1. Resource Abstraction Layer: Puppet abstracts system resources into a powerful, yet simple, declarative language. For example, you can describe a package resource in Puppet like this:
package { ‘nginx’:
ensure => installed
}
2. Automation: Puppet automates the process of configuring and managing systems, making it easier to keep track of changes and ensure consistency across different machines. For example, you can use Puppet to automatically install and configure a web server.
3. Security: Puppet helps secure systems by enforcing access control and providing a single source of truth for configuration data. For example, you can use Puppet to ensure that only certain users have access to certain files.
4. Scalability: Puppet can be used to manage thousands of machines, all from a single machine. For example, you can use Puppet to deploy a web application to hundreds of servers at once.
5. Extensibility: Puppet is highly extensible, allowing users to write custom functions and modules to extend its functionality. For example, you can write a custom module to deploy a web application to multiple servers.
