AI systems require robust infrastructure foundations to succeed at scale. While organizations chase AI capabilities, they often neglect the critical middle layer of CI/CD pipelines, observability, governance, and trust mechanisms. The article uses a cake metaphor where AI is the sugar (frosting) but CI/CD infrastructure is the sponge that provides structural integrity. Real-world examples like Air Canada's chatbot failure demonstrate the risks of deploying AI without proper delivery discipline, while Capital One's MLOps success shows the benefits of treating AI as part of established delivery pipelines. The emerging "Agentic Layer" concept addresses how AI agents interact with infrastructure while maintaining pipeline discipline and governance.
