Contents

• Service invocation
• State management
• Pub/Sub
• Bindings
• Actors
• Observability
• Security
• Middleware
• Components
• Hosting platforms
• Developer tooling

Service invocation

• Invoke other services in your cluster or environment
• Create a gRPC enabled app, and invoke Dapr over gRPC

State Management

• Setup a state store
• Create a service that performs stateful CRUD operations
• Query the underlying state store
• Create a stateful, replicated service with different consistency/concurrency levels
• Control your app's throttling using rate limiting features
• Configuring Redis for state management

Pub/Sub

• Setup Dapr Pub/Sub
• Use Pub/Sub to publish messages to a given topic
• Use Pub/Sub to consume events from a topic
• Use Pub/Sub across multiple namespaces
• Configuring Redis for pub/sub
• Limit the Pub/Sub topics used or scope them to one or more applications

Bindings and Triggers

• Implementing a new binding
• Trigger a service from different resources with input bindings
• Invoke different resources using output bindings

Actors

For Actors How Tos see the SDK documentation

• .NET Actors
• Java Actors

Observability

Metrics and Logs

• Set up Azure Monitor to search logs and collect metrics for Dapr
• Set up Fleuntd, Elastic search, and Kibana in Kubernetes
• Set up Prometheus and Grafana in Kubernetes
• Observe metrics with Grafana

Distributed Tracing

• Diagnose your services with distributed tracing
• Use W3C Trace Context

Security

Dapr APIs Authentication

• Enable Dapr APIs token-based authentication

Mutual Transport Layer Security (mTLS)

• Setup and configure mutual TLS between Dapr instances

Secrets

• Configure component secrets using Dapr secret stores
• Using the Secrets API to get application secrets

Middleware

• Configure API authorization with OAuth
• Apply Open Policy Agent Polices

Components

• Limit components for one or more applications using scopes

Hosting Platforms

Kubernetes Configuration

• Production deployment and upgrade guidelines
• Sidecar configuration on Kubernetes
• Autoscale on Kubernetes using KEDA and Dapr bindings
• Deploy to hybrid Linux/Windows Kubernetes clusters

Developer tooling

Using Visual Studio Code

• Using Remote Containers for application development

• Developing and debugging Dapr applications

• Setup development environment for Dapr runtime development

Using IntelliJ

• Developing and debugging with daprd

SDKs

• Serialization in Dapr's SDKs
