Spot Instances and Cost-Efficient Compute
Learn how to use EC2 Spot Instances and mixed instance fleets to dramatically reduce compute costs while handling interruptions gracefully.
What Are Spot Instances?
Spot Instances let you use spare EC2 capacity at discounts of up to 90% versus On-Demand pricing.
The catch: AWS can reclaim them with a short warning when it needs the capacity back.
On-Demand vs Reserved vs Spot
Three pricing models:
- On-Demand — pay per second, no commitment, full price
- Reserved / Savings Plans — commit for 1-3 years, big discount
- Spot — cheapest, but interruptible
