NETWORK DEVOPS COURSE DESCRIPTION This course is not a soft skills course covering the concepts of DevOps but instead concentrates on the technical side of tools and languages for network DevOps. Particular technologies focussed on are ansible, git and Python enabling delegates to leave the course ready to starting automating their network. Hands on sessions follow all major sections. More detailed courses on individual aspects of this course are available. WHAT WILL YOU LEARN * Evaluate network automation tools. * Automate tasks with ansible. * Use git for version control. * Use Python to manage network devices. * Use Python libraries for network devices.
