Stable buildings need solid foundations and enterprise-grade services are no different. If the underlying transport is too erratic no application service will look too pretty. Add in the limited number of routes and long distances between Internet regions and global, Internet-based enterprise services become predictably erratic.
Digital Transformation is perhaps the most widely used term in today’s business vocabulary and with good reason. It has the power to make or break organizations. Organizations of all sizes and in every sector have embarked upon some form of digital transformation (DX) initiative.
SD-WAN is a potential game-changer for wide area networking—on the same level as server virtualization, which transformed data centers over the last 10 years. SD-WAN combines the use of multiple active branch links, intelligent direction of traffic across those links, and centralized, policy-driven management of the WAN as a whole.
The Wide Area Network (WAN) is the backbone of the business. It ties together the remote locations, headquarters and data centers into an integrated network. Yet, the role of the WAN has evolved in recent years. Beyond physical locations, we now need to provide optimized and secure access to Cloud-based resources for a global and mobile workforce. The existing WAN optimization and security solutions, designed for physical locations and point-to-point architectures, are stretched to support this transformation.
SD-WAN at its core helps enterprises achieve dynamic alignment among business and IT strategy, application policy, and WAN configuration. In other words, it enables the WAN to provide the application experience (reliability, availability, performance), and application security demanded by business users, and the operational simplicity that IT and network admins yearn for in the current paradigm of rising IT complexity. We further explore these three key value drivers of SD-WAN adoption below:
Until recently, corporate networking has been a fairly stable component of enterprise IT. Its return to prominence goes hand-in-hand with changes in computing-infrastructure delivery.
SD-WAN analyst predictions around market growth have been smashed as trials have transformed into deployments. As businesses across sectors and geographies continue to digitize, SD-WAN offers enterprises a straight-forward evolution of the WAN. And it’s an evolution that is increasingly urgent:
