Learn the fundamental idea behind Domain-Driven Design (DDD) through a real-world case study from Kleinanzeigen, a leader in online classifieds in Germany. The talk will walk you through a real world example where the Real Estate team at Kleinanzeigen identified a complex business problem and created an improved, effective design that solved inconsistencies in the domain model while at the same time scaled it to future use cases. We will begin by exploring a seemingly simple model of users and ads at Kleinanzeigen which evolved over the years. We will then highlight some of the issues that were being caused by evolving requirements, and how it introduced inconsistencies in the business as the requirements grew more complex. Next, we will learn how the team had an "Aha!" moment that helped them introduce a new concept which not only solved all existing inconsistencies, but also better prepared the business to handle future evolution of business. The talk will not go into definitions of things like entities, value objects etc. that are typical for an introductory Domain-driven Design talk. Rather, it will focus on the core and fundamental idea that Domain-driven Design promotes - understanding user needs and creating values for the customers. This talk is ideal for software developers, architects, and business analysts looking to bridge the gap between complex business domains and effective software solutions.

Abstract: This session is a fast-paced tour of all things Java and Azure at the modern Microsoft of today. We will first talk about the why, how and what of Java and Microsoft. We will then dive right into the broad range of tools, services and APIs that Microsoft offers around Azure for Java developers. We will show a small but representative demo of a Java application most developers would feel familiar with running well on Azure. Lastly, we will discuss the road map for what Java developers can expect from Microsoft in the future. This session is as much about sharing what Microsoft offers today as it is about listening to what the Java community wants to see from Microsoft tomorrow.
