In this video, we explore the challenges and solutions involved in scaling push notification systems. We focus on the communication between mobile devices and the notification server, discussing different approaches such as polling, long polling (server-sent events), and persistent connections using web sockets. We delve into the benefits and drawbacks of each method, highlighting the need for lightweight client experiences and efficient network bandwidth utilization. Additionally, we address challenges related to load balancing and server failures, offering insights on maintaining stable connections and scaling strategies. References to Netflix's push notification system and other notable systems are provided for further exploration.
