Abstract

Systems management activities have had a huge step forward with Configuration management tools like Puppet. Puppet code is usually contained in modules that manage installation and configuration of applications. This presentation shows an approach to Puppet modules design that tries to face different facets of Puppet programming:
 A coherent set of class parameters to manage common functions (standard API)
 Separate custom code from core modules
 Integrated and automated monitoring and firewalling functions
 Use Puppet not only to configure but also to provide information from the managed hosts
 Provide via Puppet the information needed to manage applications deployments.
