Architecture in ULS System ContextULS system characteristics inspire key questions aboutsystems at scale.• What new quality attributes arise due to scale?• What types of analyses are required to understand and designsystems with these characteristics?• What new architecture design principles needed?– E.g., synergy of concerns instead of separation of concerns?• What are the associated architectural tactics, patterns, mechanisms?• What types of analyses and design strategies are needed to design alllevels of systems at scale?– E.g., population dynamics, connectedness/communication• And what expertise is required for this design?Does Scale Really Matter?: ULS Systems Seven Years LaterLinda Northrop: May 24, 201365© 2013 Carnegie Mellon University
