What is the basic concept of system design?

The basic concept of system design is about architecting a system that meets specific requirements while considering various factors such as scalability, performance, reliability, and cost-efficiency. It involves breaking down a complex system into smaller components, understanding how these components interact, and ensuring the system can handle both current and future needs.

Key Concepts in System Design

1. Scalability: A system must handle growing amounts of work or users. This can be achieved through vertical (adding resources to existing nodes) or horizontal scaling (adding more nodes).

2. Reliability: The system must function correctly under various conditions, ensuring minimal downtime and errors.

3. Performance: The system should operate efficiently with low latency and high throughput.

4. Availability: A reliable system ensures high availability, meaning it remains operational most of the time, even in the event of failures.

5. Fault Tolerance: The system should gracefully handle failures without affecting the overall service.

6. Consistency vs. Availability: In distributed systems, there is often a trade-off between consistency (all nodes see the same data) and availability (system responds to requests even if some nodes fail).

7. Database Design: System design also involves choosing the right type of database (SQL vs. NoSQL), implementing sharding, indexing, and replication strategies to manage data efficiently.
