Techniques for facilitating usage tracking in hybrid cloud computing systems are disclosed herein. In one embodiment, a method can include receiving, from a private cloud computing system, a request for uploading usage data to a storage in a public cloud computing system. The method can also include authenticating the received request based on a service subscription of the private cloud computing system, and upon authentication, providing the private cloud computing system with an access permission to store the usage data in the storage of the computing system. The method can further include receiving the usage data from the private cloud computing system submitted with the access permission and storing the received usage data in the storage of the public cloud computing system.
