Abstract: Example implementations relate to communication in a federated computing environment. For example, a method includes identifying, by a computing resource, at least one other computing resource within the federated computing environment, where the federated computing environment includes a pool of computing resources. The method also includes exchanging trust parameters with each of the at least one other computing resource, where the trust parameters are indicative of identification and authenticity of computing resources within the pool of computing resources. The method also includes communicating a first set of tokens to each of the at least one other computing resource, and receiving a second set of tokens from the at least one other computing resource, such that the first set of tokens and the second set of tokens form a global set of tokens for accessing the pool of computing resources of the federated computing environment.
