Terraform Count vs. For Each Meta-Argument – When to Use It

In this article, the author explains the use of count and for_each meta-arguments in Terraform. These arguments help manage multiple resources without writing separate blocks of code for each one. The count argument accepts a whole number and creates the specified number of instances of the resource. Each instance has its own infrastructure object associated with it, allowing for individual management. The for_each argument, on the other hand, creates multiple instances of a module or resource block using a map or set of strings. It is useful when resources require different values.
