Architecting Your Customer Notification Strategy w/ Sandor Nyako | LinkedIn Engineering
In the past, each LinkedIn application team decided their notification strategy in isolation. Business logic and infrastructure sharing were limited between the teams. This resulted in a fragmented and inconsistent tech stack across LinkedIn and a less than savory member notification experience. To combat this disjointed experience, Linkedin set up a small team to build an orchestration layer, the Air-Traffic Controller (ATC). This became one of the more complex notification systems and helped Linkedin grow into the top social platform for business and networking.
