AWS

To build own AWS infrastructure you need:

• terraform,
• AWS account (free tier is good enough)
• AWS CLI

First prepare configuration for aws-cli -> LINK When it is ready let's create some infrastructure in Cloud

cd iac
terraform init
terraform plan

In terminal will be printed a lot of new resources (33). Next let's apply it to AWS:

terraform apply
