This script provides a pricing and capacity summary of EBS volumes in a specified region. The script is also capable of recognising unused EBS volumes, print their utilisation and costs.
The script fetches all EBS volumes in specified region counts them into categories based on EBS type. Then the script fetches current EBS prices from AWS Pricing API for specified region and calculates EBS monthly expenditures.

- argparse
- json
This is the help output from the script.
$ ./price_of_ebs.py --help
usage: price_of_ebs.py [-h] [-p PROFILE] [-i AWS_ID] [-k AWS_SECRET_KEY] [-v]
aws_region
Calculate price of EBS volumes in given region
positional arguments:
aws_region aws region code e.g. "us-east-1"
optional arguments:
-h, --help show this help message and exit
-p PROFILE, --profile PROFILE
aws profile to use, "default" profile is used if not
specified
-i AWS_ID, --aws-id AWS_ID
aws access key id to use
-k AWS_SECRET_KEY, --aws-secret-key AWS_SECRET_KEY
aws secret access key to use
-v, --verbose display verbose output including pricing for each
storage type
The script is able to utilise multiple authentication methods, first using profiles from ~/.aws/credentials (preffered) and second using direct credentials as arguments to the script (not preffered). Third method will be using environmental variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY this will not be preffered also.
Using the script in non-verbose mode with default profile.
$ ./price_of_ebs.py eu-west-1
total: $247
Using the script in verbose mode with different AWS profile.
$ ./price_of_ebs.py --verbose --profile ebs_user eu-west-1

- Addition of another authentication method using environmental variables
AWS_ACCESS_KEY_IDandAWS_SECRET_ACCESS_KEY. - Addition of new options that could calculate daily, weekly and anual expenditures. Now the script only monthly by default. This could be specified with
-yor--year,-wor--weekand so on.
