Adoption changes the control boundary
Cloud adoption distributes responsibilities across business owners, platform teams, application teams and providers. The important question is whether those responsibilities are understood and demonstrable.
Start with ownership
For each critical workload, record who owns identity, configuration, data, monitoring, recovery and exceptions. Shared responsibility only becomes useful when it is mapped to real roles and operating routines.
Use evidence to guide priorities
A control baseline should distinguish a missing control from missing evidence. Both need attention, but they may require different actions, owners and investment decisions.
