SD-WAN (software-defined WAN) is a wide area network deployment method. Using virtualization and application, SD-WAN controls and establishes WAN (wide area network) and devices across branch offices.

Cloud adoption places intense new demands on enterprise networks. Performance, security and scalable bandwidth are vital to running mission-critical applications hosted in the cloud. Network transformation is a priority on the CIO agenda to support a cloud strategy and a more distributed enterprise IT environment. The traditional wide area network (WAN) was not designed for cloud-based application performance, which is why SD-WAN now commands the attention of many CIOs. Industry research firm IDC estimates that 82 percent of enterprises will have implemented SD-WAN within the next 18 months, increasing from 38 percent in early 2017.
Below are four use cases highlighting the business benefits of SD-WAN:
Reduced costs. Enterprises need direct and cost-effective network access to applications hosted in the cloud. SD-WAN can route non-mission-critical application flows over less expensive broadband internet directly to the cloud by leveraging application-aware intelligent routing. This results in reduced WAN operating costs while ensuring appropriate security, reliability and performance for all applications.
Improved IT agility and simplicity. Enterprises seek reduced complexity, faster service provisioning and greater flexibility. SD-WAN’s centralized provisioning of WAN connectivity at a site level, aligned to business policies, reduce the complexity of managing network equipment at the branch level and relieves the burden on local IT resources.
Strengthened data security for all applications, especially those hosted in the cloud. Traditional WAN connectivity options guarantee the reliability and security of data traffic, while broadband internet or LTE may not offer the same assurances. SD-WAN solutions leverage integrated security features such as network address translation, IPSec tunnels and firewalls to enhance data security for all applications connecting to the cloud.
Enhanced customer engagement. Improving customer experience ranks high on the list of priorities for many CIOs. SD-WAN enables improvements in user experience by ensuring applications are available and performing well.
GTT’s managed SD-WAN service utilizes the company’s Tier 1 global IP backbone, ranked among the largest in the industry, securely connecting client locations to any destination on the internet and to any application in the cloud. GTT offers the widest range of access options with bundled network security, making it simple and cost-effective to add network locations and bandwidth as needed. Clients benefit from a flexible networking platform and a company culture that strives to say yes.

As the market leader in mid-market and enterprise SD-WAN services, I think this question is posed on nearly every customer or partner interaction that we have. I would say that MPLS isn’t dead by any means, but it’s stronghold as the standard for the WAN (along with its $40 Billion annual market share) is certainly rapidly eroding.
Two fundamental shifts have occurred in the past decade which have changed the way applications are deployed and managed: cloud computing and the availability of low-cost, high performance Internet connections. These shifts are at odds with the way legacy MPLS-based WANs have been deployed. What was once seen as a form of secure connectivity from remote offices worldwide to a small set of corporate data centers is now creating debilitating limitations when attempting to integrate cloud computing or take advantage of commodity Internet connections for remote office high availability or performance.
With a legacy network architecture, application traffic is sent from the remote office to servers in the data center over MPLS private WAN connections. While these networks set the standard for security, they are also an order of magnitude more expensive than standard Internet broadband or cellular connections. Further, cloud-hosted and software-as-a-service (SaaS) applications do not reside in the data center, and often, a direct path to the Internet from the remote office would provide better performance and substantially lower cost.
Information Technology (I/T) organizations have become accustomed to managing networks by configuring a series of fragmented, fragile, and sometimes non-interoperable features on low-level networking devices. Businesses today are demanding that the inherent complexity be reduced or eliminated in favor of companywide policies that map to intent rather than elements that only seasoned veterans understand. Policies today map to IP addresses, ports, queues, and interfaces, where they should map to applications, networks, sites, and profiles for performance, compliance, and security.
Networking must change to accommodate the new normal of cloud applications.
CloudGenix Software-Defined WAN (SD-WAN) is the industry’s most complete solution for customers that want to build hybrid networks consisting of MPLS private WANs and commodity Internet connections for cloud application adoption, remote office high availability, application performance, and end-to-end visibility. Powered by CloudGenix Instant-On Networks (ION) devices deployed in locations where visibility and control are desired, CloudGenix SD-WAN allows you to create policies based on business intent rather than a series of fragmented networking features, enables dynamic path selection using the highest performing network, and provides visibility into performance and availability for applications and networks.
Is SD-WAN right for your network. No obligation SD-WAN Assessment.
A secure application fabric, AppFabric, is established amongst all ION devices, creating a virtual private network (VPN) over every WAN link. Policies are defined that are aligned with your business intent that specify performance, compliance, and security rules for your applications and sites. ION devices will automatically choose the best WAN path for your applications based on business policy and real-time analysis of the application performance metrics and WAN links.
Our industry is in the middle of a paradigm shift because of the cloud and yesterday’s WAN is obsolete. I/T has a new set of demands from the business and the ask is high:
