Free tier usage monitoring in AWS - Mini Project: Build & Apply

Free tier usage monitoring

📖 Scenario: You have just started using AWS free tier services. To avoid unexpected charges, you want to monitor your usage of key AWS resources like EC2, S3, and Lambda.This project will help you create a simple script to track your free tier usage limits and current usage.

🎯 Goal: Build a script that stores AWS free tier usage limits, current usage data, calculates remaining free tier usage, and prints a summary report.

📋 What You'll Learn

Create a dictionary with AWS service names as keys and their free tier limits as values

Create a dictionary with current usage values for the same AWS services

Calculate the remaining free tier usage for each service

Print a clear summary showing service name, usage, limit, and remaining free tier

💡 Why This Matters

🌍 Real World

Monitoring free tier usage helps new AWS users avoid surprise bills by tracking how much of the free resources they have consumed.

💼 Career

DevOps engineers often build monitoring tools and alerts to manage cloud costs and resource usage efficiently.

1

Set up free tier limits data

Create a dictionary called free_tier_limits with these exact entries: 'EC2': 750, 'S3': 5000, 'Lambda': 1000000. These numbers represent the free tier limits for each service (hours for EC2, GB for S3, requests for Lambda).

AWS

# Create the free_tier_limits dictionary with exact entries
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with keys and values separated by colons.

2

Set up current usage data

Create a dictionary called current_usage with these exact entries: 'EC2': 300, 'S3': 1200, 'Lambda': 250000. These numbers represent your current usage for each service.

AWS

free_tier_limits = {'EC2': 750, 'S3': 5000, 'Lambda': 1000000}
# Create the current_usage dictionary with exact entries
# Your code here

Need a hint?

Use the same dictionary syntax as before but with your current usage numbers.

3

Calculate remaining free tier usage

Create a new dictionary called remaining_usage using a dictionary comprehension. For each service in free_tier_limits, subtract the current_usage value from the free tier limit to get the remaining usage.

AWS

free_tier_limits = {'EC2': 750, 'S3': 5000, 'Lambda': 1000000}
current_usage = {'EC2': 300, 'S3': 1200, 'Lambda': 250000}
# Create remaining_usage dictionary using dictionary comprehension
# Your code here

Need a hint?

Use a dictionary comprehension with {key: value for key in iterable} syntax.

4

Print usage summary report

Use a for loop with variables service to iterate over free_tier_limits. Inside the loop, print a line showing the service name, current usage, free tier limit, and remaining usage in this exact format: Service: EC2, Usage: 300, Limit: 750, Remaining: 450.

AWS

free_tier_limits = {'EC2': 750, 'S3': 5000, 'Lambda': 1000000}
current_usage = {'EC2': 300, 'S3': 1200, 'Lambda': 250000}
remaining_usage = {service: free_tier_limits[service] - current_usage[service] for service in free_tier_limits}
# Print the usage summary report
# Your code here

Need a hint?

Use an f-string inside the print statement to format the output exactly as shown.
