Wednesday Morning English — System Architecture 🏗️

Good morning! Today is Wednesday, and we’re diving into System Architecture — the language used by engineers who design scalable, reliable, cloud-native systems. Whether you’re in a design meeting, writing an RFC, or discussing tradeoffs, these words will help you communicate with confidence.

🌟 Word of the Day: Resilience

IPA Pronunciation	/rɪˈzɪl.i.əns/
Vietnamese	Khả năng phục hồi / Tính bền vững
Part of Speech	Noun (uncountable)
Stress	re-ZIL-i-ence

How to Pronounce It

Break it into 4 syllables: re · zil · i · ence

• re — like the “re” in return (short, unstressed)
• ZIL — rhymes with will, fill, still (this is the stressed syllable — say it louder and longer)
• i — very short, like the “i” in it
• ence — rhymes with fence, hence (soft ending)

🎯 Full practice sentence (read aloud 3 times slowly):

“Resilience is the foundation of every fault-tolerant distributed system.”

📖 Example Sentences

1. Design review context:

   “We need to improve the resilience of our payment service — if the database goes down, the whole checkout flow fails.”

2. Job interview context:

   “I redesigned the retry mechanism to add resilience against transient network failures in our microservices.”

3. Architecture meeting:

   “The new event-driven approach gives us more resilience because services can process messages asynchronously and recover independently.”

Phrase	Vietnamese	Example in Context
fault tolerance	Khả năng chịu lỗi	”Our system achieves fault tolerance by replicating data across three availability zones.”
horizontal scaling	Mở rộng theo chiều ngang	”We switched to horizontal scaling by adding more pods instead of upgrading the server.”
eventual consistency	Nhất quán cuối cùng	”In this distributed cache, we accept eventual consistency to achieve lower latency.”
load balancing	Cân bằng tải	”The load balancer distributes traffic evenly across all healthy backend instances.”
single point of failure	Điểm lỗi đơn lẻ	”The database was a single point of failure, so we added a read replica for redundancy.”

✏️ Exercise 2 — Translate to English

Translate these Vietnamese sentences into natural English. Use the vocabulary from today’s lesson.

1. “Hệ thống của chúng ta cần khả năng phục hồi cao hơn khi các dịch vụ phụ thuộc bị lỗi.”
2. “Cân bằng tải giúp phân phối traffic đều giữa các server.”
3. “Đây là điểm lỗi đơn lẻ — chúng ta cần thêm một replica.”

✅ Click to reveal model answers

1. “Our system needs greater resilience when dependent services fail.” (Alternative: “We need to improve our system’s resilience against downstream service failures.”)

2. “Load balancing helps distribute traffic evenly across servers.”

3. “This is a single point of failure — we need to add a replica.”

💡 Idiom of the Day

”Don’t put all your eggs in one basket”

Vietnamese	Đừng bỏ tất cả trứng vào một rổ
Architecture meaning	Avoid depending on a single server, service, or region — spread the risk

Examples

1. General use:

   “We store backups on three different cloud providers — we don’t want to put all our eggs in one basket.”

2. In a design review:

   “Deploying everything to a single availability zone is like putting all your eggs in one basket. What happens when that AZ goes down?”

🎯 Today’s Architecture Challenge

Tiny action — takes only 5 minutes:

Open a design doc, README, or Slack message you wrote recently. Find one technical concept you described in Vietnamese or in vague English (like “it crashes sometimes”). Rewrite that one sentence using today’s vocabulary — for example, using resilience, fault tolerance, or single point of failure.

Example: ❌ Before: “The service sometimes breaks when the DB goes down.” ✅ After: “The service lacks resilience — it has no circuit breaker to handle database unavailability.”

Share your rewritten sentence with a colleague or just save it. Small rewrites build big habits! 💪
