Site Reliability Engineer (SRE) Roadmap
Learn how Google, Netflix, and top tech companies run resilient systems at scale: SLIs/SLOs, Error Budgets, Incident Command, Toil Automation, and Chaos Engineering.
A roadmap is only worth following for its sequence. Any list can tell you that Kubernetes exists; the useful part is knowing what has to come before it and why.
Curriculum & Milestones (7 Stages)
Stage 1: Engineering Foundations
SRE sits at the intersection of software engineering and operations. You need both.
SRE sits at the intersection of software engineering and operations. You need both.
Understand Google’s SRE philosophy: applying software engineering to operations, treating reliability as a feature, and balancing velocity with stability.
Strong Linux internals, networking and debugging skills are prerequisites for diagnosing production issues under pressure.
SREs write real software to eliminate toil, build tooling and integrate systems. Python and Go are the most common languages.
Stage 2: SLIs, SLOs & Error Budgets
The core language of SRE. Everything else hangs off these definitions.
Stage 3: Monitoring & Observability
You cannot keep a system reliable if you cannot see inside it.
Stage 4: Incident Response & On-Call
How you respond to failure defines your reliability just as much as how you prevent it.
Stage 5: Toil Reduction & Automation
SRE caps manual work and engineers it away.
Stage 6: Reliability & Capacity
Design systems that degrade gracefully and scale predictably.
Stage 7: Release Engineering
Ship changes safely and roll them back instantly when things go wrong.
