Spot Price Compare

This script was developed to help you to compare the Spot Price between instances types and which the actual saving percentage (more information about spot click here).

Prerequisites

You need this things to run the script:

• AWS Account
• aws-cli
• AWS Credentials
• Python
• Pip
• Git

And install the modules with pip:

pip install -r requirements.txt

Usage

To use this script you need to pass some information, example:

python spot-price.py --region us-east-1 --instance-type m5.xlarge --product-type Linux/UNIX --output text --price-type all --mode compare

The outputs can be:

Text

--- best economy price ---
instance type: m5.xlarge
region: US East (N. Virginia)
zone: us-east-1f
vCPU: 4
ecu: 16
memory: 16.0
OnDemand price: 0.192
Spot price: 0.0734
economy: 61.77 %

--- best memory price ---
instance type: m5.xlarge
region: US East (N. Virginia)
zone: us-east-1f
vCPU: 4
ecu: 16
memory: 16.0
OnDemand price: 0.192
Spot price: 0.0734
economy: 61.77 %

--- best ecu price ---
instance type: m5.xlarge
region: US East (N. Virginia)
zone: us-east-1f
vCPU: 4

Interface

usage:
  $ spot-price.py -h
  $ spot-price.py --region us-east-1 --instance-type m5.xlarge --product-type Linux/UNIX --output text --price-type all --mode compare
  $ python spot-price.py --region us-east-1 --instance-type m5.xlarge c5.xlarge --product-type Linux/UNIX --output json --price-type all --mode show

Compare the Instance's actual price and spot price.

optional arguments:
  -h, --help            show this help message and exit
  --region REGION       Region's code, like us-east-1
  --product-type {Linux/UNIX,SUSE Linux,Windows,Linux/UNIX (Amazon VPC),SUSE Linux (Amazon VPC),Windows (Amazon VPC)}
                        (default: Linux/UNIX)
  --mode {show,compare}
                        (default: show)
  --output {text,json,table}
                        (default: text)
  --price-type {all,ecu,memory,economy}
                        (default: all)
  --instance-type INSTANCE_TYPE [INSTANCE_TYPE ...]
                        (t1.micro or t1.micro t2.micro ...)
