Modern Applications deployed in the cloud are based on serverless or microservices architectures and they are typically fine-grained, distributed, and interconnected. It's perfectly normal to represent those systems in a form of a diagram consisting - more or less - lines and boxes. Lines (connections between boxes that represent components) impose important functional and non-functional characteristics of the systems - like scalability, availability, and coupling. In this session, you will learn how serverless and application integration tools available in the AWS cloud make those connections explicit, automatable, and manageable. In other words: you will learn why lines (integrations) are as just important as boxes (components).
