Puppet Enterprise is IT automation software that gives system administrators the power to easily automate repetitive tasks, quickly deploy critical applications, and proactively manage infrastructure, on-premises or in the cloud.
Puppet Enterprise automates tasks at any stage of the IT infrastructure lifecycle, including: discovery, provisioning, OS and app configuration management, orchestration, and reporting.
Understanding Resources is fundamental to understanding how Puppet works. Resources are like building blocks (think Lego). They can be combined to model the expected state of the systems you manage.
Classes define a collection of resources that are managed together as a single unit. You can also think of them as named blocks of Puppet code, which are created in one place and invoked elsewhere.
Autoloading in Puppet means that your modules will be loaded by Puppet at compile time, as long as they follow a predictable structure. This course will help you with the basics of Autoloading.
Facter is Puppet’s cross-platform system profiling library. It discovers and reports per-node facts, which are available in your Puppet manifests as variables.
The Event Inspector, part of the Puppet Enterprise Console, is a reporting tool that provides data for investigating the current state of your infrastructure. Its focus is on correlating information and presenting it from multiple perspectives in order to reveal common causes behind related events.
The order of resources in a Puppet manifest does not matter. Puppet assumes that most resources are not related to each other and will manage the resources in whatever order is most efficient.
Your entire datacenter, from the network to the applications, depends on consistent time for many different functions, such as security services, certificate validation, and file sharing across nodes.
