Abstract: Systems and methods for correlating services are described. For one embodiment, a number of cloud environments located in different regions to provide a platform-based single sign-on (SSO), with each cloud environment hosting a same set of cloud services. A unique identifier (ID) can be created for a user based on a profile of the user. The unique ID can be used to correlate the cloud services within each cloud environment and across the cloud environments in the different regions. The unique ID can be used to download the user's preference data to a vehicle that the user is to drive in each of the regions so that the user can drive the vehicle with a set of desired driving settings and infotainment applications. The unique ID of a user and preference data of the user can be anonymized using one or more security protocols.
