SDN will have a huge impact on the role of a majority of networking professionals, especially networking engineers who haven’t dwelled much into newer technology. Even for virtualization-savvy pros, SDN will still present challenges because, in the processes of simplifying the interface, software-defined networking puts an additional layer on top of the already complex network.
- Augmented Automation
Automation empowers companies to create a more consistent and predictable environment that promotes scalability. This makes it possible to manage different traffic situation.
- Centralized Networking Control
Centralized network management allows for efficient distribution of traffic. This eliminates chokepoints thus improving application performance. With a central console, an organization can manage infrastructure (storage, networks, and servers) more effectively.
- Improved Security
Virtualization may complicate management, but it gives more powers to IT administrators to control the network. Having a centralized network control system creates a central point of monitoring to distribute policy and security information through the organization.
- Reduce Expenses
Centralized network management leads to better hardware use and operational efficiency. It is also possible to extend the lifespan of existing hardware because you are relying more on the SDN controller.
