If you're working on a Terraform project with a group and there's no remote backend to save a state file, the file will be saved locally. The use of a local file complicates the use of Terraform seeing as each user must ensure that they have the most recent state data before running Terraform and that no one else is running Terraform at the same time. To overcome this, you can store your State File on a remote backend storage like AWS S3 Bucket. This is one of our Terraform best practices.
