Traditional wide area networks (WANs) bring numerous challenges to the enterprise, ranging from increasing cost, performance issues and flexibility challenges. And with the onset of the cloud, today's IT teams are searching for solutions that meet the data accessibility demands from inside the organization to the edges of the earth. Specific issues traditional WANs bring are: ▪ Expensive Bandwidth: Limited bandwidth of expensive private/MPLS circuits often inhibits rollout and impacts application performance. ▪ Inconsistent Application Performance: Application traffic over the Internet lacks service level agreements (SLAs) for predictable performance. When application QoS needs updating, changes must be made across the branch locations and the data center. ▪ Data Center Dependent: With traditional hub-and-spoke network design, traffic is routed to a core data center which can create performance issues. ▪ Infrastructure Complexity: With the sprawl of disparate devices and WAN connections, complexity grows. ▪ Lengthy Provisioning Cycles: For any new sites requiring circuit delivery and equipment provisioning, traditional WAN sites can take months to turn up. ▪ Inadequate Redundancy and Resiliency: The high cost of MPLS services often makes redundant local loop connections impractical and not always useful, meaning that downtime and intermittent connectivity problems arise. To address some of the traditional WAN challenges, enterprises are adopting a new approach for their distributed networks - software-defined WAN (SD-WAN). SD-WAN offers better performance, agility, operational flexibility and potentially huge cost savings. But there are things to consider when choosing to move to a SD-WAN solution. Introduction "The most significant driver of SD-WAN growth over the next five years will be digital transformation (DX) in which enterprises deploy 3rd Platform technologies, including cloud, big data and analytics, mobility, and social business, to unlock new sources of innovation and creativity that enhance customer experiences and improve financial performance."
