SYSTEM DESIGN FUNDAMENTALS

System design is simply about how you plan, structure, and connect different parts of a system so it works efficiently at scale. Think of it like designing a city → roads, buildings, traffic flow, utilities → everything must work together smoothly.

When you build small apps, design doesn’t matter much. But once users grow, things break unless the system is well designed.

WHAT IS SYSTEM DESIGN

System design is the process of defining architecture, components, data flow, and interactions of a system.

You are answering: → How will users interact with the system
→ How will data move
→ How will the system scale
→ How will it stay fast and reliable

HIGH-LEVEL VS LOW-LEVEL DESIGN

HIGH-LEVEL DESIGN (HLD) → Focuses on the big picture
→ Defines system architecture
→ Shows major components and how they connect

Example: → Client → API → Database → Cache

LOW-LEVEL DESIGN (LLD) → Focuses on details inside components
→ Classes, functions, database schema

Example: → How a “User Service” is implemented internally

CORE COMPONENTS OF A SYSTEM

CLIENT → The user interface (web, mobile, etc.)
→ Sends requests to the server

SERVER → Processes requests
→ Contains business logic

DATABASE → Stores data permanently

CACHE → Stores frequently accessed data for speed

LOAD BALANCER → Distributes traffic across servers

HOW A REQUEST FLOWS

User clicks a button
→ Request goes to server
→ Server checks cache
→ If not found → queries database
→ Processes logic
→ Sends response back

This flow must be fast and reliable.

SCALABILITY

Scalability means handling more users without breaking.

VERTICAL SCALING → Add more power to one machine (CPU, RAM)

HORIZONTAL SCALING → Add more machines (servers)

Best practice: → Use horizontal scaling for large systems

LOAD BALANCING

A load balancer spreads traffic across servers.

User requests
→ Load balancer
→ Server 1 / Server 2 / Server 3

This prevents overload and improves availability.

DATABASE BASICS

SQL DATABASES → Structured data
→ Strong consistency
→ Example: MySQL

NOSQL DATABASES → Flexible data
→ High scalability
→ Example: MongoDB

Choice depends on system needs.

CACHING

Caching improves speed by storing frequently used data.

Without cache
→ Every request hits database (slow)

With cache
→ Data served instantly

Tools: → Redis
→ Memcached

CONSISTENCY VS AVAILABILITY (CAP IDEA)

You can’t have everything perfectly.

CONSISTENCY → All users see the same data

AVAILABILITY → System always responds

PARTITION TOLERANCE → System works even with network failures

Trade-offs: → Choose based on your system goals

MICROSERVICES VS MONOLITH

MONOLITH → Everything in one codebase
→ Simple to start
→ Hard to scale

MICROSERVICES → Split into small services
→ Easier to scale independently
→ More complex to manage

RELIABILITY AND FAULT TOLERANCE

Systems fail. Good design expects that.

Use: → Redundancy (multiple servers)
→ Failover systems
→ Monitoring and alerts

Goal: → System should keep running even when parts fail

LATENCY AND PERFORMANCE

Latency = time taken to respond

Improve performance by: → Using caching
→ Reducing database queries
→ Using CDNs
→ Optimizing code

REAL-WORLD THINKING

When designing systems, always ask:

→ What happens when traffic spikes
→ What happens if a server crashes
→ How fast is the response
→ How secure is the system

System design is about thinking ahead.

HOW TO START PRACTICING

Pick simple systems and design them:

→ URL Shortener (like https://t.co/8yL8jJoWz8)
→ Chat System (like WhatsApp)
→ File Storage (like Google Drive)
→ News Feed (like Twitter)

Break them down step by step.

FINAL MINDSET

System design is not memorizing answers.

It is: → Understanding trade-offs
→ Making smart decisions
→ Thinking at scale
→ Designing for failure

MALAYSIA PERKENALKAN DIESEL DARI KELAPA SAWIT

FELDA memperkenalkan minyak alternatif bernama B100 susulan krisis bekalan minyak ketika ini

Minyak itu sepenuhnya daripada kelapa sawit dan merupakan minyak biodiesel pertama di dunia tidak menggunakan elemen minyak fosil

Harga minyak B100 ini dianggarkan RM 4.40 seliter dan lebih murah dari harga diesel ketika ini sekitar RM 6.02 seliter. Pengeluaran Kelapa Sawit sebanyak 20 Juta Tan setahun membolehkan bekalan B100 diberikan cukup untuk keperluan Diesel rakyat Malaysia dari segi teorinya

Namun cabaran utama minyak ini ialah kapasiti pengeluaran yang tidak sebanyak minyak diesel dan permintaan yang rendah

FELDA mencadangkan agar Kerajaan mula memperkenalkan minyak ini di semua stesen minyak dan FELDA sendiri akan mula mengoperasikan minyak ini di semua kilangnya dan elemen logistiknya selepas selesai ujian selama 15 bulan dan 15,000 km perjalanan
