It provides a structured curriculum that covers the fundamental architectural strategies necessary for building modern software infrastructure, ranging from high-level system decomposition to low-level networking and data management. The repository distinguishes itself by offering deep dives into complex architectural patterns, such as microservices-based decomposition, event-driven communication, and command-query responsibility segregation. It provides detailed comparisons of API design techniques, including REST, GraphQL, and gRPC, while offering guidance on when to utilize specific patterns like the backend-for-frontend approach or circuit breakers to manage service failures and maintain system stability. Beyond core architecture, the project explores a broad capability surface including infrastructure planning, database sharding, caching strategies, and security standards like OAuth and OpenID Connect. It also addresses operational reliability through service discovery, rate limiting, and disaster recovery planning, providing a technical reference library designed to assist engineers in navigating complex design discussions and technical interviews. ## Tags ### Software Engineering & Architecture - [Distributed Systems Architecture](https://awesome-repositories.com/f/software-engineering-architecture/distributed-systems-architecture.md) — Covers the fundamental principles, patterns, and trade-offs required to design scalable distributed systems. - [API Design Strategies](https://awesome-repositories.com/f/software-engineering-architecture/api-design-strategies.md) — Now that we know how these API designing techniques work, let's compare them based on the following parameters: - Will it cause tight coupling? - How _chatty_ (distinct API calls to get needed information) are the APIs?
