SD-WAN – What you need to know (Including Benefits)

What is a SD-WAN

A SD-WAN connect users to their devices, from any device from any location at any time, no matter where their apps are stored.

Whereas WAN was hosted in an enterprise data-centre, however through the growth of cloud services such as AWS, Google Cloud, DropBox, Salesforce and others it added time delay, reduced quality whilst also using lease line bandwidth availability which increases spend and reduces efficiency.

The breakdown of a SD-WAN solution.

With the increased use of the aforementioned cloud based solutions it makes more sense to use the internet to access apps which are hosted there. This drove a more intelligent software defined solution. A SD-WAN does not route traffic on addresses but rather uses technology to divert traffic based on the business requirements for the specific applications. The control function has been centralised, this can then be used across multiple SD-WANs globally. There is no limit to this and as many SD-WANs can be combined for complete company wide security protection as well as more consistent, predictable application performance. Because this is done through software, the process of adding new devices, and updating procedures is quick and easy.

Benefits of SD-WAN

App Compatibility – on average 70% of apps are hosted on the cloud. Using a SD-WAN gives greater optimisation and security for the majority of your work.

Enhanced Agility – you can run traffic through multiple bandwidths for example 4G, MPLS, and Broadband. This means that the optimised service is always provided as multiple bands can be used at once and the best service can always be achieved.

Reduces IT Technician Requirements – if one of the bandwidths go down, traffic can be immediately re-routed through one of the others without performance being affected. Maintaining business standard and performance but also reducing the requirement for IT technicians to fix issues.

Increased Speed –  by using the internet for bandwidth this gives you better performance than traditional means.

Quicker Onboarding Process – leverage internet services new location can be brought online much quicker by utilising the remote sharing of information and not relying on physically being in the location.

Zero Touch Provisioning – this means that a new location can be automated through to be brough online without mistake rapidly, and through utilising broadband this process can occur in a few days instead of the traditional weeks.

Enhanced Security –  end to end segmentation breaks down bandwidth to fully assess traffic to ensure that you will not be put at risk. Security delivered in the cloud is easier to keep up to date and protect against the most current threats.

Lowers WAN Cost – when SD-WAN was first introduced the lower cost broadband, was the greatest asset. However, whilst this is still the case, many CISOs see greater benefits in the productivity and security offered by a SD-WAN, which combined with the opex costs being reduced by 40% brings a great amount of efficiency for their company.
