Infrastructure teams
Use it when deployment control, auditability, and portability are primary requirements.
Skip if the team cannot own patching, monitoring, and incident response.
DevOps engineers
Consider it when automation and configuration can be reviewed and integrated into existing runbooks.
Skip if the project lacks a tested upgrade or rollback path.
Self-hosting teams
Evaluate it when running the service in your environment is a deliberate ownership decision.
Skip if a zero-operations SaaS experience is non-negotiable.
