Software Defined Networking (SDN): Growing at a Blistering Rate of 90 Percent Annually

By Dick Weisinger

The Software Defined Network (SDN) market will grow from just $960 million in 2014 to $8 billion by 2018, at an annual growth rate of 90 percent, predicts IDC.  That’s an incredible rate of growth.

Leading vendors in this market include Cisco Systems (CSCO) and VMware (VMW).  Others also in the market include Big Switch, Brocade (BRCD), Dell, Extreme Networks (EXTR), Flextronics, Hewlett-Packard (HPQ), Huawei, Juniper Networks (JNPR), and Oracle (ORCL).

Factors that are driving the growth in the SDN market include:

  • Increasing adoption of cloud applications and services by businesses
  • Increased interest in the software-defined datacenter and the converging of computation, storage and networking
  • Increased demand for networks to be more flexible and to be able to support rapidly changing technologies like mobility, big data, and the Internet of Things (IoT)

Rohit Mehra, Vice President, Network Infrastructure at IDC, said that “SDN is taking center stage among innovative approaches to some of the networking challenges brought about by the rise of the 3rd Platform, particularly virtualization and cloud computing.  With SDN’s growing traction in the datacenter for cloud deployments, enterprise IT is beginning to see the value in potentially extending SDN to the WAN and into the campus to meet the demand for more agile approaches to network architecture, provisioning, and operations.”
