Devops

Learning outcomes

Course Overview:-

The DevOps training helps you become an expert in the principles of continuous development and deployment, automation of configuration management, inter-team collaboration, and IT service agility, using DevOps tools like Git, Docker, Jenkins, Cucumber, Ansible, TeamCity, and Nagios.

Its a culture which promotes collaboration between Development and Operations Team to deploy code to production faster in an automated & repeatable way.In simple words, DevOps can be defined as an alignment of development and IT operations with better communication and collaboration
