FAQ
Questions teams ask before they adopt this workflow.
When should teams use AWS Cost Estimator Lite?
This tool is most useful when the team needs an answer they can carry into diagrams, documentation, and design reviews without rewriting the same context three times.
Who benefits most from AWS Cost Estimator Lite?
Architects, platform teams, and technical leads benefit most because they need explicit assumptions, clear review cues, and artifacts that survive implementation handoff.
How does AWS Cost Estimator Lite connect back to Architecto?
Architecto uses the free content surface as the top of a larger workflow. Once the team needs richer diagrams, schema visibility, change comparison, or technical documentation, the matching product module keeps the same decision context alive.
