Master System Design: Key Concepts, Best Practices, and Real‑World Resources
This article introduces the open‑source system‑design‑101 repository, explaining why learning system design matters, and walks through essential topics such as API performance, the CAP theorem, caching strategies, microservice best practices, and secure password storage, with links to video courses and the project’s GitHub address.
Project Introduction
The open‑source system‑design‑101 repository (over 46k stars on GitHub) uses diagrams and concise text to make complex system‑design principles easy to understand, benefiting both interview preparation and daily engineering work.
Video courses related to Java architecture and advanced topics are also listed:

Why Learn System Design
Interviewers often ask system‑design questions.
Future architects need a solid foundation in system design.
Staying only at CRUD level is insufficient in today’s competitive environment; understanding middleware and architectural principles is essential.
Project Showcase
How to Improve API Performance?
When building APIs, response speed directly impacts user experience. The repository suggests several optimization techniques.
CAP Theorem
The CAP theorem states that a distributed system can simultaneously satisfy at most two of the three properties: Consistency, Availability, and Partition tolerance.
Caching Strategies
Caching is a common technique to boost performance and is frequently asked about in interviews, including consistency between cache and database.
Microservice Best Practices
Microservices dominate modern architectures. When building a project from scratch, decisions about service decomposition are critical, and interviewers often probe this area. The repository provides recommended practices.
How to Store Passwords Securely
Passwords must never be stored in plain text; choosing an efficient and secure hashing algorithm is essential.
