Linux, an open-source operating system (OS), powers 90% of public cloud workloads due to its flexibility and robustness. Understanding Linux is an important prerequisite for working on cloud platforms such as Amazon Web Services (AWS), Apache CloudStack, Rackspace, Google Cloud, and Microsoft Azure.
Let's Talk About Linux:
Linux is an OS used on various computing devices, including computers, servers, mainframes, embedded systems, and mobile devices. It functions similarly to Windows, macOS, and iOS by managing communication between your software and hardware. Without the OS, software wouldn't function. Additionally, there are numerous Linux distributions (distros) available, with Ubuntu being the most widely used. Other distros include Debian, Redhat, and more.
What Should I Learn in Linux?
As someone starting out as a Cloud DevOps Engineer, you don’t need to master every aspect of Linux, but there are essential knowledge you should have, which i have highlighted below
- Linux and OS Installations: It's crucial to understand how Linux installations work. Operating systems (OS) are designed to manage the operation, execution, and processing of virtual machines, virtual servers, and remote infrastructures.
- Command Line Interface: Familiarizing yourself with the Linux command-line interface (CLI), also known as the terminal, equips you to efficiently manage servers, automate tasks, and deploy applications with ease.
- Basic Linux Commands: Leveraging your skills in DevOps, basic Linux commands help you navigate, manage your system, and perform daily tasks quickly and efficiently.
- Files and Directories in Linux: Since Linux revolves around files and directories, understanding their structure and organization is vital for keeping your work organized.
- User/Group/File Permissions: Defining who can read, write, or execute a file or directory determines how users on the system can interact with various files available on it.
- Shell Scripting: For repetitive tasks that may be time-consuming to execute line by line, shell scripts can be used. Understanding this skill helps you automate code compilation processes, run programs, or create program environments.
Conclusion
By acquiring this foundational Linux knowledge, you set the stage for a successful journey into the cloud.
