I'm using ec2 for development, and it's a waste of money after work. How much time does it take to create a scheduler that automatically starts every morning at 8 am and ends at 7 pm? I've read the guide provided by AWS, but it's a little difficult. https://aws.amazon.com/ko/answers/infrastructure-management/ec2-scheduler/

You can easily make your own scheduler using Amazon CloudWatch Events to trigger an AWS Lambda function on a regular schedule.
- Amazon CloudWatch Events has the ability to schedule events, such as triggering a Lambda function
- A Lambda function can do whatever you wish, such as starting/stopping instances based on a tag
See: Creating an Enterprise Scheduler Using AWS Lambda and Tagging
Though its difficult to implement to scratch, you can use ec2-scheduler.template to deploy the CloudFormation stack to provision the required platform to schedule.
This approach is more convenient than implementing it from scratch using a scheduled Lambda function and EC2 SDK.
It is also good to make your own guide based, it takes about a week.
Assuming a developer costs around $ 200 per day for a developer, it will take at least $ 1000 for five days of development. The CloudScheduler service is $ 10 per month, and if you have $ 1000, you can use the service for 100 months, about 4 years.
Service is cheaper than development. Just use the service.
