This Terraform script automates the provisioning of an EC2 instance and a Lambda function that starts and stops the instance at specific times.

• Terraform installed on your local machine. You can download it here.
• An AWS account with appropriate permissions to create EC2 instances, Lambda functions, and IAM roles.

1. Generate an SSH key pair using the ssh-keygen command:

   ssh-keygen -t rsa

   Follow the prompts to choose a location and passphrase. Your private key (keyname.pem) will be saved in ~/.ssh/.

2. Update the Terraform configuration with your SSH key name:

   Open modules/ec2/main.tf and replace YOUR_KEY_NAME with the name of your SSH key (without the .pem extension).

3. Initialize Terraform and apply the configuration:

   cd lambda-function
   terraform init
   terraform plan
   terraform apply

   Review the plan and confirm the changes to deploy the EC2 instance and Lambda function.

• modules/lambda/main.tf: Contains the Terraform configuration for provisioning the EC2 instance and Lambda function.
• modules/lambda/start.zip: Lambda function code to start the EC2 instance.
• modules/lambda/stop.zip: Lambda function code to stop the EC2 instance.

The Lambda function is scheduled to run at specific times using Amazon EventBridge (formerly CloudWatch Events). By default, it starts the EC2 instance at 8:00 AM UTC and stops it at 8:00 PM UTC. You can adjust the schedule expressions in modules/lambdamain.tf as needed.
