Software Defined WANs and Cloud WANs

The demand to cut back on labor put into managing services provided over Wide Area Networks (WANs) by business owners and various companies is increasing everyday. There is a need to reduce costs involved in managing data and networking gear over Wide Area Networks (WAN) and this lead to the emerging of new forms of technology such Cloud WANs and Software Defined WANs that have become accessible and adaptable due to the development of cloud computing technology. Cloud computing defines to the combination of various types of WANs on a virtual platform. Hybrid wan connects a geographically dispersed wide area network (WAN) by sending traffic over two or more connection types.

What is Software Defined WANs and Cloud WANs

Before you understand about the technologies, we have to first understand the term Wide Area Network (WAN). WAN in simple terms is a network that comprises of two or more Local-Area Networks (LANs) and has an extensive geographical coverage through telecommunication circuits.

Software-defined WAN (SD-WAN) is a way to deliver the Wide Area Network services uses a form of software defined networking to define the most appropriate channels to use in the transfer and sharing of WAN services including traffic to distant isolated places. Cloud WAN technology virtuliazes functions entailed in the distribution of Wide Area Network (WAN) which means moving it to cloud.

The shift in the technological field means that companies and businesses are now able to invest largely into the option of shifting to SD-WAN and Cloud WAN optimization services. The company’s rate of production and positive customer feedback depends on how well your systems are networked within the networked circuit.

According to the Rayno report, a study conducted in 2015, the opportunity to have Cloud WAN services available has been estimated to be about $7.5B by the year 2020. One common dominant feature of applications is that as time advances they change and get modified in several ways requiring an access to different services. SD-WAN and Cloud WAN services over this exact flexibility that is an essential for business owners and other companies. Hitherto, over $360 million has been invested as capital in several of Cloud WAN startups of different types.

Through SD-WAN and Cloud WAN moves the process of monitoring traffic and managing the flow of data from physical hardware devices that are often too expensive and cumbersome to connect. The entire process shifts and becomes available on an application which ensures convenience and saves on the cost or expenses met. This form of technology makes WAN functions like branch-office routers, Virtual Private Networks (VPNs), WAN Optimization, and Application Delivery Controller (ADC) technology be virtualized and stored in the cloud.

Maintenance of the Software Defined WANs and Cloud WANs has a number of areas that create positive feedback from users such as improved management procedure, reduced hardware costs and saves on energy and space. Constant updating of these networks is required and therefore you should ensure that there is enough bandwidth to match the demand that exists within the network for the services offered in the entire Wide Area Network.

Cloud Technology

Advancement in the technological field especially with cloud computing has led to a consumer model which has increased the number of startups that make use of services on the Wide Area Networks provided and stored virtually in the cloud with a software only version. Migrating into the clouds involves functions such as: business-class Internet, security, WAN optimization and application policy control. Services offered through wide area networks are now easy to access, manage and use.

Software Defined WANs and Cloud WANs enhance the performance of networks and enable various additional functionalities. Businesses or organizations that require private line WAN connections and other included protocols such as MPLS often have to dig deep in their pockets and spend a higher price for the services which involve the use and managing of proprietary hardware. SD-WANs and Cloud WANs eliminate this consumer experience as much of the functions have been virtualized and placed in a cloud with a networking box or branch-office router. The process of setting up a Wide Area Network for your business or organization branch has become both cost effective and time saving as setting up takes only a couple of minutes.

Before cloud technologies rolled in, organizations had to instruct the IT personnel to install both a server and network so as to enable an application installation and manage it in person unlike now everything is available for purchase by anyone to access without complications just by the click of a button. You can link up several from hundreds to thousands of offices across the world through cloud and Software Defined WANs without the need to configure and reinstall the proprietary hardware. This is made possible by setting up the router and VPN in the cloud.
