As the years have gone by, IT has discovered that systems like SaaS and IaaS can hinder user experience and be clunky at times.
Further, opening the enterprise to the Internet and the cloud exposes major threat and compliance issues.
It is extremely challenging to protect the critical assets of an enterprise when applications are accessed by a diverse workforce, including employees, partners, contractors, vendors, and guests.
Enabling broadband on the Wide Area Network, or WAN, makes the security requirements more acute, creating challenges for IT in balancing user experience, security, and complexity.
What is SD-Wan?
As the name states, software-defined wide-area networks use software to control the connectivity, management and services between data centers and remote branches or cloud instances.
Like its elder technology sibling, software-defined networking, SD-WAN decouples the control plane from the data plane.
WANs use links such as multiprotocol label switching (MPLS), wireless, broadband, virtual private networks (VPNs) and the internet to give users in remote offices access to corporate applications, services and resources, allowing them to work regardless of location.
SD-WAN monitors the performance of WAN connections and manages traffic in an effort to maintain high speeds and optimize connectivity.
SD-WAN’s driving principle is to simplify the way big companies turn up new links to …
