Visão Geral

EsteJunos Platform Automation And DevOps Foundatioin, demonstra como automatizar o SO Junos usando ferramentas, protocolos e tecnologias de automação DevOps. Este curso 
introduz os princípios básicos DevOps, Junos APIs, e o Protocolo de Configuração de Rede (NETCONF). Ele se concentra no uso do Python, Junos 
PyEZ, Ansible, and the Junos Representational State Transfer (REST) API para automatizar as plataformas Junos. Extensible Markup Language (XML), 
JavaScript Object Notation (JSON), e YAML Ain't Markup Languate (YAML) são introduzidos como formatos de dados que facilitam a automação de Junos. 
Através de demonstrações e laboratórios práticos, os estudantes ganharão experiência na automatização do sistema operacional Junos. Este curso utiliza o sistema operacional Junos 
Release 20.2R2.11, Python 3.6.8, Junos PyEZ 2.54, e Ansible 2.9.5
