Cloud Cost Pricing Extract Utility

Used to create azure.json and aws.json pricing files using AWS and Azure pricing APIs (and additional magic).

Prereqs

This script assumes:

• You already have been granted access to pricing data in both Azure and AWS
• AWS cli is configured locally
• You have Azure credentials you can provide in the .cloudcost config file.

Installation

Simply clone the repo to run this standalone. Calling it like this will collect both AWS and Azure pricing files to the users home directory. Use --help to get options or see below.

bundle install
bundle exec cloudcost

Usage

The options are basic.

bundle exec cloudcost --help 
Options:
  -o, --output=<s>           Output Directory (default: .)
  -a, --azure, --no-azure    Get Azure Pricing (default: true)
  -w, --aws, --no-aws        Get AWS Pricing (default: true)
  -h, --help                 Show this message

Pricing File Formats (AWS and Azure)

The AWS price file is caputred as-is and will remain intact. It is not modified any way.

The Azure SKU and pricing data file from MS is merged together via this gem to more closely resemble the way the AWS pricing file is structured. It is an array of product hashes.

Each product hash in the array has the capabilties or characteristics of a compute or disk product and attached is a list of product terms. The systems can then besearched by the characteristics (CPU, Memory) and the pricing terms are associated.

Run the script and review a formated version of the aws.json and azure.json files outputed by this code to get more familiar with the contents.

Once you see the files live the data will make more sense.

Azure and AWS Authentication

It's important to understand that this utility REQUIRES that vendor access and authentication are already configured and functioning on the local system.

Azure

The authentication for Azure is pulled from a local config file in $HOME. See the sample in configs for the format. The utility will put a sample file in $HOME/.cloudcost.sample the first time executed if it's .cloudcost is not found. That can be copied into place: cp .cloudcost.sampe .cloudcost

AWS

AWS requires that the local user that is running the script have the $HOME/.aws configurations in place. Commands, like the following, should produce valid AWS repsonses from the system you intend to run this script.

aws ec2 describe-instances
aws s3 ls
