Site Reliability Architect
Site Reliability Architects operate at the intersection of engineering leadership and operations, setting reliability standards across the entire organisation. Their English communication includes writing SLO policies for executive review, presenting error budget reports to product leadership, and authoring reliability roadmaps that influence engineering priorities.
Topics covered
- SLO & Error Budget Design
- Toil Reduction Strategy
- Capacity Planning
- Chaos Engineering
- Reliability Roadmaps
- Incident Management
Vocabulary spotlight
4 terms every Site Reliability Architect should know in English:
The acceptable amount of downtime or errors derived from the SLO that a team may consume before reliability work takes priority
"We burned 80% of the monthly error budget in the first week — feature work is paused."
Manual, repetitive, automatable operational work that scales linearly with service growth and provides no lasting value
"Manual certificate rotation was pure toil — we automated it and reclaimed 6 hours per week."
The practice of intentionally injecting failures into a system to discover weaknesses before they cause real incidents
"Chaos engineering revealed that the payment service had no fallback when the fraud-check service timed out."
The scope of impact when a failure or change goes wrong, used to assess risk and design containment strategies
"We limit the blast radius of config changes by deploying to 5% of pods before a full rollout."

Frequently Asked Questions
What English skills do Site Reliability Architects most need to improve?+
Site Reliability Architects most commonly need to improve: technical vocabulary (the correct English terms for domain concepts), collocation accuracy (using the right verb for each action), written communication (bug reports, PR descriptions, technical docs), and spoken communication for standups, code reviews, and stakeholder meetings.
How long does the Site Reliability Architect learning path take?+
The Site Reliability Architect learning path contains 20–40 hours of material studied comprehensively. Most learners focus on the highest-priority modules first and return to the rest over time. Spending 30 minutes per day for 4–6 weeks produces noticeable improvement in workplace English.
What vocabulary should a Site Reliability Architect prioritise first?+
Start with the vocabulary that appears most in your daily work — terms you read in documentation, use in commit messages, and hear in meetings. The Site Reliability Architect path begins with the most frequent vocabulary clusters before moving to advanced communication patterns.
Are there interview exercises for Site Reliability Architect roles?+
Yes. The Site Reliability Architect path includes role-specific interview question modules with model answers and key phrases — the actual questions interviewers ask and the vocabulary needed to answer them fluently. There is also a dedicated Interview Practice hub for general interview skills.
Does this path include pronunciation help?+
Yes. The path links to pronunciation exercises for the technical terms most commonly mispronounced in this domain. The Pronunciation hub includes drills for acronyms, silent letters, word stress, and minimal pairs — all in IT context.
What are the most common English mistakes Site Reliability Architects make?+
The most common mistakes: incorrect collocations (using the wrong verb with a technical noun), false friends from L1, tense errors when narrating past incidents or walkthroughs, and using overly formal or overly casual register in written communication.
How do I improve my English for code reviews?+
Learn the standard code review collocations: approve a PR, request changes, leave a nit, address feedback, block a merge, resolve a conversation. Use hedging language for suggestions: "This might be cleaner as…", "Have you considered…?". The Collocations section includes a dedicated Code Review set.
Can I use this path alongside my daily work?+
Yes — the path is designed for working professionals. Each exercise set takes 10–15 minutes. The most effective approach is to study a vocabulary module before a meeting or task where you'll use that vocabulary, then practise immediately after. Context-linked practice produces much faster retention.
Is the content free?+
Yes, completely free. No registration required, no payment, no time limit. All vocabulary modules, exercises, glossary entries, and learning path guides are open access.
How do I track my progress through this path?+
Progress is tracked in your browser's local storage — completed exercise sets are marked with a checkmark when you return. No account is needed. You can bookmark specific modules and use the exercises overview to see which sets you've completed.
