Organizations trying to manage wide-area networks (WANs) face no shortage of challenges. Business growth and the use of cloud-based computing and storage for applications are increasing demands on the network as well as the costs of managing WANs. A new white paper from Nuage Networks looks at how software-defined wide-area networks (SD-WANs) are changing the way networks are structured to make them more suitable for the cloud-based ecosystem of today.
As organizations grow their number of users and locations, WANs become more complex and difficult to manage. IT needs networks that are more dynamic and flexible, particularly for large enterprises that operate dozens of branch offices. SD-WANs help simplify the management and operation of today’s increasingly complicated WANs. The white paper highlights the results of a new survey by IDG Research and Nuage Networks that looks at changing enterprise attitudes toward WANs, the problems they expect their WANs to be able to handle, and experiences of SD-WAN early adopters.
More than half of respondents cited two main challenges associated with the WAN: 1) increased complexity and number of network appliances to maintain; and 2) time-consuming manual processes for moves, adds, and changes. The survey found that most respondents are not very confident that their existing WAN architecture, rollout processes, and management tools can support future business goals such as making the network more responsive and optimizing the network to support new technologies.
SD-WANs are more dynamic, and therefore more suitable, for today’s IT environment, where cloud-based applications are fluid and unpredictable in terms of how they are used and the source location. Based on an overlay model that uses any IP network to provide connectivity between sites, SD-WANs offer maximum flexibility and support for multiple access and last-mile technologies to deliver a responsive network to branch locations.
This is significantly different from traditional, static WANs, which are slow to adapt and change and cannot support bursty cloud applications whose traffic demands vary heavily over time. With SD-WANs, the intelligence behind network functions such as routing and switching, as well as the movement of traffic, is placed in software rather than hardware platforms. The survey found that any organization that has already implemented SD-WAN says it has simplified management and operation of the overall network. Early SD-WAN adopters also say the technology:
- Enables seamless linking of enterprise locations, regardless of size or geography
- Provides centralized, policy-driven management across locations
