Description

Linux is user-friendly and recommended for beginners in the IT field due to its flexibility and open-source nature, allowing customization.


This course is intended to help to understand Linux OS for different domain users like Linux Administrators(Entry level), Platform Engineers, Cloud Engineers, DevOps Engineer and Developers as well.


Even if your specific role isn't listed above, having a basic understanding of Linux can be beneficial for navigating the IT landscape and troubleshooting common issues.


As per Organization requirements, we need to be in a position to handle different scenarios like:

1) Application deployment like Nginx, Apache or Database servers like MySQL, PostgreSQL, etc.,

2) Tools setup and configuration like Docker & Kubernetes, Terraform.

3) Network Configuration on Linux OS.

4) Tools that need to troubleshoot issues on Linux OS.

So we can't say that its administrative task, we as a IT Engineer need to step in when Organization/Team needs help.

This course will help to you to fill that gap with the skillset needed to handle any of the scenarioes mentioned above.


Note: I will be adding more topics on weekly basis for Linux OS

Linux OS (Ubuntu Server 24.04 LTS)

Linux Architecture
