Patent attributes
Techniques are described for enabling resources within a cloud computing system to interact with each other. In certain embodiments, a token renewal mechanism is provided for extending the duration in which a first resource can access another resource. The token renewal mechanism can involve the first resource periodically causing a new credential to be generated for itself and then communicating the new credential to an identity and access management (IAM) system. The new credential may be generated for compliance with a credential rotation policy specifying that credentials should be changed after a certain period of time. The IAM system may associate a digital access token with the new credential so that for subsequent requests, the IAM system will only recognize the resource principal based upon the new credential. The digital token can be invalidated if a new credential is not changed within the specified period of time.
