2024 Regional Skills Competition Cloud Computing Task 1

April Fool's Day 🤪

This does not cover actual methods. It was written to experiment how much traffic certain search terms get from Google searches.

AWS CloudFormation Script

1. Script Summary

This script uses AWS CloudFormation to automatically configure the following functions:

• Creating an Empty Resource Stack: The EmptyResource section references the empty-template.yaml template to create an empty stack. Although there are no actual resources, it's useful for defining stack structure and dependencies.
• Message Output: The EchoResource section calls the Lambda function my-echo-function to output the message "Hello, world!".
• Providing Output Values: The Outputs section provides EmptyOutput (empty string) and EchoOutput (Lambda function output message) values.

2. How to Use the Script

1. Save Template File:
   • Save the empty-template.yaml file to an S3 bucket.
   • Save this script file to your desired location.
2. Create CloudFormation Stack:
   • Use the AWS Console or CLI to create a CloudFormation stack referencing the script file.
   • When creating the stack, you must enter the my-echo-function Lambda function ARN in the ServiceToken property of the EchoResource section.
3. Check Output:
   • After stack creation is complete, check the EmptyOutput and EchoOutput values in the Outputs section.

3. Additional Features and Applications

3.1. Adding Resources:

This script is a basic example, and you can expand the automatic configuration by adding various resources to fit your actual environment. For example, you can add the following resources:

• EC2 instance creation and configuration
• RDS database creation and configuration
• S3 bucket creation and configuration
• CloudFront distribution setup
• Lambda function creation and configuration

3.2. Adding Parameters and Conditions:

You can add parameters to the script to receive user input values during stack creation and dynamically change configurations. You can also use conditional statements to adjust

configurations according to the environment.

3.3. Deployment Automation:

You can use AWS CodePipeline, CodeBuild, etc. to automate script updates and deployment.

3.4. Modularization and Reuse:

You can modularize scripts to increase code reusability and easily adjust for various environments.
