Dealing with scale is a very important task in enterprise deployments. In the first section, we configured a Puppet master with puppetserver. We then expanded the configuration with load balancing and proxying techniques realizing that Puppet is simply a web service. Understanding how nodes request files, catalogs, and certificates allows you to modify the configurations and bypass or alleviate bottlenecks.

In the last section, we explored masterless configuration, wherein instead of checking into Puppet to retrieve new code, the nodes check out the code first and then run against it on a schedule.

Now that we have dealt with the load issue, we need to turn our attention to managing the modules to be applied to nodes. We will cover the organization of the nodes in the next chapter.
