Event Driven Architecture
Event-driven architecture (EDA) is a design principle in which the flow of a system’s operations is driven by the occurrence of events instead of direct communication between services or components. There are many reasons why EDA is a standard architecture for many moderate to large companies. It offers a history of events with the ability to rewind the ability to perform real-time data processing in a scalable and fault-tolerant way. It provides real-time extract-transform-load (ETL) capabilities to have near-instantaneous processing. EDA can be used with microservice architectures as the communication channel or any other architecture.
In this workshop, we will discuss the prevalent principles regarding EDA, and you will gain hands-on experience performing and running standard techniques.
- Key Concepts of Event-Driven Architecture
- Event Sourcing
- Event Streaming
- Multi-tenant Event-Driven Systems
- Producers, Consumers
- Microservice Boundaries
- Stream vs. Table
- Event Notification
- Event Carried State Transfer
- Domain Events
- Tying EDA to Domain Driven Design
- Materialized Views
- Outbox Pattern
- CQRS (Command Query Responsibility Segregation)
- Saga Pattern (Choreography and Orchestrator)
- Avoiding Coupling
- Monitoring Systems
- Cloud-Based EDA

Testing in Scala
by Daniel Hinojosa
If you build your Scala application through Test-Driven Development, you’ll quickly see the advantages of testing before you write production code. This hands-on book shows you how to create tests with ScalaTest and the Specs2—two of the best testing frameworks available—and how to run your tests in the Simple Build Tool (SBT) designed specifically for Scala projects.
By building a sample digital jukebox application, you’ll discover how to isolate your tests from large subsystems and networks with mocking code, and how to use the ScalaCheck library for automated specification-based testing. If you’re familiar with Scala, Ruby, or Python, this book is for you.
- Get an overview of Test-Driven Development
- Start a simple project with SBT and create tests before you write code
- Dive into SBT’s basic commands, interactive mode, packaging, and history
- Use ScalaTest both in the command line and with SBT, and learn how to incorporate JUnit and TestNG
- Work with the Specs2 framework, including Specification styles, matchers DSLs, and Data Tables
- Understand mocking by using Java frameworks EasyMock and Mockito, and the Scala-only framework ScalaMock
- Automate testing by using ScalaCheck to generate fake data
