For two decades, hyperscalers have claimed that using modern cloud services requires moving all your data into their datacenters, subjecting it to foreign jurisdictions like the US CLOUD Act.

This talk challenges that assumption. We show how cloud-native technologies enable managed cloud services to be delivered where the data already lives: on-premises, in a private cloud, or with trusted public providers.

Using Kubernetes and CNCF projects such as Crossplane, Prometheus, and Grafana, we present a platform model where databases, queues, caches, and DevOps tools are delivered as self-service managed services without data relocation or provider lock-in. Data sovereignty, we argue, is not a contract; it’s an architectural decision.
