Network Programmability Overview

Rapid technological advancements, increased application demands, and the widespread adoption of technologies like cloud computing, the Internet of Things, and everyday gadgets have resulted in more complex and demanding networking. As a result, the evolution of networking has led to the integration of programmability into network devices, aligning with industry trends toward automation and efficiency. 

Network programmability aims to reduce human-to-machine interactions and expedite automation, addressing challenges in large-scale service delivery. Unlike current practices that involve manual configurations through the Command-Line Interface (CLI) and text editors like Notepad, programmability tools automate tasks and utilize version control systems for configuration management.   

This approach enhances efficiency, minimizes errors, and ensures repeatability in network operations. It's driven by the need to scale networks seamlessly, accelerate service delivery, and adapt to the demands of modern infrastructures, incorporating concepts from Software-Defined Networking (SDN), agile development, and IT operations.
