About Terraform
- HashiCorp Terraform is an infrastructure as code tool that lets you define both cloud and on-prem resources in human-readable configuration files.
- You can version, reuse, and share these file.
Infrastructure as a code (IaC)
- IaC is the process of managing and provisioning computer resources through machine (and human) readable definition files
- The IT infrastructure managed by this process comprises both physical equipment, such as bare-metal servers, as well as virtual machines, and associated configuration resources.
- The definitions are generally kept in a version control system
- The code in the definition files may use either scripts or declarative definitions, but IaC more often employs declarative approaches.
- Other IaC Examples:
How does Terraform work
- Terraform uses plugins called providers that can access any platform or cloud provider.
- There are thousands of providers that are created both by the terraform community and Hashicorp.
- Terraform then creates
resources, for example:
- a compute instance
- a file storage
- a database instance
- a cloud network
- etc.
