Overview What You Will Learn Curriculum Instructor

Course Overview

Use a modern language with a focus on simplicity to automate networking tasks. We'll build services that will allow you to reduce or eliminate menial and error-prone tasks, allowing you to focus on the bigger picture problems, all while using a language that is efficient and fun. 

Manually logging into devices is tedious and data may get lost in the process of copying and pasting data from one place to another. A programmatic approach avoids these types of errors. You spend a few cycles developing the logic and writing the code. Then you can rest assured your code will execute and store the information just as you planned it. Building configurations for new devices, or augmenting existing configurations, from an existing device or an existing block of the device, leads to avoidable problems where something does not get modified correctly. In today's world, where many flows ride across an unreliable network, errors are commonplace. We should code for errors. In Go, errors are a primitive of the language with functions normally returning a nil error if successful and a meaningful error otherwise.

This course will walk you through leveraging the power and simplicity of go to make better use of your time at work, reducing the surface for unnecessary errors. This will ultimately open you up for a whole new perspective on how to solve problems big or small.  

What You Will Learn
