Across industries, IT networks are becoming more complex. The number of users, the number of devices and the amount of bandwidth being consumed are all growing at exponential rates. But resources dedicated to the network largely remain flat. At some point, something has to give.
The only way to battle complexity is with the simplicity offered by features such as automation and orchestration. This is where software-defined approaches to networking come in. Particularly, the software-defined access approach pioneered by Cisco Systems (SD-Access, or SDA) can simplify network deployment and management, freeing up more time for IT departments to focus on strategic projects.
