Puppet uses a declarative language (Puppet DSL) to describe the desired state of infrastructure.

Supports agent/master and agentless (Puppet Bolt) modes for managing nodes.

Ensures consistency across servers by automatically enforcing configurations.

Integrates with cloud providers, virtualization, and container platforms.

Widely used in enterprise IT and DevOps for automated provisioning and compliance.

Puppet is a declarative configuration management tool for consistent infrastructure automation.

Supports agent-based and agentless operations with reusable modules and manifests.

Idempotence ensures repeatable and safe configuration enforcement.

Used widely in enterprise IT and DevOps pipelines for compliance and scalability.

Strong community, extensive modules, and enterprise support make Puppet reliable for production.

Is Puppet agent mandatory? -> No, Bolt allows agentless execution.

Can Puppet manage cloud infrastructure? -> Yes, via providers and modules.

Is Puppet declarative or imperative? -> Declarative.

Does Puppet scale to thousands of nodes? -> Yes, especially Puppet Enterprise.

Can Puppet enforce compliance? -> Yes, automatically reports and remediates state.
