To deliver a large complex application rapidly, frequently and reliably, you often must use the microservice architecture. The microservice architecture is an architectural style that structures the application as a collection of loosely coupled services.

One challenge with using microservices is that in order to be loosely coupled each service has its own private database. As a result, implementing transactions and queries that span services is no longer straightforward.

In this EDA Summit presentation, you will learn how event-driven microservices address this challenge. Chris Richardson, creator of microservices.io, describes how to use sagas, which is an asynchronous messaging-based pattern, to implement transactions that span services.

You will learn how to implement queries that span services using the CQRS pattern, which maintain easily queryable replicas using events.
