Dapr Essentials for Java Developers

Build microservices easier and faster with Dapr

Description

Dapr (distributed application runtime) is an open-source, cross-platform runtime for building microservices in different technology stacks.

Additionally, Dapr also offers a set of building blocks. These building blocks provide a solution for some of the challenges one faces when building microservices. Examples include synchronous communication between services (including discovery and resilience), asynchronous communication using the publish/subscribe pattern, storing contextual information in an external state store, handling sensitive data like usernames and passwords, and monitoring the services and all communication between them.

In this workshop, you will learn about Dapr and how to apply Dapr in a step-by-step manner. The workshop consists of several modules. Each module starts with a theoretical part. With some modules, you then take this into practice in hands-on assignments. In these assignments, you apply Dapr yourself and build an entire microservices-based application.

In the hands-on assignments, we use the Dapr Java SDK, but you are free to use the Dapr SDK for the technology stack of your choice. However, if you choose to do so, you are expected to rely on your knowledge of the stack (and the Dapr documentation).
