System design is a crucial skill for software engineers, especially those aiming for senior roles or preparing for technical interviews. It involves designing scalable, high-performance, and reliable systems. This roadmap will guide you from the basics to advanced concepts, helping you build a strong foundation in system design.
📌 Why Learn System Design?
- Essential for Scalable Applications – Helps in building high-performance, fault-tolerant systems.
- Tech Interviews & Job Promotions – Common in FAANG and top-tier tech interviews.
- Better Engineering Decisions – Aids in choosing the right architecture, database, and caching strategies.
📍 System Design Roadmap
1️⃣ Fundamentals of System Design
Before diving into large-scale systems, you must understand the basics:
🔹 Client-Server Model – Understand how requests and responses work.
🔹 Latency vs. Throughput – Learn the trade-offs between response time and request handling capacity.
🔹 CAP Theorem – Understand Consistency, Availability, and Partition Tolerance.
🔹 Database Basics – Learn SQL vs. NoSQL, indexing, and query optimization.
✅ Resources: Read “Designing Data-Intensive Applications” by Martin Kleppmann.
2️⃣ Scalability and Performance Optimization
Building a scalable system requires proper resource management and architecture:
🔹 Load Balancing – Distribute traffic using round-robin, least connections, and IP hash.
🔹 Database Scaling – Vertical vs. Horizontal scaling, sharding, and replication.
🔹 Caching Strategies – Use Redis or Memcached to reduce database queries.
🔹 CDN (Content Delivery Network) – Improve speed by caching content globally.
✅ Hands-on Practice: Set up a simple load-balanced system using Nginx and Redis.
3️⃣ Microservices & Distributed Systems
Modern applications rely on microservices for flexibility and scalability:
🔹 Monolith vs. Microservices – Learn when to choose each approach.
🔹 API Gateway & Service Discovery – Manage communication between services.
🔹 Event-Driven Architecture – Use Kafka or RabbitMQ for asynchronous processing.
🔹 Failure Handling & Circuit Breakers – Implement retry logic and fault tolerance.
✅ Practice: Design a microservices-based e-commerce system with API Gateway.
4️⃣ Storage & Database Design
Choosing the right storage solution impacts system performance:
🔹 SQL vs. NoSQL Databases – MySQL, PostgreSQL vs. MongoDB, Cassandra.
🔹 Partitioning & Replication – Ensure high availability and redundancy.
🔹 Data Warehousing & Analytics – Use tools like BigQuery, Snowflake.
🔹 Time-Series Databases – For logs and monitoring, consider InfluxDB or Prometheus.
✅ Exercise: Design a real-time analytics dashboard for user activity tracking.
5️⃣ Security & Reliability
Security is crucial for protecting data and user privacy:
🔹 OAuth & JWT – Secure authentication and authorization.
🔹 Rate Limiting & DDoS Protection – Prevent abuse with throttling mechanisms.
🔹 Zero Trust Architecture – Minimize security risks with strong access controls.
🔹 Backup & Disaster Recovery – Plan for failures with automatic backups and recovery strategies.
✅ Task: Implement OAuth2-based authentication for a REST API.
6️⃣ Real-World System Design Case Studies
Learning from real-world architectures helps in better decision-making:
🔹 Designing a URL Shortener (e.g., Bitly)
🔹 Building a Scalable Chat System (e.g., WhatsApp)
🔹 Designing a Video Streaming Platform (e.g., YouTube, Netflix)
🔹 Architecting an E-Commerce System (e.g., Amazon, Flipkart)
✅ Challenge: Try designing an Instagram-like social media platform.
