Event Driven Microservices Architecture with .NET and Docker

Package all relevant modules into a single execution unit to form a deployable monolithic application with independent layers for the user interface, application logic, and data access.

Describe a microservices architecture as a collection of autonomous, small services each implementing an individual business functionality within a bounded context that defines the domain model.

Create an infrastructure diagram in Draw.io for an event-driven Azure microservices architecture, detailing API gateway, Azure Service Bus, SQL, Cosmos DB, storage, Azure Function, and application insights.

Learn how microservices exchange information through an event-based architecture using a topic and subscriptions, tracing from the api gateway to transaction, balance, transfer, and notification services.

Explore Terraform structure for Azure deployments, defining providers and resources, and using init, plan, apply, destroy, and validate workflows with a service principal for RBAC.

Delete and re-provision databases to control monthly costs, using Terraform destroy or apply on targeted resources, and optionally comment out definitions before re-enabling when the course resumes.

Provision an Azure storage account with Terraform, naming it storage_account_function in the West US region using the resource group, then run plan and apply and verify in the Azure portal.

Create a gateway API endpoint to receive transfer requests, modeling an endpoint with customer id, transfer amount, source and destination accounts, and map a post route that returns the model.

Create architecture by scaffolding a bank transaction API in ASP.NET Core and organizing the project into domain, persistence, external, application, and features folders.

Configure and secure the transaction database for the microservice by provisioning it in the Azure portal, enabling SQL authentication, whitelisting your IP, and creating the transaction table with key fields.

Create a transaction entity in the domain layer and configure a SQL Server EF Core database context with a DbSet, enabling save changes async and dependency injection.

Implement an integration test in a minimal API by wiring a database service, calling the async data interface, and displaying results in the browser to verify database integration.

Configure and create the transfer table in the SQL database for the transfer microservice via the Azure portal, firewall rules, and Terraform credentials.

Demonstrates integration testing for a .NET microservice by wiring a database service into a minimal API, querying the transfer table asynchronously, and validating the database connection.

Run integration tests to save and retrieve a notification entity in Azure Cosmos DB, using the database service add async, then fetch and verify the persisted data.
