Traditional WAN architectures are limited to enterprises, branch offices, and data centers. As enterprises adopt cloud application services in the form of SaaS/IaaS, the traffic of these globally diverse applications is exploding, and their WAN architecture faces enormous traffic challenges.
The shift in business models has given IT staff a lot to think about. Employee productivity is affected by SaaS application performance issues. At the same time, the use of dedicated and backup circuits is inefficient, making WAN costs so high. Day after day, IT personnel must find ways to connect users of all types of devices to a cloudy environment, and the challenge is even more daunting.
What are the advantages of SD-WAN?
• Simplify management. SD-WAN is a centralized WAN architecture delivered through the cloud that allows you to easily scale thousands of endpoints scattered across branches, campuses or the cloud. IT staff can use a single management interface to import automated jobs across zero-touch deployments around the world.
• Improve the user experience. WAN optimization provides optimal cloud application performance for users in any location from multiple clouds. In the case of unfavorable or slow down networking, the application sensor can maintain the transmission performance of business-critical applications through dynamic connection and secure networking through routing circuits. In addition, companies can use the more affordable and flexible bandwidth (including secure VPN connections) to offload the costly MPLS services to reduce operating costs.
