How to terminate persistant spot 请求?

AWS学习笔记3 -- Spot Instance， Spot fleets _Spot instance

Spot Fleets

  • Spot instances + (optional) On-Demand Instances
  • 在价格约束下满足目标产能 meet the target capacity with  price constraints
  • 定义possible launch pools: instance type (m5.large), OS, AZ
  • 可以有多个launch pools, 供fleet选择
  • 当满足产能，或达到最高费用时停止launch instances
  • Strategies to allocate spot instances:
  • 最低价格 lowest price：from the pool with the lowest price (cost optimization, short workload)
  • 多元化 diversified: distributed across all pools (great for availability, long workloads)
  • 容量优化 capacity optimized: pool with the optimal capacity for the numer of instances


Spot Fleets allow us to automatically request Spot Instances with the lowest price
