SD-WAN is a tech acronym for software-defined wide-area network, don’t confuse it with cloud network. SD-WAN network employs an automatic programmed approach in order to efficiently manage an enterprise’s network connectivity and reduce its circuit costs. The function of a SD-WAN is to turn the software defined networking (SDN) into an application. This approach works well for the business enterprises and organizations which use a lot of applications and want to swiftly incorporate the smart and hybrid WAN. The Hybrid WAN’s architecture is comprised of a business-grade IP VPN, wireless services and a broadband connection.
The traffic generated for the enterprise network is automatically routed across to the specified WAN path that the network programming judges as the most appropriate one depending on the state of the network at that time. There are other factors that would also determine the traffic routing. These include the level of security of each network path and the specified quality-of-service requirements stipulated by the application traffic on the network, the cost of the circuit is the final determinant of routing on a WAN path. The enterprise managers have the full control over the routing policies.
The SD-WAN technology comes with an attractive feature which makes it preferable to business owners. For instance;
• All the devices connected to the network can “load-share” across the network.
• SD-WAN is programmed to automatically switch to and provide premium network services.
• It is possible to switch to other types of connections like WAN optimization and VPN
• It activates firewalls and controls the delivery of applications.
• It supports zero-touch provisioning
• The network is compatible with multiple kinds of connections.
The innovation of the cloud technology disrupted the way businesses and ordinary consumers used their network. The popularity and growth of the cloud created a market that needed to be supplied with the WAN technology. The demand has been naturally grabbed by a host of start-up which have cropped up to address the urgent gap in the supply of this new technology. Cloud services are now easily provided using a software only model.
Unlike the public internet, using the cloud comes with enviable perks that are responsible for an increase in the number of people seeking this service. Data enjoys more security in the cloud. WAN on the other hand are optimized and internet speeds are higher.
WAN deployed over the cloud interface is called the software-defined WAN (SD-WAN). By design, it makes it easier to deploy the WAN services and even easier to use them in either corporate settings or much smaller enterprises. Managing the WAN services on the cloud is easy as it can be done from a remote office. This service continues to be one of the leading trends in the business fields where networking is key.
Broadband services are now being provisioned with the SD-WAN and is now easier and cheaper to deploy than before. This created such a spike in the demand for broadband services especially in homes such that most new homes nowadays come pre-installed with the service. People who want to add it to their houses can also have it provisioned within a short time at a fee by internet service providers. It is also easier to manage this service as it can be done over the internet eliminating the need to be physically present at the remote location of the devices.
The cloud technology has drastically reduced the time that is needed to install applications. App installation used to be a fairly difficult process before the cloud was invented. There had to be a server first before any attempt was made at installation followed by a network installation to support the application. The network had to be fully functional for the installation to commence. The advent of the cloud has eliminated this long and difficult chain and consolidated everything to be executed remotely using a computer.
