A software-defined wide area network (SD-WAN) can help your business seamlessly improve productivity, accelerate your initiatives, and lower on-site WAN costs through its connectivity with the cloud. Office applications (like Google Suite, Microsoft 360, and many others) now mainly run in the cloud, hence the need for a WAN that’s suitable for cloud-native apps and can be implemented at scale to different sites or branches. This is where an SD-WAN comes in.
