#twitter #architecture #scalability In this week's video, we do something different than our regular videos. We look into the architectures of one of the giants in the tech industry, Twitter. The architecture that is described in this video is quite old and twitter might have definitely switched to something new by now, but still, the video provides us an insight into system design. We look at how twitter manages its timeline service, the most user-facing side of the entire twitter architecture stack. We see how twitter uses several micro-services and redis cache in order to provide a high speed, low latency response to the user every single time. Hope you like the video.
