Compute Savings: Reserved Instances & Savings Plans

FinOps for Scalable Infrastructure

Commitment pays off

If you know you'll use a server for a year, don't pay hourly prices.

RI vs Savings Plans

  • Reserved Instances (RI): Specific to a type/region.
  • Savings Plans: More flexible (apply across instance families).

The Calculation

We'll use a spreadsheet to calculate the break-even point. If you commit to 1 year, you can save ~30-60%.
