竞价实例的出价低于当前竞价市场价格，导致AWS回收该实例。

解决方案

  1. Use a Spot Fleet or EC2 Fleet with multiple instance types and bid prices. Example: `aws ec2 request-spot-fleet --spot-fleet-request-config file://config.json` where config.json includes diverse instance types (e.g., m5.large, c5.large) and a max bid equal to the On-Demand price. This increases chances of capacity availability.
  2. Implement graceful shutdown handling. Use the EC2 metadata endpoint to check for termination notices (http://169.254.169.254/latest/meta-data/spot/termination-time) and save state before termination. Example script: `curl http://169.254.169.254/latest/meta-data/spot/termination-time 2>/dev/null && echo "Termination imminent"`

无效尝试

常见但无效的做法:

  1. Increase the bid price to the On-Demand price 60% 失败

    Setting bid to On-Demand price defeats the purpose of Spot Instances and may still not guarantee persistence during high demand. AWS may still terminate if capacity is reclaimed.

  2. Use a different instance type without changing bid 70% 失败

    Different instance types have different Spot markets; the same bid may still be too low for the new type.
