This conference talk by Sigal Weiner, VP Engineering at DevOpsDays Tel Aviv, explores the operational evolution required when scaling from a single-server application to a large-scale AWS service. Discover how operational processes, on-call models, and stability strategies must adapt to match growing service complexity. Learn through real-world experiences what approaches worked and failed during this scaling journey, with insights on how support systems evolved alongside the technical architecture. Gain valuable perspective on key operational considerations for scaling services, emphasizing that successful scaling requires contextual solutions rather than universal approaches. The 27-minute presentation provides practical wisdom for engineering teams facing similar growth challenges.
