import com.example.serverlesscomponent.MessageQueue;
import akka20future.Future;
public class Producer {
def produceMessage(msg: String) throws Future Exception {
MessageQueue.send(“topic”, msg.toString());
}
}
And a consumer:
java // src/main/java/com/example/serverlesscomponent/Consumer.java
import com.example.serverlesscomponent.MessageQueue;
import akka20future.Future;
public class Consumer {
Future
return MessageQueue.receive(“topic”);
}
}
`

ruth -G main:run-deployment
ruth -A
- Define deployment steps within the action configuration (e.g., `.github/workflows`).
name: Deployment Workflow
on:
push:
branches: [main]
jobs:
deploy:
runs-on: ubuntu-latest
Step 4: Executing the Deployment Pipeline
Execute your CI/CD workflow to automate deployment.
- Commit and Push changes to `src/main.tsx` in a controlled manner.
- Run GitHub Actions or manually trigger the workflow using an SSH command (e.g., `git checkout main && git remote add origin https://username:password@github.com/repo.git; ./deploy.sh`).
Step 5: Monitoring and Reporting
After deployment, monitor application performance, logs, and health metrics.
- Set up monitoring tools like Prometheus for logging or CloudWatch for AWS-based applications.
