Companies are adopting Software Defined Networking (SDN) as it has better flexibility and scalability than traditional networking.
FREMONT, CA: Modern technologies are stepping towards virtualization. In the past few years, industries have also systematically moved away from Hardware and invested in technology's software-centric approach. The primary reason the companies are switching is the internet and the abilities it has added to the traditional enterprise. The enterprises are attracted to the scalability, flexibility, and agility tendencies of the software-based solutions as it becomes easy for them to adapt and adopt.

In the industries, software of technologies has entered at every level. For example, the storage infrastructure has witnessed the Data Centre's transformation into the Cloud, Multi-Cloud, or Hybrid Cloud setting. Furthermore, various technologies like the Internet of Things and Edge Computing is diminishing the lines among Software and Hardware.
In the same way, networking architecture does don't follow the same traditional rule due to the Digital Transformation. The conventional network architecture was a complicated structure of various physical switches and routers, which must be operated manually. Furthermore, the traditional infrastructure also had a detailed and static design that several protocols deal with various parts of the network. Such structures can complicate the procedure of scaling up or down and moving to the network. Another restriction in the traditional networking infrastructure was the inconsistency in the systems located in several locations without any centralized system to control. Therefore, due to so many reasons, along with many others, the traditional method were falling apart, and it was necessary to make the required changes by implementing modern technologies.
THE DEVELOPMENT OF SDN
The cloud evolution has entered every part of the industry, and it has re-defined the infrastructure, computing, and storage. To implement networking architecture with the enterprise's digital transformation, it was necessary to e-construct the traditional network.
Under such circumstances, the Software Defined Networking (SDN) came as a great help and initiated the Networking Transformation. SDN has efficiently disconnected the forwarding plane from the network structure's controlling plane and offered a software-based technique for managing the network's data flow. This method has successfully substituted the traditional system with centralized control of the network. The solution also offers more flexibility and scalability in the structure, which was hard to achieve earlier.
