Terraform

Terraform is an infra management tool made by Hashicorp. It helps in provision, manage and maintain cloud resources. Terraform is not a config management tool.

Features

• Terraform deploys pre-made server images
• Base server images can be created with Packer, another open source tool by Hashicorp.
• Immutable infrastructure
• Disposable infrastructure - freely delete and replace any instance
• It can work with Docker and Kubernetes. It can also interact with AWS EKS.
• Terraform figures out the hard part of resource ordering and lets you just treat the infrastructure as static code.
