SpringSpring BootCode Review

It is known that the service is deployed in several instances. How will this code work? What is the problem, and how can it be solved?

@Service
public class Foo {

    @Scheduled(at night)
    public void scheduleFixedDelayExercise() {
        var result = doHardSqlAction();
        var file = doHardFileAction(result);
        saveFile(file);
    }

    private Object doHardSqlAction() {
        ...
    }

    private Object doHardFileAction(Object result) throws Exception {
        ...
    }

    private void saveFile(Object file) {
        ...
    }
}
