COMPARISON BETWEEN SD-WANS AND CLOUD WANS

The most notable similarity between software-defined WANs and Cloud-based WANs is that they are all advancements and improvements of the initial wide area network. They both support applications that access data centers via traffic that comes in the form of mobile hardware components and cloud respectively. The traffic patterns created by the emergence of cloud and mobile computing has positively affected and improved service delivery, reduced costs, and enabled higher performance in various enterprises. Also a similarity worthy of mention is the fact that they are both extensions of the revolutionary concept of Software-defined networking. Another characteristic that shows how similar the two can be is the fact that they share several benefits. Also, we can state that the two technologies are regarded more as optimization tools for any existing WAN network. Optimization can be described as an act, process or method of making a system as fully perfect, functional or effective as possible. This is clearly viable since they result in higher performance and speeds of connectivity.
The only viable distinguishable feature regarding these techs can be assumed to dwell majorly around their functionality. The history of the WAN optimization market shows that focus has mainly been made on the optimizing performance of application traffic flows from a single link. However, Software-defined WAN, or SD-WAN, is all about virtualizing a range of connections to MPLS and the Internet, and seeking a way to balance traffic along these parameters.6060293142_bc7144a90e_b

The advent of the cloud services saw companies initially forget the fundamentals of IT. In the haste to embrace cloud services, they totally ignored network management, change control and issues pertaining capacity management. When many businesses diverted their effort to building their cloud platform, critical servers and data were now hosted on the cloud. With this came a significant increase in network traffic. With users accessing data and computing resources from both remote locations and corporate command posts, the network thus in essence became cloud-based. For businesses to maximize the efficiency of their operations they embraced the Cloud based WAN optimization tools. This majorly aimed to streamline the growing network needs of an organization that owns or manages servers and databases within the cloud.

The topic of Software Defined WANs and Cloud WANs has attracted a great deal of attention from service providers, enterprises, and key industry associations. With today’s enthusiastic reception of the technology, it is only logical to assume that the true picture of what it can do is yet to emerge. The basic concept of the SD-WAN optimization tool is that it centrally places intelligence of a WAN system. This fundamental point of view results in the increase of flexibility of network utilization, it also aims to keep the complexity of use as minimal as practicality can allow. This makes it easy to operate and maintain. It also introduces the abstraction of lower network infrastructure functionality, which is well suited for the efficient development of new applications.

Projections show that companies will invest heavily in internet infrastructure. The near future will also see the integration of hybrid infrastructure aimed at delivering the highest possible levels of security, performance, control, and cost efficiency. This will possibly see not only traders and scientists utilize this, but also industries will have a stake in it.
No matter from what perspective you choose to look it from, Cloud WAN and Software-defined WAN have come with a multitude of positives and still has plenty of room for development and opening up new solutions for IT companies in the future.
