On day 4 of my learning journey I learnt how Terraform remembers what it creates, and how to manage that memory safely using a remote backend. When running terraform apply , a file named terraform.tfstate is generated in the working directory. This file is critical because it stores metadata that Terraform uses to track infrastructure resources. Why Remote State Matters When Terraform runs, it keeps track of infrastructure in a state file. If that file stays on a local machine: It’s not shareable It’s not safe It can easily get corrupted or lost StateFile Best Practices Store StateFile to a Remote Backend: The problem with Statefile is it also contains all the important information like configuration, access keys and other sensitive information. So we shouldn't log that to a github or any other personal folders. It is better to keep that in a Remote Backend like S3 in AWS, Blob in Azure and GCP Cloud Staorage. Do Not Update/Delete StateFile: StateFile will always be generated by Terraform.…
