Financial resource ownership
As we reviewed in Chapter 1, Cloud Architecture and Navigation, cloud services operate on the Shared Responsibility Model. Understanding this becomes increasingly important as you begin to assess change management controls, which is the ability to log and view changes in a cloud environment and protect against unexpected costs. In most scenarios, it is not the responsibility of the cloud provider to prevent an organization from occurring overages because they have consumed more resources than planned or because there is a lack of controls around who can request increased quota and services. An organization must be vigilant in establishing and communicating a financial ownership and responsibility structure, with both process and technical controls that enforce that structure.
