Resource types in the name is a pet peeve of mine. They should not be part of the name. An RDS instance can never be anything other than a database, no need for 'database' or 'db' or 'rds' in the name. Likewise a Kubernetes cluster can never be anything other than a k8s cluster. It doesn't need 'cluster' suffix. Terraform makes this redundancy especially obvious because you already include the type in any references…
How do you feel about Hungarian notation?
Possibly useful in dynamically typed languages. Definitely not useful at all in statically typed languages. And cloud resources are equivalent to statically typed - you cant turn an EC2 instance into an Elastic Load Balancer, for instance -- it's only ever one or the other.
