I believe both arguments held some merits. It all depend on the scale. If you are a startup and/or have a limited/specialized business scope* Cloud can be the best choice. For organizations of 4000+ people that manage 100+ applications (from different vendors) with a 90+ people IT department this is maybe not the silver bullet. At this scale you need to keep complexity and security manageable and a more traditional redondant datacenter architecture might be less of a headache than the cloud. *PS: What I mean by "limited/specialized business scope" is for instance Twitter/Meta. Huge scale but heavily specialized around their main products and develop most of theirs application in house.
