The operations manager asks you for a list of recommended practices that she should consider when migrating a J2EE application to the cloud. Which three practices should you recommend? (Choose three.)

When migrating a J2EE application to the cloud, instrumenting the application with a monitoring tool like Stackdriver Debugger (now Cloud Debugger) is crucial for identifying and resolving issues in the cloud environment. Selecting an automation framework ensures consistent and reliable infrastructure provisioning, reducing manual errors and speeding up deployments. Deploying a continuous integration tool with automated testing in a staging environment is essential for maintaining code quality, detecting regressions early, and ensuring the application functions correctly before production deployment. Porting the application code to App Engine might be a good long-term strategy but isn't a universally applicable "recommended practice" for migrating an existing J2EE application, which often involves re-platforming or re-hosting first. Integrating Cloud Dataflow for real-time metrics is an advanced analytics solution, not a fundamental migration practice. Migrating from MySQL to a NoSQL database is a significant architectural change, not a general best practice for all migrations, especially if the application relies on relational data models.
