AWS already have ElasticBeanstalk which is a Heroku alternative. However, if you decide to build your infrastructure manually, use Terraform.

Or use CloudFormation that is supported by AWS and the technology behind Elastic Beanstalk, CodeStar, SAM, etc....

Agreed. Try to setup a template.yaml for CloudFormation, read the docs, try, get an error, retry... Until you have your perfect setup.

And then only make changes to the template, then package, then deploy.
