The Biggest Foot Gun In Cloud Cost Control: Giving Developers Access To AWS Billing Information

The biggest foot gun in cloud cost control is not giving your developers access to AWS billing information. Without this essential feedback loop, they can’t see the cost impact of their decisions and will keep making expensive choices unknowingly. Give them access to AWS billing, teach them how to use it, and watch your cloud costs become more sustainable.

You Should Know:

1. AWS Billing Access:

Grant developers access to AWS Billing and Cost Management Console.
Use IAM policies to provide granular access to billing information.

{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"aws-portal:ViewBilling",
"aws-portal:ViewUsage"
],
"Resource": "*"
}
]
}

2. AWS Cost Explorer:

Enable AWS Cost Explorer to visualize and manage your AWS costs and usage.
Use the following command to enable Cost Explorer:

aws ce get-cost-and-usage \
--time-period Start=2023-10-01,End=2023-10-31 \
--granularity MONTHLY \
--metrics "UnblendedCost" "UsageQuantity"

3. AWS Budgets:

Set up AWS Budgets to track your costs and usage.
Create a budget with the following command:

aws budgets create-budget \
--account-id 123456789012 \
--budget file://budget.json \
--notifications-with-subscribers file://notifications.json

4. AWS Cost Anomaly Detection:

Use AWS Cost Anomaly Detection to monitor and alert on unusual spending.
Set up anomaly detection with:

aws ce create-anomaly-monitor \
--anomaly-monitor-name "MonthlyCostMonitor" \
--monitor-type "DIMENSIONAL" \
--monitor-dimension "SERVICE"

5. AWS Cost and Usage Report (CUR):

Generate detailed reports on your AWS usage and costs.
Enable CUR with:

aws cur put-report-definition \
--report-definition file://report-definition.json

6. AWS Trusted Advisor:

Use AWS Trusted Advisor to get real-time guidance to help you provision your resources following AWS best practices.
Check cost optimization recommendations:

aws support describe-trusted-advisor-checks --language en

7. AWS Lambda for Cost Optimization:

Automate cost optimization tasks using AWS Lambda.
Example Lambda function to stop EC2 instances during non-business hours:

import boto3

def lambda_handler(event, context):
ec2 = boto3.client('ec2')
instances = ec2.describe_instances(Filters=[{'Name': 'instance-state-name', 'Values': ['running']}])
for reservation in instances['Reservations']:
for instance in reservation['Instances']:
ec2.stop_instances(InstanceIds=[instance['InstanceId']])
return {
'statusCode': 200,
'body': 'Stopped instances successfully'
}

What Undercode Say:

Cloud cost management is a critical aspect of modern IT infrastructure. By providing developers with access to AWS billing information, organizations can foster a culture of cost-awareness and accountability. Utilizing tools like AWS Cost Explorer, Budgets, and Cost Anomaly Detection can help teams monitor and optimize their cloud spending effectively. Automating cost optimization tasks with AWS Lambda and leveraging AWS Trusted Advisor for best practices can further enhance cost efficiency. Remember, sustainable cloud spending is a team effort, and embedding cost awareness at every stage of the development lifecycle is key to achieving long-term financial health in the cloud.
