The advantages of the software-defined WAN concept are both real and compelling. The true novelty of SD-WAN is the incomparable versatility that can improve flexibility and agility in a scope of circumstances. If an organization is presently facing some bottlenecks in their day-to-day operations, this concept may offer viable solutions.

This can be countered by the use of the software-defined network, it will enable the company to deploy routers rapidly over all the offices, warehouses, and any other operational asset the company owns. Such aspects will enhance an increase in the speed of service delivery. Another problem that is curbed by the SD-WANs is the high WAN costs. Due to the cost of relying on Multi-protocol label switching (MPLS) proving to be too expensive for their relay needs, financially lacking establishments can support their transport needs at a much lower costs. Instead of relying on broadband substitutes that lack both in security and quality of service, they can utilize this technological tool to lower bandwidth costs while maintaining security and performance that even has the mettle of surpassing MPLS.

Another beneficial factor in using SD-WAN is the increase in data handling. Of late, corporate networks are tasked to relay a plethora of small files, video, voice and other files that prove not only large but also take up much more bandwidth in the process. A software-defined WAN allows business entities to expand to a network that can sustain these richer data formats while maintaining a bandwidth infrastructure that is relatively cheap to maintain.


Some readers may argue against the fact that software-defined WANs are critical to the growth of companies whose niche is dynamically demanding. Some areas of business such as software and gaming developers operate in worlds that are constantly changing due to factors like competition or consumer demand. Software-defined WANs can help companies efficiently administrate their network development attempts without breaking the bank.

Cloud-based WANs have also seen the improvement of service delivery, speeds, and affordability due to the advantages that emerged with them. Cloud computing is integral to both medium-sized companies and relatively larger companies; the operation consists of the concept of physical assets being virtualized and transferred to a cloud. In the event that an enterprise application requires a computer resource such as a virtual storage, the application goes to get the source from the cloud. This although practically sane involves a huge amount of data that is relocated between the enterprise and the cloud provider. This will result in a significantly negative impact on the proper functioning of the application. Also, the connectivity costs could become prohibitive if a more pricey connection is needed to hasten the delivery of the data. Cloud-based WAN optimization will provide the same and even better performance than the need to go through such an expensive network upgrade.

Firstly, using this technology, the cloud storage being accessed and the data being moved to and fro is highly compressible. The data, therefore, is compressed as it crosses the WAN and then uncompressed at the other side. This action can reduce the amount of traffic flowing drastically. Secondly, the speeds of the movement of the virtual workload are greatly improved along with booting a server from the cloud.

The first change sums to software-as-a-service approach to the network running, whereby management devices and machine configuration screens situated within a cloud service, are accessed through browsers and utilize web APIs to push changes to remote network equipment. This can be described as cloud-enabled networks and was a discovery made by wireless LAN vendors who strived to restructure the configuration and administration of thousands of dispersed access points. Furthermore, this concept is applied to branch office routers, cloud VPN gateways and, some security machinations.

Another positive aspect of view regarding the cloud-based WANs is a point that entails delivering private or individually administered networks over a public infrastructure. Though cloud services inherently rely on the internet, they are ostensibly not all public services. Also important to state is how it can positively influence scalability. This tech can easily allow an individual or a business enterprise to scale up or down their working and storage needs quickly to suit the situation. This allows for flexibility as needs change gradually.
