## Best Practices
An environment alone **should not** be used to manage the difference between
development, staging, and production. While it is technically possible, it is
much more manageable and safe to use multiple independently managed Terraform
configurations linked together with
[terraform_remote_state](/docs/providers/terraform/d/remote_state.html)
data sources.
development, staging, and production. As Terraform configurations get larger,
it's much more manageable and safer to split one large configuration into many
smaller ones linked together with terraform_remote_state data sources. This
allows teams to delegate ownership and reduce the blast radius of changes.
For each smaller configuration, you can use environments to model the
differences between development, staging, and production. However, if you have
one large Terraform configuration, it is riskier and not recommended to use
environments to model those differences.
The [terraform_remote_state](/docs/providers/terraform/d/remote_state.html)
resource accepts an `environment` name to target. Therefore, you can link
