At this point in the market adoption of Software Defined Wide Area Networking, SD-WAN vendors have developed several distinct technical approaches to improving network performance. Researchers at Gartner predict that by the end of 2019, 30% of enterprises will use SD-WAN products in all their branches, up from less than 1% today.
Because SD-WAN is a broad term that is still being defined by the designers and the consumers of this emerging technology, we wanted to provide an overview of the different approaches currently being offered, all with their own unique attributes, and point out pros and cons of each.
The SD-WAN solutions being offered today give end users, network administrators and Managed Service Providers (MSPs) the ability to adjust, optimize, automate and test their WAN connections through software controls. SD-WAN uses tools like encryption, Quality of Service (QoS), traffic shaping and alerts to make the most of the WAN connections. In addition to these core features, some solutions may also include functionality like firewalls, voice controllers and traffic optimization to get closer to a converged solution set.
The right SD-WAN solution makes your WAN work better, makes management easier, can save you the expense of downtime from unplanned carrier outages and the hassle of quality of service issues like jitter and latency. That said, the right solution needs to be chosen, deployed correctly and fully supported by a strong SD-WAN vendor to fully realize these benefits. The information in our Comparison of SD-WAN Solutions technology brief will help you identify the best solution for your business.
The three main solutions being offered by SD-WAN vendors are: virtual, cloud based and premise based.
Virtual Solutions.These solutions are targeted for large enterprises that have virtualized many of their network functions, considered part of the broader Software Defined Networking (SDN) or Network Functions Virtualization (NFV) adoption.
Cloud-Based Solutions. A hybrid solution that implements an edge hardware appliance in collaboration with a cloud based virtual appliance. These solutions function by routing the remote site, or edge, traffic through various WAN connections to a central cloud instance. The cloud instance is where the management software implements the features of SD-WAN.
Premise-Based Solutions. Solutions that leverage dedicated hardware appliances at the edge, data center, corporate headquarters and cloud to provide a scalable end-to-end solution. All traffic management features are located on the appliance with policies and configurations being managed through a web application.
In “COMPARISON OF SD-WAN SOLUTIONS” you will learn the differences between virtual, cloud-based and premise-based SD-WAN offerings, along with strengths and weaknesses of each. Based on the types of network traffic you have and your business priorities, you will understand how the various approaches could serve your organization. The document includes a decision matrix to help network professionals conducting research on SD-WAN vendors.
