Developing Microservices With Aggregates [Video]

The Domain Model is great, but it complicates microservices. Aggregates can make this process easier, but you'll need to get used to NoSQL and eventual consistency.

The Domain Model pattern is a great way to develop complex business logic. Unfortunately, a typical domain model is a tangled, birds nest of classes. It can’t be decomposed into microservices. Moreover, business logic often relies on ACID transactions to maintain consistency. Fortunately, there is a solution to this problem: aggregates. 

An aggregate is an often overlooked modeling concept from the must read book Domain Driven Design. In this talk, you will learn how aggregates enable you to develop business logic for the modern world of microservices and NoSQL. We will describe how to use aggregates to design modular business logic that can be partitioned into microservices. You will learn how aggregates enable you to use eventual consistency instead of ACID.

We will describe the design of a microservice that is built using aggregates and Spring Cloud.
