Operations
Develop operational Linux skills including system administration, performance tuning, troubleshooting, and shell scripting. Mastering these topics is essential for any platform engineer or systems administrator aiming to maintain highly available and performant Linux environments.
In this section, you will explore the critical day-to-day operations required to manage enterprise Linux systems. From understanding storage and network administration to managing software packages and user access, these modules lay the groundwork for robust infrastructure management.
You will also find advanced sub-sections dedicated to performance analysis, systematic troubleshooting, and automation through shell scripting. Together, these topics ensure you can diagnose issues quickly, optimize resource utilization, and automate repetitive tasks at scale.
After Security and Hardening, follow the modules in this order: System Administration (8.x) → Performance → Troubleshooting → Shell Scripting.
