This article explores how event-driven architectures can deal with complexity, provide agility, and offer massive scaling potential. It covers the difference between events, commands, and queries, the complexity of event processing, the importance of performance and scale, the various ways to build event flows, the power of quick diagnosis with observability, and the event-powered software design patterns. The author aims to equip every solution architect and software engineer with a proper understanding of event-driven architectures and make them aware of the new challenges that arise with such architectures.
