How do messaging app backends enable instant communication? Are they built on persistent socket connections or rely on standard HTTP interactions, and how is message status and large-scale performance managed?
i guess they rely on both: websockets for that rapid back-and-forth and http backups for reliability. they use clusters and caching to manage mess status even in failovers. pretty cool device mix, huh?
hey, i think messaging backends tend to use websokets to keep connections open for real time msgs, with http playing a role in non-critical tasks, and they rely on distributed systems for load. how do u feel about the trade-offs in handling failovers?
In my view, modern messaging backends integrate persistent connections with HTTP-based fallbacks to ensure swift and reliable message delivery. Real-time communication is typically maintained through persistent socket connections, which allow for instant updates, while HTTP interactions handle tasks such as message state updates and backups in cases of connectivity issues. Experience has shown that scaling these systems across clusters and data centers using distributed architectures not only improves performance but also secures data integrity during failovers. This combined method has proven effective in maintaining both speed and reliability on a large scale.
