The management of Wide Area Networking (WAN) which connects hundreds or even thousands of locations can be difficult to manage even in the simplest of situations. WAN demands are becoming more critical and complex as enterprises seize the benefits of the cloud, the need to simplify the deployment and management of these networks is growing rapidly.  As traffic increases, enterprises are searching for a more flexible, intelligent and cost-effective way to route traffic.  SD-WAN provides enterprises with increased network agility, quicker deployment time frames and cost reductions.

The market for SD-WAN products and services will grow impressively for the next several years, reaching $6 billion in 2020.

Traditional WAN

Inflexible & Slow

Since the data sources of traditional routers are often stored locally in datacenters with no direct cloud access, making changes can be difficult. It can be troublesome deploying and managing proprietary hardware.

Complex Infrastructure

Traditional WAN includes a multitude of single-function devices and appliances connecting via different WAN links. This causes extensive troubleshooting, multiple points of failure and complicates IT management.

Expensive

MPLS circuits come with limited bandwidth, limited availability and can be costly to deploy & manage. Upgrades can take months, limiting the productivity of your organization.

SD-WAN

Increased Business Agility

Implement large scale SD-WAN quickly. SD-WAN simplifies complex configurations without proprietary hardware. Easily insert network services, whether on the branch customer premise equipment (CPE), in the cloud, or in data centers.

Leverage Reduced Bandwidth Without Sacrificing Reliability

Leverage lower-cost broadband or mobile connections and deliver increased reliability with the option to backup connections in normal operations. So you use all the bandwidth that you’re paying for, while also ensuring seamless failovers.

Lower TCO

Cloud based management gives a pay-as-you-go model- so you only pay for what you use. In addition, reduce truck rolls with on-premise equipment maintenance, spend less time with the help desk, and gain cost savings with a BYOD (bring your own device) model.

Dramatically Reduce Bandwidth Costs &
Deploy 10x faster

SD-WAN allows for zero touch deployments; a traditional WAN setup may require sending multiple IT personnel to each branch and the turn up process can last weeks or even months. With TeligentIP, the deployment of SD-WAN can happen in a matter of a few days because the design and installation workflow is done in the cloud.

In Healthcare, MPLS backbones have previously been considered the standard for business application delivery but the bandwidth needed for these increasing critical applications is making MPLS an expensive proposition. Add in the cost of sending in IT personnel to each location with every update, change or new location and that’s when the costs catapult.

When healthcare businesses depend on applications to manage patients’ data, even a small hiccup can dramatically impact the clinic’s ability to provide care, which in turn impacts patient outcomes. Even more so, with the healthcare industry is relying on bandwidth intensive applications like VoIP and unified communications- lag, jitter and downtime become even more critical to monitor.

A cloud delivered SD-Wan solution with unified management and application performance optimization capabilities can provide easy, policy-based forwarding of application flows to different on premise systems and cloud services. This will help healthcare organizations, and many other organizations using WAN, improve their operations, increase application availability and reduce costs.

WAN TRENDS TO WATCH

#1

WE’RE ALL MOVING TO THE CLOUD

Worldwide spending on public cloud services will grow from $70 billion in 2015 to more than $141 billion in 2019

#2

COMPANIES NEED SD-WAN FOR HELP

The top 3 reasons for considering SD-WAN is the need for consistent security, price, and reduced complexity.

#3

By 2018 60% OF ENTERPRISE IT WORKLOADS WILL BE OFF-PREMISE IDC

Chief Analyst Frank Gens believes the industry is at the dawn of a Cloud 2.0 stage. “Even for those enterprises already familiar with the cloud, it will be a new challenge to get ready for these significant changes in what clouds are, and are able to do,” Gens says.

SD-WAN IS GROWING, AND ITS DOING IT QUICKLY IDC

report published in March 2016, shows A survey of enterprise communications professionals and found that 30% plan to migrate to SD-WAN within two years. IDC also expects SD-WAN sales to approach $600 million this year. By next year they will more than double to $1.4 billion, and almost double the year after to $2.6 billion by 2018
