"Running at Scale: Practical Performance Tuning with Puppet" by Sam Kottler Engineer, Red Hat.
Presentation Overview: This session will talk about some production issues I've seen running Puppet in large environments. From how to manage a single master with hundreds of hosts to real-life patterns for building high availability clusters that scale to 10's of thousands of agents. Another important topic that will be covered is how to deploy networked filesystems that perform well under high load and streaming files to many hosts simultaneously.
