    Keep in mind that the question is broken down into two apps:

    Analytics: Can be run on spot instances since availability can be flexible

    Reporting: Needs to run continuously (spot is not an option)

    The incorrect App Runner answer for the analytics app you pasted does not talk about how to handle failover when the EC2 instance for the reporting application becomes unhealthy (again, needs to be running continuously so a HA/failover mechanism is needed). Fargate will automatically replace unhealthy containers, giving the reporting app HA.

    Therefore the answer for running reporting on spot instances is incorrect because it needs to be running continuously.

    The answer for running reporting on App Runner is incorrect because it says the Analytics app should run on on-demand instance, which is not the most cost-effective option.

    EDIT: Replaced instances with containers in the context of Fargate.
