High-Level Design (HLD) for Stack Overflow
High-Level Design presents an outline of the complete system, define its all the major components . It would not go into the nitty-gritty information but focuses on the relationships between different-different modules. Here’s a simplified HLD for Stack Overflow:
High Level Design
- Web Servers: Web servers, in the High-Level Design, play a primary function in handling HTTP requests and serving static content. Load balancing guarantees most useful traffic distribution throughout multiple internet servers, contributing to more advantageous performance and availability at the Stack Overflow platform.
- Application Servers: Application servers function as the backbone of enterprise logic and consumer authentication. They interact with database servers and control interactions among various modules. Containerization is leveraged for smooth deployment and scaling, presenting a flexible and scalable structure.
- Database Servers: Database servers save numerous information, and the High-Level Design emphasizes optimized queries and efficient indexing for brief data retrieval. Sharding is employed to distribute data, ensuring scalability as Stack Overflow handles an extensive database of user-generated content material.
- Caching Layer: In the High-Level Design, the caching layer is implemented to optimize performance. Frequently accessed data is cached, reducing the weight on database servers and contributing to an ordinary responsive user experience. Effective cache eviction techniques are mentioned to manipulate memory sources successfully.
- Search Engine (Elasticsearch): Elasticsearch is included as the search engine within the High-Level Design, efficaciously indexing and retrieving relevant effects for questions and solutions. Seamless communication with the Search module guarantees that user get quick result when they use search engine.
- CDN (Content Delivery Network): The Content Delivery Network (CDN) is hired to distribute static assets globally inside the High-Level Design. This international distribution reduces latency and enhances the speed of content material delivery, enhance user experience throughout different regions.
