## Babu kyakkyawan tsari

```text
Every design decision involves TRADE-OFFS → improving one thing often costs another:
  → you CAN'T maximize consistency, availability, performance, cost, simplicity all at once
  → "it depends" → the right choice depends on the specific REQUIREMENTS and priorities
→ system design = making informed trade-offs, NOT finding a universal "best" design.
```

## Tradeoffs da aka samu

```text
CONSISTENCY ↔ AVAILABILITY (CAP) → strong consistency vs high availability
LATENCY ↔ CONSISTENCY → caching/replication (fast but possibly stale) vs always-current
PERFORMANCE ↔ COST → more resources/caching cost money
SIMPLICITY ↔ SCALABILITY/flexibility → monolith (simple) vs microservices (scalable, complex)
READ ↔ WRITE optimization → denormalization (fast reads, harder writes) vs normalized
SPACE ↔ TIME → precompute/cache (more storage, less compute) vs compute on demand
→ understanding these lets you choose deliberately.
```

## Kayyaf ake tunani game da tradeoffs

```text
✓ Understand the REQUIREMENTS first → what matters most here? (scale? consistency? cost? latency?)
✓ Identify the trade-offs of each option → what do you gain and give up?
✓ Choose based on PRIORITIES → optimize for what matters; accept costs where they're acceptable
✓ JUSTIFY decisions → explain the reasoning and trade-offs (not just the choice)
✓ Avoid OVER-ENGINEERING → don't add complexity/scale you don't need (YAGNI)
✓ Re-evaluate as requirements change
```

## Me yasa yana da mahimmanci
