Network Automation has evolved a lot on the last years, adopting a lot of the practices from SDLC (Software Development Life Cycle) but with the intrinsic constraint of networking services. In this talk you will learn about which are the challenges and common use cases around network automation, for instance: configuration management, user-driven workflows, infrastructure as Code (for hybrid and multi clouds) or close-loop automation using Telemetry. You will realise how a lot of open source projects are coming together to provide solutions to the previous challenges from different angles and how you could connect them together to start building a network automation strategy that could transform your network with lower OPEX, improved reliability and security, and increased innovation.
