Start/Stop Instances with Lambda AWS Across All Regions

We want reduce costs in our AWS account. We will use the following hours:

Starting at Morning --> 05:10:00 GMT

Shutdown At Night --> 20:10:00 GMT

You can modify all content in lambda.tf file. Your boss Finance will appreciate it ;-)

Technologies we’ll use:

• EC2 (compute instances)
• Lambda (compute service that lets you run code without worrying about servers)
• CloudWatch (monitoring service for AWS)
• Finally IAM (Identity and Access Management, control security access)

apt-get install terraform (Google)

• Terraform Version == v0.11.3
• S.O == Ubuntu Xenial 16.04.4 LTS

Steps before deploy:

1º Tag your instance/instances

Status save_money

2º Create your ZIP

terraform apply --target data.archive_file.cost_savings_zip

Deploy:

terraform plan
terraform apply

Testing

If everything is working well, we will see CloudWatch :
