Spot Optimization

Core services ✓ → Projects

Projects · 2 — Deploy · ~10 min · AWS — AI, Performance & Cost

What is this?

Spot optimization maximizes discount while minimizing interruption using diversified pools, capacity-optimized allocation, and checkpointing.

Why should you care?

AwsVerse render farm and ETL use Spot with On-Demand fallback for cost-efficient batch.

See it live — copy this example

Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).

aws ec2 create-launch-template \
  --launch-template-name awsverse-spot-mixed \
  --launch-template-data '{"InstanceMarketOptions":{"MarketType":"spot","SpotOptions":{"MaxPrice":"0.05","SpotInstanceType":"one-time"}},"InstanceType":"t3.medium","ImageId":"ami-0abc"}'

What happened?

Launch template requests Spot at max $0.05/hr.
ASG mixed instances policy blends Spot and On-Demand percentages.

Practice next

Identify fault-tolerant workload.
Create ASG with 70% Spot capacity-optimized.
Handle Instance Interruption Warning in app.
Add Spot Fleet with multiple instance types.
Use Spot placement score API before launch.

Remember

Diversify Spot pools. Capacity-optimized reduces interruptions. Checkpoint long jobs.

AwsVerse ETL Spot mix

Nightly job tolerates 2-min interruption.

Outcome: Mixed ASG saves 65% with 99.2% completion on first run.
