Part 3: Troubleshooting and Scaling

In this part, the focus shifts towards ensuring the smooth operation of the application and promptly addressing any emerging issues. Emphasis is placed on early issue detection through unit testing. You will delve into creating integration tests using .NET Aspire libraries and implementing end-to-end testing with Microsoft Playwright. The importance of logs, metrics, and distributed tracing, facilitated by Open Telemetry and supported by .NET Aspire, will be explored. Monitoring service interactions, performance metrics, memory consumption, and more during development will be facilitated by the .NET Aspire dashboard. Within the Azure environment, Azure Log Analytics and Application Insights will be utilized, alongside alternative options like Prometheus and Grafana that can be deployed in both on-premises and cloud environments. When scaling services, insights gained from previous chapters will be leveraged, with caution advised when using Azure...
