Hi Sudharma, Electing one master that is able to deploy is the right approach. Since the metadata of a deployment is written to the database and the database is shared among all nodes, sending notifications is not necessary. This is all under the assumption that all nodes share the same deployment folder, e.g. using SMB or NFS.
