Dapr- Distrbuted Application Runtime. .Net Summit 2020_ Bangalore
- 1. Distributed Application Runtime An Event Driven, portable runtime for building microservices on cloud and edge • Amresh Krishnamurthy • Amresh.Kris@gmail.com • @amreshkris
- 2. What is holding microservice development back? Hard to incrementally migrate from existing code to a microservices architecture Programming model runtimes have narrow language support and tightly controlled feature sets Runtimes only target specific infrastructure platforms with limited code portability across clouds and edge
- 3. Secrets Securely access secrets from your application Distributed tracing See and measure the message calls across components and networked services Actors Encapsulate code and data in reusable actor objects as a common microservices design pattern Resource bindings and triggers Trigger code through events from a large array of inputs Output bindings to external resources including databases and queues Publish and subscribe Secure, scalable messaging between services State management Create long running, stateless and stateful services Microservice building blocks Service-to- service invocation Perform direct, secure, service- to-service method calls
- 4. Dapr Goals
- 5. Service- to- service invocation State management Publish and subscribe Resource bindings and triggers Actors Distributed tracing Secrets Extensible Any cloud or edge infrastructure HTTP API gRPC API Application code Any code or framework… Microservices written in Dapr: Distributed Application Runtime Build apps using any language with any framework
