🗓️ अभ्यास योजना — 12 धडे, 4 आठवडे
~3 sessions a week: read the lesson (~15 min) + run and change its section of sre/demo.py (~25 min). Tick lessons off — progress is saved in this browser.
🐢 स्थिर: आठवड्याला 3 सत्रे → 4 आठवड्यांत पूर्ण.
🐇 वेगवान: प्रत्येक भागासाठी एक weekend → 3 weekends मध्ये पूर्ण.
💰 खर्च: शून्य. तुमच्या लॅपटॉपवर Python 3.
WEEK 1 🛠️ The job and the budget
What SRE is, the error budget policy, toil. Lab: push the crew over the cap; change the SLO and watch the freeze; add your own toil to the ledger.
🏁 Checkpoint: you can explain the 50% cap, what a signed policy does when the budget is spent, and which toil to automate first.
WEEK 2 📟 The phone and the canary
On-call, canary analysis, progressive delivery. Lab: raise the page rate; make the canary bigger; change exposure and rollback time.
🏁 Checkpoint: you can size a rotation, judge a canary with numbers and say which lever cuts a bad change's damage most.
WEEK 3 📈 Capacity, command, the nines
Capacity planning, incident command, reliability math. Lab: forecast further ahead; break a handoff; add services to the chain.
🏁 Checkpoint: you can plan N+2 and zone loss, run an incident with roles, and check whether a design can meet its SLO.
WEEK 4 🧯 Overload, chaos, readiness
Overload, chaos engineering, the PRR. Lab: raise critical traffic; lower the abort line; fail a PRR item and fix it.
🏁 Checkpoint: 🏆 Capstone: write the readiness review for a service you know: its SLO and policy, toil ledger, rotation, canary rules, rollback time, capacity plan, dependency chain, shedding classes and one game-day hypothesis.
