Modern systems use architectural components like Load Balancers, API Gateways, Backend-For-Frontends (BFFs), and GraphQL to ensure efficient, secure, and customized data delivery. Load Balancers distribute incoming requests across multiple servers for high availability. API Gateways coordinate requests between clients and microservices, centralizing concerns such as authentication and rate limiting. BFFs tailor API responses to specific frontend needs, preventing over-fetching or under-fetching of data. GraphQL allows clients to request precise data, preventing over-fetching, and supports real-time updates. These components work together to enhance performance, scalability, and flexibility in API handling.
