A WAN (Wide Area Network) its traditional function was to connect users of the branch office or campus with the applications hosted on the servers of the data center. But this doesn’t work in a cloud-centric world. Thus arises, SD-WAN for its acronym in English Software-defined Wide Area Network which addresses the current CHALLENGES of IT. This new approach to network connectivity can reduce operational costs and improve resource usage for multi-site deployments. Network administrators can use bandwidth more efficiently and can help ensure high levels of performance for critical applications without sacrificing security or data privacy.
Why is it important
Times have changed and companies use the cloud and subscribe to software as a service (SaaS). While users traditionally reconnected to the corporate data center to access business applications, they are now better served by accessing many of those same applications in the cloud. SD-WAN provides WAN simplification, lower costs, bandwidth efficiency, and continuous cloud access with significant application performance, especially for critical applications, without sacrificing security and data privacy. Improved application performance improves business productivity, customer satisfaction, and ultimately profitability. Constant security reduces business risk.
