Hello, instructor. I am currently a student working on a project to build an infrastructure using Terraform in an AWS environment. I feel like my knowledge and learning are definitely accelerating because you kindly explain each step, so I don't regret the money. However, if there is something I regret, it would be great if you could add creating instances such as ec2, elb, and autoscaling with Terraform rather than s3 and iam. I am currently creating an ec2 instance using Terraform. If you have time, please tell me how to apply the secret key.pem key value that I have to the ec2 instance, and how to access it with ssh. ㅠㅠ Also, if there are cases where this is actually applied in practice, or things like that. ㅠ If there is an intermediate or slightly more advanced class, I will definitely buy it and listen to it!
