With Backends and Remote State all state is stored remotely instead of locally which is the default. This allows terraform to be ran from any machine which could be a CI/CD setup and multiple developers can work on the same infrastructure without overriding any configuration. Some common backends to store state are AWS S3 buckets or Azure storage blobs.

In this video tutorial I'll go over setting up a remote backend in AWS S3 to store all of our state.

Running terraform init to initialization our backend
