90-Day Linux/SRE Mastery Roadmap
A 12-week phased learning plan from Linux comfort to production-grade SRE debugging skill — filesystem, processes, networking, CPU/memory, containers, and observability.
A 12-week phased learning plan from Linux comfort to production-grade SRE debugging skill — filesystem, processes, networking, CPU/memory, containers, and observability.
Deep filesystem, storage, and disk-incident debugging knowledge for production SRE work — FHS, inodes, LVM, RAID, permissions, and a full storage incident debugging playbook.
Navigation map for the Incident Response Mastery series — org-level incident management setup, mindset, hands-on simulations, a 90-day roadmap, and deep Linux/kernel/interview references.
10 timed production incident simulations plus 6 hands-on labs — CPU saturation, disk-full, OOM kills, SYN backlog exhaustion, cgroup throttling, DNS breakage, and more.
End-to-end reference for Linux Administration — filesystem, permissions, process/service management, networking, and interview-ready Q&A.
Master outline of Linux subsystems and tools an SRE must know cold — systemd, CPU/memory/disk, networking, observability, security, containers, boot, and the practical debugging playbook.
Conceptual foundation of how the Linux kernel manages processes, memory, I/O, and hardware — scheduling, user/kernel space, syscalls, interrupts, context switching, and modules.
Command-level and conceptual mastery of Linux process debugging via CLI and /proc — lifecycle, ps/top/kill, decision trees, deep scenarios, and interview Q&A.
End-to-end reference for diagnosing Linux system performance with the USE and RED methods — CPU, memory, disk I/O, network, the standard toolkit, and interview-ready Q&A.
