Best Practices

High Availability

StrategyImplementation
Multiple poolsSpread across server classes
Higher bidsReduce preemption risk
WebhooksMonitor and react to changes

Cost Optimization

StrategyImplementation
Right-size VMsChoose appropriate server class
Monitor bidsAdjust based on market
Scale downReduce count during off-hours

Data Safety

StrategyImplementation
External storageDon't rely on VM local storage
Regular backupsAutomate backup processes
Stateless designDesign for VM replacement

API & Terraform SOON

For programmatic VM management, use:

  • Spot Terraform Provider: Infrastructure as code
  • spotctl CLI: Command-line management
  • REST API: Direct API access

Troubleshooting

VM Not Accessible

Check:

  1. VM has an IP address assigned
  2. SSH key is correct - Manage SSH Keys
  3. VM status is "Online"

Unexpected Termination

Cause: Market price exceeded your bid.

Fix:

  1. Increase bid price
  2. Enable webhooks for alerts
  3. Design for preemption
