Course Curriculum –

Course Introduction

1. How the course is structured and what the learning objectives are.
2. We will try to understand the concepts of DevOps and why it is introduced in IT.
3. We will understand the impact of it in the industry as a whole and how it affects typical job roles.
4. Focus will be on identifying the gaps between current understanding and devops vision.
5. There are several terms in devops such as infrastructure as a code, continuous integration, continuous delivery, continuous testing etc. Understanding them in concept is important.
6. At this part we will try to understand theoretical and philosophical approaches of devops.

Lab Setup

1. Next we will implement all the necessary tools on the lab systems to be able to have a common setup on which we will bring up our systems.
2. We will implement tools that make your windows system behave like linux including even a package management system like yum on your windows system.
3. We will replace your notepad, we will learn to build our laptop as a developer workstation.
4. Systems would be tested at this stage for fitment of doing the lab. In case due to technical limitations, systems are found not to be capable, alternative arrangements can be made (conditions apply).
