I'm facing an issue where my Java microservices, developed with Spring Boot, are successfully starting in the development environment but failing to do so in the Azure test environment. We're deploying these microservices in Azure App Services, and we have separate Resource Groups for development and testing. Both are set up with the same configurations and contain six microservices, a database, and a static front-end page. The development group is stable and responsive, but the testing group keeps restarting and won't start the applications. We've optimized the connection pool and configured all Spring beans to load lazily to speed up startup. We also included an actuator for health checks, but nothing seems to help. Notably, one service that starts in about 6 seconds locally fails to do so in Azure. The JAR files are small, averaging around 75 KB, and our gateway is even lighter at 42 KB. I'm looking for suggestions on why the Stage Resource Group is failing to start the services when the configurations are essentially identical.

First off, which tier are you using for your App Service plan? Also, is it running on Windows or Linux? Those are key points that can affect performance. Have you looked into the app service logs? They might provide some insight into why w3p is causing issues.
Since the environments are mirrored, I’d recommend checking the environment variables and configurations closely. Sometimes, slight differences can cause issues. Additionally, ensure there aren't any network security groups or firewalls that might prevent the Stage Group from reaching necessary resources.
