SDN transition is a journey. It will take time, resource, and preparation before organizations introduce virtualization and automate it into data infrastructure. That said, the first step is to put the following benefits into context.
- 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.
Unfortunately, SDN is evolving at a relatively slow pace. Most of the enterprises with highly virtualized data centers often face deployment challenges in their quest for a rapid deployment, more automation, and more granular configurations. There are several open source orchestration tools that are available for free download. However, interoperability issues still persist.
