Partner modules
Partner modules are reviewed by HashiCorp and actively maintained by contributors to stay up-to-date and compatible with both Terraform and their respective providers.
The partner badge appears next to modules that are published by a partner source.
Partner modules are expected to be actively maintained by HashiCorp partners. The partner badge isn’t indicative of a module's flexibility or feature support. We can mark simple modules as partner modules because they are great module examples. Likewise, an non-partner module could be extremely high quality and actively maintained. An non-partner module shouldn't be assumed to be poor quality, it only means it hasn't been created by a HashiCorp partner.
When using registry modules, there is no difference between a partner and non-partner module, you can use them the same way.
