Traditional network architectures were not built with cloud in mind.
As organisations have transformed the way they deliver workloads and embraced cloud services, this has often had a significant impact on performance, especially for those whose users are spread across multiple office locations.
Network operations teams have been looking for a better answer to the new demands placed on them by digital transformation. The answer has been the Software Defined Wide Area Network (SD-WAN).
SD-WAN offers them the ability to centrally control and optimise traffic across the WAN using the most efficient transport routes. This has allowed them to get rid of costly legacy equipment, and deliver the highest quality user experience across the applications and cloud services they use. Better still it can be delivered as a managed service.
Let’s look at some of the key benefits of SD-WAN in more detail:
Makes the complex simple
SD-WAN simplifies the network. Continuous monitoring means it chooses the most efficient route for your IT traffic, utilising broadband for non-critical business apps. Traffic is managed through a central single pane of glass not the hardware, so there is no need to send engineers to set policies in local branch offices.
Direct access to the cloud
SD-WAN augments or even replaces MPLS connections with broadband internet services to connect users to applications wherever they are. This improves cloud performance and can lower WAN costs by up to 90%.
SD-WAN helps stop unauthorised traffic from entering the branch by covering all your endpoints with end-to-end encryption. The segmenting of applications along different routes reduces the attack surface.
SD-WAN directs real-time services such as VOIP over the most efficient route. Reduced packet loss and latency ensures a high quality user experience at all times. It minimises network sprawl and delivers consistent performance.
