  • More flexible than count
  • Works with maps and sets
  • Better for resources with unique configurations

count: Create multiple identical resources efficiently.
for_each: Iterate over sets or maps to create resources with unique properties.

  • Reduce code duplication.
  • Scale resources dynamically.
  • Customize resource configurations effortlessly.
