Although both Terraform and Ansible are DevOps technologies, how do they differ? In a nutshell, Terraform is an open-source Infrastructure as Code platform, whereas Ansible is an open-source configuration management tool that focuses on infrastructure configuration.

The question of whether to use Terraform or Ansible for infrastructure management is frequently debated. Fortunately, an answer can be found in the grey area. When persons with working experience on both tools are asked the identical question, the answer appears to be the same.

This article discusses the similarities and differences between Terraform and Ansible, as well as the best strategy to manage infrastructure.

Similarities

Given the capabilities of both technologies, Terraform and Ansible appear to be similar tools at a high level. They’re both capable of setting up the new cloud infrastructure and configuring it with the necessary application components.

Terraform and Ansible are both capable of running remote instructions on the freshly generated virtual machine. This signifies that neither tool has an agent. For operational purposes, there is no need to install agents on the machines.

Terraform creates infrastructure utilizing cloud provider APIs, and basic setup chores are completed via SSH. Ansible is the same way; it uses SSH to conduct all of the necessary configuration chores. Both tools are masterless since the “state” information does not require a separate piece of infrastructure to manage.

Differences

The preceding section provides an overview of the two tools in terms of their most fundamental commonalities. Both Terraform and Ansible appear to be capable of provisioning and configuration management at a high level. However, a closer examination reveals that one has advantages over the other in specific areas.

Overall, both tools are excellent in their own right. When it comes to infrastructure management, their functions overlap. Orchestration and configuration management are two components of infrastructure management.

When it comes to overlaps, Terraform and Ansible each have their own approaches, with strengths and weaknesses. To make a “perfect” pick or a combination with boundaries, it is necessary to delve into the aspects of both tools.
