Terraform is an infrastructure as a code platform developed by HashiCorp. You can simply write code in the human-readable format following HashiCorp Configuration Language (HCL) and deploy it to get the infrastructure in the cloud.
With a combination of at least 2 tools, you can perform devOps role.  However, Kubernetes alone can take the place of these multiple tools in both setting up infrastructure and deploying applications in pods.
Terraform is mainly infrastructure provisioning tool that allows
·       Initial Infrastructure setup
·       Configure and Manage Infrastructure
