I appreciate the effort put into designing the Sionic Demo Env 2 architecture on GCP, but I have significant concerns regarding the choice of using GCE instances for both web and application layers. While GCE provides flexibility, it introduces operational overhead in terms of scaling, patching, and managing instances.
