Mastering Loops and Conditionals in Terraform

Day 10 of my Terraform journey was all about writing less repetitive infrastructure code. Up to this point, most resources had been declared one by one. That works for small labs, but it becomes painful fast when you need multiple IAM users, repeated rules, or environment-specific behavior. Today I learned the four Terraform tools that make configurations dynamic: count for_each for expressions ternary conditionals This was one of the most practical Terraform topics so far. Why This Matters Terraform is declarative, but these features make it feel much closer to a programming language. They help you: reduce repetition create multiple resources safely transform data cleanly make infrastructure behavior change by environment They are also heavily tested in the Terraform Associate exam. 1. Loops with count count is the simplest loop in Terraform. Use it when you want Terraform to create a fixed number of similar resources. resource "aws_iam_user" "example" { count = 3 name = "user-${count
