software-defined networking

Lower operational expenses: This benefit is a consequence of the previous two benefits. Reduction in time, errors, and improved efficiency make the network fast and agile, which in turn aids application development and deployment initiatives. Businesses are thus able to achieve faster results at reduced costs. Automation also cuts down the resources that need to be allocated to repetitive network tasks and puts them instead to good use, resulting in further cost savings. With enterprises increasingly realizing the value in automating networks, there are several methods, tools, platforms, and software for both CLI-based and GUI-based automation.

As discussed in a previous section, CLI is traditionally used as the means for network automation, but it requires scripting knowledge, which makes it a poor choice for complex networks. However, there are open-source tools such as Red Hat Ansible, Chef, and Puppet that provide a library of CLI-based commands that can be deployed, modified, and reused for various tasks.

An improvement from CLI-based tools is proprietary GUI-based software offered by network device vendors. Though these GUI-based software greatly simplify network management and automation, they’re vendor-specific. This can prove to be very expensive for enterprises that employ network devices by different vendors, as they have to invest in a multitude of such software.
