The entire networking industry is being pressured to automate to scale and move faster. In modern networks, you just can't manage everything by hand anymore. You need to automate relentlessly, and the most practical way to do so is with YANG and NETCONF. But existing documentation on these technologies has been poor, jargon-filled, or non-existent, so most implementers have been forced to learn by trial and error. Now, Network Programmability with YANG gives them comprehensive and reliable guidance for unlocking the power of network automation using model-driven APIs and protocols. Written by three leaders of the YANG development effort, this plain-spoken book guides networking professionals in successfully applying software practices based on YANG data models. The authors focus on the network operations layer, emphasizing model-driven APIs and underlying transports. Using their information and insights, network professionals can transform the way they manage large networks.
