Dapr (Distributed Application Runtime) is a free and open-source runtime system designed to support cloud-native and serverless computing It provides APIs that simplify microservice connectivity, enabling developers to write resilient and secure microservices.
Dapr abstracts away the complexity of common challenges developers encounter regularly when building distributed applications, such as service discovery, message broker integration, encryption, observability, and secret management It runs as a sidecar wherever your application runs whether hosted on Kubernetes, VMs, deployed on the cloud, on-premises or on the edge.
Although the documentation is great, it can still be a challenge to start building your first dapr enabled application. Therefore I can recommend the Dapr workshop; it contains several hands-on assignments that will introduce you to Dapr. You will start with a simple microservices application that contains a number of services. In each assignment, you will change a part of the application so it works with Dapr. The Dapr building blocks you will be working with are:
- Service invocation
- State-management
- Publish / Subscribe
- Bindings
- Secrets management
It is using a speeding camera setup as the domain, which is interesting enough to show you how Dapr can help in tackling this problem:
