Stitching together multiple WAN technologies to connect branch offices in a private network is not for the faint-of-heart.
It’s not too arduous for a handful of sites to research, purchase, and maintain the devices and equipment and addresses and applications and configurations and backup links. But hundreds of these? Thousands? Real businesses include locations of varied physical structures, larger offices, smaller offices, showroom booths, construction trailers, pop‐up retail mall kiosks, some permanent, some temporary, some stationary, some roaming.
Workers at every site expect predictable network access. And now your customers also do - and it might just be beneficial to your business to provide it. If only you could find a manageable way to do so.
Today a cloud-delivered SD-WAN helps you remove the complexity: the profusion of boxes and convoluted configurations. An SD-WAN allows you to orchestrate business, QoS and security policies, as well as application access, regardless of where the worker or the application is, or what physical devices or networks may connect them at the moment of access. Flexible and location-independent, the SD-WAN steers traffic directly between source and destination, mobile-worker or remote office, to SaaS server — allocating bandwidth and prioritizing traffic to provide the appropriate end-user experience.
The cloud took the applications out of the branch office; the SD-WAN takes the hairpinned traffic, and associated delays, out of the data center. An SD-WAN identifies application traffic, applies QoS policies and path selection to provide direct, reliable, high-performance access from any location to applications that reside in either your data center or the cloud.
With multiple branch office links—private, broadband, cellular, whatever is available and affordable—the SD-WAN aggregates disparate links into a single virtual conduit governed by single-point specifications for business, QoS and security policies. Simple and cost-effective, available links and bandwidth are automatically detected, continuously monitored and traffic is steered to optimize throughput, bandwidth allocation, application performance, application availability, and end-user experience.
Cloud-based applications, accessed by Internet-connected user devices, demand security applied flexibly and dynamically to decentralized traffic wherever it may flow, orchestrated from a single point. The SD-WAN encrypts traffic where needed, when needed, with dynamic VPN tunnels, and applies firewalling at the cloud entry-point to the virtual network.
The number of networking devices in the branch is steadily increasingly—many untethered and roaming. Sometimes the entire remote office moves. From this kinetic environment every worker expects instant access to delay-sensitive, business-critical applications. Remote retail site Guest WiFi is fast becoming a must-have, enabling in-store initiatives and interaction with consumer mobile devices.
