All components of the COTAK system are deployed in the Amazon Web Services (AWS) GovCloud, which is designed to host sensitive data, regulated workloads, and address the most stringent U.S. government security and compliance requirements. In addition to providing high security, operating COTAK in this way reduces the risk of hardware failures, power outages, or other technical faults disrupting the system. The cloud computing system used by COTAK is maintained by State employees and vetted contractors.
