What is SD-WAN and benefits of SD-WAN


From WAN to SD-WAN

Traditional WANs are based on multiple devices in the branch office with siloed management and disparate links connecting them. With expensive bandwidth, unpredictable application performance, data-center dependency, and complex infrastructure, the traditional WAN is broken.

Evolving the WAN must be a top priority for every IT and business leader because organizations can only be as agile as their least agile IT component—which, today, is the WAN. How can your business reach the level of agility required to compete in today’s digital world with an outdated infrastructure?

The answer: Software-Defined Wide Area Network

SD-WAN is a transformational approach to simplifying branch office networking using a virtual WAN architecture, allowing enterprises to leverage any combination of transport services—including MPLS (multi-protocol label switching), LTE and broadband—to securely connect users to applications. Using centralized control functions that intelligently direct traffic across the WAN, SD-WANs increase performance, resulting in enhanced user experiences, increased business productivity, and reduced IT costs.

How Will SD-WAN Benefit You?

SD-WAN benefits businesses by eliminating the need for expensive routing hardware and simplifying the process of provisioning network connectivity and cloud services in real-time. By allowing network administrators to use bandwidth more efficiently, SD-WAN lowers operational costs (1/3 the cost of solely using MPLS) and improves the performance of critical applications without sacrificing data privacy or security. Plus, since it’s software, configuration onto your current infrastructure is quick and easy.

While there are countless technological benefits, its potential impact extends beyond IT, network administrators. 

Here is a list of our top three SD-WAN benefits:

1. Enhanced Security

SD-WAN presents an advantage for data encryption and network segmentation. With its greater visibility into network performance and its tools to encrypt WAN traffic in motion, IT administrators can detect risks in real-time.

2. Simplified Management

As a centralized, cloud-delivered WAN architecture, SD-WAN is easy to scale across thousands of endpoints, whether they are in the branch, campus, or cloud. IT can automate zero-touch deployment globally, using a single management interface.

3. Increased Flexibility

This easy-to-implement technology can be overlaid on existing WAN technologies to achieve control, management, and automation. The benefits of real-time performance management and features to personalize network configurations allow you to provision new networks, adopt cloud services, or accommodate remote workers in real-time.

When Should You Make the Switch to SD-WAN?

The time is now. In today’s cloud-dominated user environment, WAN can no longer deliver reliable application performance, which is essential to your IT infrastructure design. Traditional MPLS networks can’t keep up with the volume of Internet-based cloud traffic, the diversity of routing locations, and the level of application performance across both MPLS and Internet-bearing services. 

With industry demands to improve user experience and enhance application performance only increasing, it is the ease with which SD-WAN technology can be used—from agility and rapid change to multi-linked failover and application prioritization—that make this switch an easy decision.
