Software Defined WAN
Software Defined WAN (SD-WAN) is a new, smarter and more efficient way to manage and optimize a wide area network. SD-WAN was created to overcome the high bandwidth costs and rigidity of MPLS services. It does that by incorporating internet transports (such as DSL, Fiber and 4G) into the WAN and forming a virtual overlay across all transports.
SD-WAN as a Service
Secure, global SD-WAN, delivered as a service, provides the core benefits of SD-WAN while enabling secure direct internet access, SLA-backed connectivity, and seamless extension of the WAN to cloud data centers and mobile users.
An SD-WAN simplifies branch operations and efficiently connects your branches to the internet, which makes establishing local breakouts easy. But those connections still need to be secured. As a matter of fact, SD-WAN needs to be as secure as MPLS to be a viable extension to or replacement for your MPLS based WAN.
How can you get visibility into and control over mobile access for cloud applications such as Microsoft Office 365 or Salesforce? Cloud applications represent unique WAN challenges due to the need to provide globally optimized access to a single regional instance.
Digital transformation forces enterprises to rapidly adopt new and innovative applications and to implement cloud based services, such as O365, AWS, Azure and Force.com. This causes an immediate challenge for traditional WAN technologies and requires a radical change of the corporate WAN.
