DevOps is a set of software development practices that combine software development and information technology operations to shorten the systems development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives. Ref: Wikipedia
Now in simple words, You want to deliver your new features & fixes to end users as soon as possible (ideally on daily basis). How is it possible? Yes, It is if you change your development & deployment practices. Automation is Key in achieving this.
In this course, we’ll see different aspects/practices (not in any specific order) to move towards DevOps implementation.
Version Control System
A Version Control System is a Key/Core component in achieving DevOps. Git is a famous distributed version control system. Following are three interactive sessions with developers. (You may check this course as it is in tutorial format)
