Claim 17:
18. A computer implemented method, comprising:
determining, on each node in a set of selected nodes in a distributed computing system, whether a computing system configuration C is valid;
if the computing system configuration C is valid on each of the selected nodes, then signing the computing system configuration C with each of the selected nodes; and
controlling deployment of the computing system configuration C to a subsequent node based on whether the computing system configuration C is validly signed by the set of selected nodes, wherein controlling deployment of the computing system configuration C comprises:
receiving the configuration and signatures on the computing system configuration C;
obtaining a public key for each node in the set of selected nodes; and

running a signature validation algorithm based on the obtained public keys, the computing system configuration C, and the signatures.
