# stop_start_instances
## Automate the stop & start of EC2 instances to optimize costs
This code stops running instances at 5pm and starts them at 9am every weekday (Mon - Fri). Lambda runs the actual python functions that start and stop instances, while Eventbridge sets a schedule and triggers the Lambda functions at specified times. With an automation strategy such as this, you can effectively reduce AWS expenditure without compromise on performance or functionality.
## Prerequisites
- An AWS account
- Terraform installed on your local system
- One or more running AWS instances
## To run:
