How SD-WAN Improves Business Agility

      Posted by Sydney Boman on Feb 23, 2017 11:10:00 AM


      Businesses today are constantly striving to become more agile in an effort to gain a competitive advantage. The key to becoming an agile business is to have an underlying agile IT infrastructure. Thus, businesses spend billions of dollars investing in technology to make IT more agile.

      As a result, virtualization has become the norm, and the level of agility is on the rise. With virtualization, investment in cloud-based solutions is on the rise; ZK Research predicts the investment in cloud computing will grow from $46 billion in 2014 to $116 billion in 2019. This means that more workloads will be moves to the cloud, affecting the traffic patters over the traditional wide area network (WAN).

      The brutal truth of the matter is that with the evolution of IT, the underlying network that our business run on has remained largely unchanged. The time has come, now, to evolve the traditional WAN so that agility can be a reality.

      Legacy Wide Area Network Challenges:

      The traditional "hub and spoke" network design has largely been inefficient in handling the influx of traffic from cloud services. Additionally, due to design issues, the network bandwidth is not utilized properly when accessing cloud-based content, creating a trombone effect where rapid traffic growth is inhibited. MPLS circuits have created a way around the trombone effect by increasing available bandwidth. However, the cost of this and other high bandwidth solutions is very high.

      SD-WAN as an Agility Solution:

      SD-WAN is giving network control back to businesses, allowing the network to become a more strategic resource. SD-WAN is composed of hybrid network architecture offers companies extreme cost savings over alternative solutions. Additionally, SD-WAN can optimize network connectivity for cloud computing, offering a secure and high-performance connection. This means that SD-WAN is lowering the complexity of running a network while simultaneously improving agility and efficiency.


      The path to greater business agility lies with implementing greater network agility. A company is only as strong as its weakest IT process, and for years WAN has been left stagnant as other processes thrive. Companies looking to achieve a competitive advantage can no longer ignore the importance of improving WAN. By moving to a software approach, businesses will realize greater network agility. SD-WAN allows businesses to accommodate heightened traffic from mobile applications, video and cloud computing, while limiting resources required to run and manage the network. What could this do for your business?
