	igw (associate with vpc)
------------------------------

Terraform part of it:
	s3 backend?

	system dir-->s3 bucket + dynamodb (provider block), two rsources s3 + dynadmodb

When you use s3 bucket (10 terraform)-->current state -->Terraform apply (locking will be enabled

	Lock-->key: value
	networking dir--> provider+backend (s3bukcet, and key (statefile)
	VPC-->subnet->igw-->routing-->routing table association
	sg (443,80,22) key-pair
	ssh-keygen
	keypair (public key)

	EC2 instance
	instance dir-->provider+backend ( only key will change)
	need data block(fetch datablock)
	aws_instance type resource (any Linux os)
