Build for Consumability, The Provider to Consumer Model That Makes AWS Scale.

Most platform teams think their job is to build infrastructure. They're wrong. Their job is to build infrastructure that other teams can consume without thinking about it. The difference matters more than most organisations realise. A platform team that builds a beautifully architected AWS landing zone but makes it painful to consume has built a bottleneck, not a platform. And in a large enterprise (where dozens of product teams need to ship features against real deadlines) bottlenecks don't just slow you down, they breed shadow IT, workaround architectures, and the kind of ungoverned sprawl that keeps security teams awake at night. The Provider to Consumer model fixes this. It's a shared responsibility framework that gives the platform team (the Provider) clear ownership of foundational infrastructure, while giving product teams (the Consumers) a fast, governed path to build and deploy. Neither side operates in isolation. Both sides have accountabilities, and the interfaces between th
