Last updated Aug 17, 2023 Edit Source

On-Demand is a Pay-As-You-Go (PAYG) model, where you consume compute and then you pay.

When you launch an EC2 instance it is by default using  On-Demand Pricing

• On-Demand has *no up-front payment and no long-term commitment
• You are charged by the hour or by the minute (varies based on EC2 Instance Types
  • per-second for:
    • Linux, Windows, Windows with SQL Enterprise, Windows with SQL Standard, and Windows with SQL Web Instances that do not have a separate hourly charge
  • per-hour:
    • full hour for all other instance types.
• When looking up pricing it will always show EC2 pricing is the hourly rate
  • On-Demand is for applications where the workload is for short-term, spikey, or unpredictable.
  • Used for when you have a new app for development or you want to run an experiment
