Top 20 System Design Concepts You Should Know

Top 20 System Design Concepts You Should Know

1 - Load Balancing: Distributes traffic across multiple servers for reliability and availability.
2 - Caching: Stores frequently accessed data in memory for faster access.
3 - Database Sharding: Splits databases to handle large-scale data growth.
4 - Replication: Copies data across replicas for availability and fault tolerance.
5 - CAP Theorem: Trade-off between consistency, availability, and partition tolerance.
6 - Consistent Hashing: Distributes load evenly in dynamic server environments.
7 - Message Queues: Decouples services using asynchronous event-driven architecture.
8 - Rate Limiting: Controls request frequency to prevent system overload.
9 - API Gateway: Centralized entry point for routing API requests.
10 - Microservices: Breaks systems into independent, loosely coupled services.
11 - Service Discovery: Locates services dynamically in distributed systems.
12 - CDN: Delivers content from edge servers for speed.
13 - Database Indexing: Speeds up queries by indexing important fields.
14 - Data Partitioning: Divides data across nodes for scalability and performance.
15 - Eventual Consistency: Guarantees consistency over time in distributed databases
16 - WebSockets: Enables bi-directional communication for live updates.
17 - Scalability: Increases capacity by upgrading or adding machines.
18 - Fault Tolerance: Ensures system availability during hardware/software failures.
19 - Monitoring: Tracks metrics and logs to understand system health.
20 - Authentication & Authorization: Controls user access and verifies identity securely.
