Terraform, by HashiCorp is an open-source infrastructure as code tool. Terraform is used by DevOps to automate infrastructure tasks. With infrastructure being codified, modifications of infrastructure are automated. Terraform is used to establish infrastructure across multi-cloud and on-prem data. It is also known for its use of a simple syntax, qualifying it as a prominent automation tool.
Terraform uses Infrastructure as code(IaC) as an instrument to automate the management and provision of infrastructure through code, as opposed to manually. With thanks to automation, it is significantly faster to deploy or connect resources. Infrastructure as Code allows you to manage and provision infrastructure through readable declarative configuration files.
