EC2 Nightly Automated Shutdown

Overview

This project automates the nightly shutdown of EC2 instances using AWS Lambda and EventBridge, all provisioned with Terraform. The system is designed to:

• Trigger: An EventBridge rule is scheduled to trigger every day at a specific time (e.g., 10 PM).
• Lambda Function: The triggered EventBridge rule invokes a Lambda function.
• EC2 Instance Shutdown: The Lambda function utilizes the AWS SDK for Python (Boto3) to stop the specified EC2 instances.

Prerequisites

• An AWS account with necessary permissions.
• Terraform installed and configured.
• Basic understanding of AWS services (EC2, Lambda, EventBridge, IAM).

Terraform Configuration

The Terraform configuration defines the following resources:

• IAM Role: Grants the Lambda function permission to stop EC2 instances.
• Lambda Function: Contains the Python code to stop the EC2 instances.
• EventBridge Rule: Schedules the Lambda function to trigger daily.
• EC2 Instances: The instances to be shut down.
