Software-defined networking (SDN) is a novel method used for managing network deployment that allows configurable, dynamic, programmatically responsive network configuration over the internet reducing network downtime, allowing easy maintenance and flexibility, and making it more like clouds than conventional IT management. SDN comprises various elements such as forward and backward compatibility, severe diagnostics, data security, and service discovery. The software-defined networking focuses on enabling easy access to IP networks, irrespective of configuration or location. This technology comes with a unique feature, which is its supports for software as a service (SaaS) applications. With this feature, provider can rapidly build and deploy new custom applications. The applications of SaaS include data-warehousing or business intelligence applications and e-commerce platforms, as well as telematics systems, real-time data analysis tools, and web services for data visualization.
Software-defined networking provides various benefits compared to traditional network architecture. It allows IT professionals of a company to quickly assess and retool its network devices and programs. It allows for simpler upgrades and better scalability. It is significantly cost-effective and time-saving as it eliminates architectures and devices. With SDN, operational stress on network devices is reduced with a reduction in bandwidth requirements and managing device utilization. Moreover, it enhances service quality through improved network, software visibility and device.
Using software-defined networking has provided various business benefits. The most significant benefit it has provided is no requirement of an expensive infrastructure layer. The use of a SaaS-based application framework makes deploying new applications simpler, which improves the company’s ability to add new services and applications quickly and efficiently. Moreover, the management of company’s data becomes easier with the use of a SaaS-based system, which further ensures that the data is safe and secure. The primary benefit of Software Defined Networking is that it provides an unparalleled method of managing the day-to-day operations of an organization. While there are some disadvantages to this type of management, it is undeniable that the benefits far outweigh any negatives. Recently in April 2021, IBM Corporation launched IBM Spectrum Fusion, a new container-native software-defined storage (SDS) solution, for improvement of the management of, and access to, data within increasingly complex hybrid cloud environments for greater data availability and resilience.
