In Part 3 of Building Microservice Applications with Azure Container Apps and Dapr, we cover communication between microservices in Azure Container Apps. We add a new microservice named “ACA WebApp-Frontend” and illustrate it in the architecture diagram. We also look at setting up the Web App Frontend Project by creating an ASP.NET Core Web App project and adding models (DTO). The source code for this tutorial is available on GitHub and you can check the demo application too. Additionally, we cover topics such as deploying backend API Microservices to Azure Container Apps, Dapr integration with Azure Container Apps, Azure Container Apps state store with Dapr state management API, Azure Container Apps async communication with Dapr pub/sub API, Azure Container Apps with Dapr bindings building block, Azure Container Apps monitoring and observability with Application Insights, continuous deployment for Azure Container Apps using GitHub Actions, use Bicep to deploy Dapr Microservices Apps to Azure Container Apps, Azure Container Apps auto scaling with KEDA, Azure Container Apps volume mounts using Azure Files, and integrate health probes in Azure Container Apps.
