Step 1: Understand the Basics of System Design

Before you begin creating your system design portfolio, it’s essential to have a solid understanding of system design fundamentals. System design involves planning and structuring complex systems to meet specific requirements, balancing trade-offs like scalability, reliability, and maintainability.

Key Concepts to Learn:

Scalability: The ability of a system to handle increased load without sacrificing performance.
Reliability: Ensuring the system works as expected, even under unexpected conditions.
Maintainability: How easily the system can be modified or updated.
