+**Q: Does Atlantis affect Terraform [remote state](https://developer.hashicorp.com/terraform/language/state/remote)?**
 
 A: No. Atlantis does not interfere with Terraform remote state in any way. Under the hood, Atlantis is simply executing `terraform plan` and `terraform apply`.

+**Q: How does Atlantis locking interact with Terraform [locking](https://developer.hashicorp.com/terraform/language/state/locking)?**
 
 A: Atlantis provides locking of pull requests that prevents concurrent modification of the same infrastructure (Terraform project) whereas Terraform locking only prevents two concurrent `terraform apply`'s from happening.

 Atlantis is doing is running `terraform plan` and `apply` and so all of the
 locking built in to those commands by Terraform isn't affected.
