Quizplus · Accepted Answer

Under the Federal Rules of Civil Procedure, data custodians are assumed and expected to have full and comprehensive knowledge of the internal design and architecture of their systems. In a cloud environment, especially with PaaS and SaaS, it is impossible for the data custodian to have this knowledge because those systems are controlled by the cloud provider and protected as proprietary knowledge.
