Jesus Nunez presented on using Puppet in a decentralized, masterless architecture. In a masterless configuration, each node pulls Puppet code and modules from a central Git repository and compiles its own catalog without a master server. A remote executor is used to trigger Puppet runs on nodes by updating code via Librarian Puppet, generating Puppet and ENC files, and running Puppet apply commands. This allows distributed processing without a single point of failure compared to a traditional master-node architecture.
