How It Works
Cloud providers charge for compute, storage, and networking resources at a published per-second or per-hour rate. You provision a resource, use it, and pay only for the time it runs. AWS calls this on-demand pricing. Azure and GCP use the same model under the same name. Rates are set by the provider and can change over time, but within a billing period you pay the rate in effect at the time of use. There are no contracts, no minimums, and no penalties for stopping.
Why It Matters for Cloud Cost
Dynamic pricing gives engineering teams maximum flexibility: spin up a server, run a job, shut it down, and pay only for what ran. That flexibility comes at a cost. On-demand rates are the highest rates a provider publishes. Teams that run workloads continuously at on-demand prices leave significant savings on the table compared to committing to Reserved Instances, Savings Plans, or Committed Use Discounts. Without a strategy to move stable workloads off dynamic pricing, cloud bills scale linearly with usage rather than bending downward as the business grows.
Usage AI’s Autopilot mode automatically purchases and adjusts commitment instruments across AWS, Azure, and GCP daily, moving stable workloads off on-demand rates without requiring any infrastructure changes.
