But alongside the marketing blitz they also offer certifications for people who are supposed to execute these projects. Even the most foundational certification exam -- which simply tests your recall on what AWS service is for compute versus networking -- teaches and tests you about "Shared Responsibility Model" that draws the line at what the customer is still responsible for when they use cloud bases IaaS / PaaS / SaaS services.

If businesses are going to cloud but without engaging / listening to competent people who know these basics -- then the blame needs to be somewhat pointed back at those very business leaders I feel.
