Cloud Architecture

Cloud architecture in a regulated environment is a scoping decision before it is an engineering one. The boundary you draw determines the control count, the evidence you owe, and what an assessor is entitled to inspect. Draw it wide and you inherit controls for systems that never touch regulated data. Draw it badly and you find out during assessment.

We build multi-account landing zones codified in Terraform, with network segmentation, explicit egress deny, KMS key policies that carry no wildcard principals, and IAM trust policies scoped to the exact role that may assume into the data plane. The result is reproducible across environments, reviewable in a pull request, and diffable when an assessor asks what changed. The discipline is the same under every framework. What differs is where the boundary falls and how many controls sit inside it.
