Our review
Pros	Raft replication supports strong consistency across cluster members. Transactions, watches, leases, and historical revisions support dynamic configuration. Snapshots and cluster recovery provide tools for restoring cluster data.	Scheduled desired-state enforcement with cron and rate expressions Patch, software, agent, and script management across supported nodes Compliance reporting with versioned JSON/YAML SSM documents

Its gRPC and HTTP/JSON interfaces may not fit teams seeking other protocols.	Agent-based cloud deployment requires Systems Manager-managed nodes Focused on infrastructure configuration rather than application settings Associated AWS services and resources may incur separate charges
