Also, simpler answer than I already gave: “elastic” and “scalable” X don’t imply a lack of committed resources, but rather just a control plane that auto-scales

Also, simpler answer than I already gave: “elastic” and “scalable” X don’t imply a lack of committed resources, but rather just a control plane that auto-scales your commitment to ensure that you’ve always got more than you need. E.g. AWS Elastic File Store: an auto-resizing NAS-like abstraction, but at any given point, a committed size where you’re paying for unused space. Vs. Amazon S3 (which might as well stand for “serverless storage service”) — where you only pay for what you use, with no committed capacity beyond current usage.
