This repository contains a collection of High-Level Design (HLD) and Low-Level Design (LLD) problems and solutions. It is intended to help engineers, developers, and system architects improve their system design skills through practical examples and detailed explanations.
-
High-Level Design (HLD):
- Concepts, patterns, and solutions for designing scalable, reliable, and maintainable systems.
- Examples of designing distributed systems, microservices, databases, and more.
-
Low-Level Design (LLD):
- Focuses on detailed design aspects, including classes, objects, and interactions within components.
- Covers topics such as UML diagrams, class design, API design, and more.
- A comprehensive collection of HLD and LLD problems based on real-world scenarios.
- Step-by-step breakdowns of design decisions and trade-offs.
- UML diagrams and class-level design details for easy understanding.
- Code snippets and practical solutions for implementation.
- Discussion of system scalability, performance considerations, and fault tolerance.
-
High-Level Design:
- System architecture patterns (e.g., microservices, event-driven architecture)
- Scalability and high availability
- Load balancing and caching strategies
- Fault tolerance and disaster recovery
- Database design and sharding
-
Low-Level Design:
- Object-oriented design principles (e.g., SOLID)
- Class and sequence diagrams
- API design and RESTful services
- Data modeling and relational/non-relational databases
- Caching and optimization strategies
