It’s getting harder to define the boundaries of your enterprise nowadays. It used to be as simple as “inside and outside” the network and the firewall—but the distributed nature of today’s IT is rapidly changing the edge of your network. Your wide area network (WAN) needs to be able to easily expand and adapt to encompass not only branch offices—but also the resources and applications that are moving to the cloud. Can your network easily handle that? The sad answer is most can’t – because many networks have remained tied to the physical metaphor of perimeters, walls, and equipment. You need to be thinking about the edges and expansion of your WAN—not necessarily the physicality of it.
Don’t misunderstand, there’s no denying the physicality of the network. After all, it’s put together with cables, wireless routers, and other networking equipment inside your buildings. The fact is, the demand for increased bandwidth, optimized connectivity for the cloud, and improved security postures to tackle next generation threats can be difficult to meet with traditional WAN architectures. Add to this, the increasing use of cloud-based applications and the emergence of the Internet of Things, and your WAN may be inadequate for the future. Even now, existing wide area networks across businesses and organizations of all sizes and across all industries are struggling to cope.
