Software-defined WAN (SD-WAN): The new landscape of networking

More users.
 More apps.
 More devices.

An influx of data and devices is pushing the limits of traditional WAN architectures, making it nearly impossible for networks to keep up. IT is trying to increase bandwidth and improve connectivity, but they can’t do it alone. Enter Cisco SD-WAN.

With the power of software-defined networking on the WAN, businesses can improve performance, reduce costs, and enable robust security. It’s a cloud-scale, software-driven architecture that routes traffic around problems, ensures application performance, and adapts to changing conditions—all without direct IT intervention.

Most organizations experience about
 six unplanned outages per year.1

Harness the power of the cloud.

Today, your network has to work harder than ever to deliver the required user experiences over the cloud. With Cisco SD-WAN, you can enable applications in minutes, on any platform, with consistent, predictable performance. SD-WAN helps you optimize your wide area network, which means better experiences for customers and employees.

In a single overlay that extends to data center, cloud, and branch locations, Cisco SD-WAN optimizes software-as-a-service (SaaS) performance for Office 365, Salesforce, and other cloud-based apps. It also delivers seamless connectivity to the public cloud to simplify workflows for Amazon Web Services (AWS), Azure, and more—including application-aware policies that allow real-time policy enforcement for cloud and on-premises solutions. A recent survey showed that most organizations were able to bring unplanned outages down by 82%.¹

Network traffic
 is growing 30% year over year.2

Grow more, spend less.

Bandwidth is expensive enough as is, and network traffic shows no signs of slowing down. What if you could get simplified management and operations while lowering costs and increasing agility? Cisco SD-WAN offers faster, easier deployments and operations, as well as better performance. Now you can get more bandwidth for less cost.

Combine Multiprotocol Label Switching (MPLS) with low-cost broadband services using a hybrid WAN approach, and save time rolling out new services and branches. Centralized management and built-in automation simplify workflows to increase efficiencies even further.

90% of SD-WAN early adopters plan to use the cloud for enterprise apps next year.3

Deliver a unified security architecture for multicloud connectivity.

A lack of unified, end-to-end security from the branch to multiple clouds is increasing risks to organizations. Opening the enterprise to the cloud expands the attack surface of vulnerability points. Providing the right level of network access to the right people at the right points in the network becomes critical. Cisco SD-WAN provides a robust security architecture to connect users to applications with best-in-class security deployment models combining branch edge and cloud edge.

Achieve comprehensive threat protection and compliance for migration to multicloud architectures. Single cloud management of networking policies and security policies simplifies deployment and helps make protection more pervasive. Business-critical assets are isolated and protected at all times because threat defenses are embedded at important points of the network infrastructure, from branch to cloud.

WAN complexity is one of the top three concerns plaguing enterprise architects.3

Scale with simplicity.

Managing hundreds and thousands of branch locations has always been a major challenge with traditional WAN architectures—especially since they were previously managed on a per-device basis with separate networks on MPLS and broadband.
This complexity made consistent policy seem like a distant goal, made even more unattainable when a policy change needed to be rolled out across all sites. SD-WAN makes consistent policy not only possible but seamless.

It doesn't matter if you’re managing tens or thousands of locations; SD-WAN simplifies network management. With a single WAN fabric, all policies and configurations can be centrally managed, even across multicloud environments. The outcome is true simplicity at an enterprise scale.

Seamlessly integrate across systems.

APIs enable IT to seamlessly integrate its existing operations environment with Cisco SD-WAN while also allowing a high level of flexibility to deliver capabilities that might not be available within Cisco vManage. For example, enterprise IT service management (ITSM) tools can be used to automate trouble tickets if there are issues with the WAN, enabling the artificial intelligence and machine learning engines of the ecosystem to deliver the fullest experience without IT intervention. Network monitoring tools can be used to aggregate data from the WAN with data from the rest of the network to provide a more holistic view of the enterprise, making it easier to troubleshoot and pinpoint problems faster. Service providers can also use APIs to integrate with their operations and billing systems to monitor customer networks and usage while orchestrating changes across large numbers of nodes.

Deploy without speedbumps.

SD-WAN delivers rich benefits as far as costs, security, and simplicity. But the key to a successful SD-WAN transformation is to put the right focus on the initial setup and transition of the first 5 to 10 sites. And then to expand SD-WAN across the rest of the enterprise rapidly. This is where services from Cisco Customer Experience are able to deliver the biggest value. Drawing from the best practices of successful deployments from numerous enterprises, ranging from simple to complex, the Cisco Customer Experience team´s focus is to make the transformation smooth and avoid major hurdles. Categorizing the various sites, establishing templates, defining global policies, and enabling the right security architecture is a sure way to a smooth and successful deployment.
