Terraform is server provisioning tool which is used for developing, changing and versioning infrastructure safely and precisely. Terraform has become favoured because it uses simple syntax which allows easy customization and works against multi-cloud. Terraform is written in Go language and it is an open source tool.

Terraform is an apparatus for building, changing, and versioning infrastructure securely and speedily. Terraform facilitate to use Infrastructure as Code to provision and manage any cloud, service or infrastructure. Terraform can manage existing and popular service providers as well as custom in-house solutions. Terraform connects to various service and helps create, configure and manage those services. The infrastructure Terraform manages can be hosted on public clouds like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), or on-prem in private clouds such as VMWare vSphere, OpenStack, or CloudStack.
