AWS Systems Manager State Manager vs config.XO

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.

config.XO extends Microsoft PowerShell Desired State Configuration to manage Windows and Linux node configurations. It evaluates managed servers and clients against their intended state and corrects drift automatically. Teams can assign configurations to groups or individual hosts, create their own configurations and modules, or use a web wizard to build DSC configurations without writing code. It supports on-premises physical hosts and virtual machines, as well as internet-connected public-cloud virtual machines; proxy configuration is possible. Listed Windows versions are Server 2022, 2019 and 2016, plus Windows 11 and 10. Configuration runs can install packages through application.XO. The cloud service is agent-based and lists patch management, policy as code and compliance reporting alongside drift detection. Uploaded DSC configurations are encrypted with an XOAP-provided certificate, but user-uploaded compiled MOF files are not encrypted. XOAP says its service is hosted in Europe, is GDPR compliant, encrypts management connections and does not store actual user credentials. Free includes three managed systems; Standard is €449.00 per month or €4,999 billed annually.
