Software-defined wide area network as a service changes the game
Organizations must grow, expand and scale up to match the rising demand of the new age consumers. With the rapid proliferation of mobile devices and social collaboration tools, employees have their own demands, too. To meet these expectations, more and more organizations are moving to the cloud.
However, the cloud journey has its own challenges and constraints due to legacy networks. The role of a company-wide network is changing as IT operations continue to centralize, while business operations and employees decentralize.
The traditional wide area network (WAN) model simply isn’t up to the task, due to management complexity, extensive deployment timelines and lower agility of the monolithic MPLS-based connectivity. Throw in added concerns around security, cost savings and policy enforcement, and it’s clear that network infrastructure transformation is a necessity.
The turn toward SD-WAN
To meet these challenges, the software-defined wide area network (SD-WAN) model brings significant advancements in enterprise connectivity and management. In an SD-WAN architecture, companies can harness virtualization and benefit from lower costs, improved user experience, reduced risk, agility and flexibility. Increased cloud adoption is further fueling the interest in SD-WAN.
Enterprises are looking for a trusted business advisor that can provide SD-WAN as a service. This model is also referred to as managed SD-WAN, in which an enterprise typically pays the service provider a fee to install, deliver and manage their WAN. Enterprises expect a carrier- and OEM-agnostic solution that offers orchestration and automation with monitoring and maintenance capabilities, all under a single pane of glass.
This transition requires thoughtful strategy and design to prepare an organization’s infrastructure road map, coupled with a well laid-out implementation and management methodology. IBM’s Network as a Service solution helps meet these new requirements, providing scalability across multiple locations as needed by a true global network at optimized costs.
