Terraform conditionals are expressions that allow you to dynamically set values based on the evaluation of specified conditions, enabling greater flexibility and adaptability in your infrastructure configuration.
Terraform loops, implemented using count or for_each meta-arguments, allow the creation of multiple instances of a resource or module based on an integer count or items in a map or set, simplifying repetitive resource configurations.
Terraform’s “create_before_destroy” approach ensures that when updating an existing resource, a new version is first created before the old one is destroyed to minimize downtime and data loss.
