#snsinstitutions #snsdesignthinkers #designthinking WhatsApp is a global messaging platform that demonstrates scalable, real-time communication. It uses end-to-end encryption to ensure secure data transfer between users. The system relies on efficient backend servers, likely built with technologies like Erlang, to handle millions of concurrent connections. A NoSQL approach helps manage unstructured chat data and media files. Features like message delivery ticks, voice/video calls, and status updates enhance user experience. The app is optimized for low bandwidth, making it accessible worldwide. This case study highlights the importance of scalability, security, and performance in modern application design.
