Abstract
A method is implemented by one or more network devices to identify an originating point of failure in a composite service executed in a cloud computing environment. The execution of the composite service includes execution of a plurality of atomic services in an ordered sequence, where for each atomic service that is executed, an execution trace for that atomic service is stored in a blockchain to form an ordered sequence of execution traces, where the execution trace for a given atomic service is signed using the private key associated with that atomic service and analyzing one or more of the ordered sequence of execution traces to determine which of the plurality of atomic services originated the failure, where each execution trace that is analyzed is authenticated using the public key that corresponds to the private key associated with the atomic service that generated that execution trace.
