity and how they impact your business.

To make sure that you get the most value from your SD-WAN investments, it’s important that you do your homework on Ethernet technology and consider how each type of service compares to traditional architecture. You also need to understand the benefits of software-defined networking and what your alternatives are if you prefer to go the route of software-defined networking. Once you have determined that software-defined networking fits your needs, it’s important to make sure your network can handle the capacity of your expanding business. By taking some time to assess your current network and what you plan to do in the future you’ll be able to select the best network configuration for your company.
