描述

The tool is set to launch servers in the On-Demand way, meaning this is the most expensive way to go about it. This should be changed such that users can introduce the use of Spot instances to save on costs, or even take advantage of Reserved Instances if they have RI capacity already set aside. I'm unfamiliar how the latter works when used with CFN stacks, so this will require additional research.

研究方向
Review the existing code for launching EC2 instances, likely in a Python script that generates CloudFormation templates. Identify where instance type and purchase option are defined. For Spot Instances, modify the code to allow users to specify Spot price and allocation strategy. For Reserved Instances, research how to incorporate them into CloudFormation stacks, as this may require additional AWS API calls. The issue mentions that the tool currently only supports On Demand instances, so the goal is to add alternative purchase options.
