System Design

Every scalable system eventually chooses:

speed, cost, or correctness.

You only get two at a time.

The best diagrams answer one thing clearly.

Everything else is noise.

#SoftwareArchitecture

Scaling isn’t adding servers.

It’s removing assumptions you didn’t know you made.

#SystemDesign #DistributedSystems

Scaling a system is easy.

Scaling without breaking trust
is the real challenge.

#SystemDesign #DistributedSystems

Good System Design is invisible.

Users only notice it
when it’s missing.

#SystemDesign #SoftwareEngineering

Great System Design answers sound unsure
because good engineers explore options
before locking decisions.

Certainty too early is a red flag.

Most outages are not bugs.

They’re design decisions made months ago
finally showing their cost.

#SystemDesign #Production

If your architecture needs
10 diagrams to explain,
it already failed.

#SystemDesign #Architecture

Simpler systems scale better
because fewer things can break.

Complexity is expensive.

The best System Design interviews
sound like conversations — not lectures.

Think aloud. Debate trade-offs.

Caching doesn’t fix bad design.

It hides it… until traffic spikes.

#SystemDesign #Backend

At scale, failures are normal.

The only question is:
❌ Will users notice?

Design decides the answer.

#DistributedSystems #SystemDesign

It’s about trade-offs under constraints.

Anyone can draw boxes.
Engineers explain why those boxes exist.

System Design question 👇

What’s harder at scale?

• Database design
• Caching strategy
• Observability
• Distributed failures

#SystemDesign #TechTwitter

System Design is not about drawing boxes.

It’s about latency, scale, failures, and trade-offs.

Design for failure — success follows.

📊 System Design Diagram

Client → Load Balancer → Service → Cache → DB

Most performance issues hide in this flow, not the code.

Ask yourself:
• Where is latency added?
• What fails first?

Diagrams reveal truth.

#SystemDesign #Architecture

Strong consistency feels safe.
Eventual consistency feels scary.

But at scale, availability often matters more than immediacy.

System Design is choosing when users can be wrong.

#SystemDesign #DistributedSystems

Choosing a database is a business decision, not a tech one.

Ask this before picking DB 👇
• Read vs Write heavy?
• Strong vs Eventual consistency?
• Query patterns?

Wrong DB = permanent pain.

#SystemDesign #Databases #designsystem

#Caching

Most systems fail not because of traffic
but because of bad cache design ⚠️

Key rules 👇
• Cache hot data, not everything
• TTL ≠ correctness
• Always design for cache miss

Cache is a performance tool, not a shortcut.
