When people talk about monitoring generally they are system people talking of hosts and network gear going up and down. That is the monitoring world as most people know it and it must change if we want to write better applications and offer better services.
After a brief presentation of configuration management (CM) basics, we'll start with an ill-fated tale from the recent past about disaster recovery (also known as a case study, if you must): how our CM saved us, how it didn't, and what could have been done better. This could lead to a discussion about best practices around beers after the session.
We use Cfengine 3, and will introduce the software, overview the main differences with other open source CM tools before explaining why we like this choice. But Cfengine is not all: what enables us to manage our configuration completely are the practices and tools we've built around it. We will describe these in detail, probably offering a live demo (if Murphy permits).
