DevOps Tools – Terraform vs. Ansible

we compare two top-notch DevOps tools – Terraform vs. Ansible. This should be an interesting comparison, considering how immensely popular both these tools are in the market today. We will cover some key points about both the tools and try to understand which tool among the two works best in which situation.

HashiCorp Terraform is an open-source Infrastructure-as-Code management tool created chiefly for orchestration and provisioning in data center environments. By itself, Terraform does not directly configure or install applications or software. Terraform is mainly used for creating, changing, and destroying servers to reach a particular desired end state. As a tool, Terraform has a declarative approach to network management.

Red Hat Ansible is also an Infrastructure-as-Code management tool. However, compared to Terraform, Ansible uses a procedural approach. This is the main way Ansible is different from Terraform – their approaches. With Ansible, user-defined steps are used in a configuration for achieving a desired state or change. So, if intend to add installations or software over existing networks, Ansible would be your go-to tool. Besides, Ansible is agentless, uses SSH or other authentication methods for communication, and is lightweight & efficient.
