Puppet can be used as a control panel to perform a wide variety of tasks within your infrastructure. It can be used to trigger failover between hot standby servers or entire data centres. It can be used to deploy package updates across large clusters. It can be used to deploy code to staging and then onto production, ensuring the right versions are present. It can be used to replicate production environments locally for all our engineers. And it can even be used for config management!
This talk will take a hands on technical look at how we use Puppet to achieve all these things. It will include code samples, hints and tips and explain how the flexibility of Puppet can be used to really control your entire infrastructure.
This talk was given by David Mytton at PuppetCamp 2013: Berlin, London and Munich.
