Network management of cloud computing environments subject to different data control policies is standardized in a manner that ensures compliance with the data control policies. Executions services and source of truth services are located in a remote cloud computing environment separate from the cloud computing environments being managed. The execution services implement workflows to manage different aspects of the cloud computing environments, including monitoring, incident management, deployment, and buildout. The source of truth services provide network configuration information for the cloud computing environments to allow automated operation of the execution services. The execution services issue requests for management operations to device access services in the cloud computing environments. In response to the requests, the device access services obtain access control data to access the network devices and perform the management operations.
