AWS Systems Manager State Manager vs Puppet

AWS Systems Manager State Manager automates keeping managed nodes and other AWS resources in a state that customers define. Its associations specify the configuration to maintain, when to apply it and which resources to target. Targets can be selected by tags, AWS Resource Groups, individual node IDs or all managed nodes in the current Region and account. Associations can run immediately or later and accept most standard cron and rate expressions, but association cron expressions cannot specify months. On Linux, macOS and Windows Server managed nodes, State Manager can bootstrap software, schedule agent updates, configure network settings, join nodes to a Microsoft Active Directory domain and run scripts. Association run output can be stored in Amazon S3, and State Manager is supported as an event type and target type in Amazon EventBridge rules. It has no additional charge, although limits may apply. State Manager runs as a cloud service with an agent-based model. AWS Systems Manager follows a shared responsibility model: AWS protects cloud infrastructure, while customer responsibilities depend on the service, data and requirements. Third-party auditors assess Systems Manager under assurance programs including SOC, PCI, FedRAMP and HIPAA.

Puppet Enterprise provides policy-driven configuration management and infrastructure automation for complex cloud and hybrid environments. It uses policy as code to continuously enforce desired state, helping organizations identify and remediate configuration drift. Both agent-based and agentless management are supported, with a web interface and role-based access control. Puppet Enterprise Advanced adds continuous enforcement of CIS Benchmarks and DISA STIGs, self-service automation, AI features, observability integrations, and advanced patching. It also integrates with third-party vulnerability scanners, including Nessus, for remediation. Listed integrations include GitHub, AWS, Microsoft Azure, Google Cloud Platform, HashiCorp Vault, and ServiceNow. Agents are listed for Linux, Windows, and macOS. Puppet describes the product as suited to medium and large organizations managing complex environments that require security, compliance, and centralized automation. Pricing is custom; a free trial runs on up to 10 nodes with no commitment or time limit. Network and edge device management is optional, and licensing for those devices requires contacting sales.
