The traditional hub-and-spoke wide area network (WAN) architecture is no longer viable.
While this statement may seem premature, two major forces shaping the business world have led to this inescapable conclusion: cloud computing and mobility. The first introduces new and more complicated touchpoints for data across a spectrum of services that include infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). The second force encompasses new endpoints, devices, and data and applications being accessed from anywhere.
We live in a world of borderless computing on the far edge, the near edge, in the cloud, and in the data center. A traditional hub-and-spoke WAN with all the compute happening in the data center simply can’t accommodate this anywhere, anytime, any device reality.
