Can Terraform and Ansible be used together?

Yes, and it is a common pattern — Terraform provisions the infrastructure (servers, networks, databases), then Ansible configures what runs on it (software, settings, deployments). Each tool covers the part of the lifecycle it is built for.

Is Ansible agentless like Terraform?

Both are largely agentless in that neither requires permanent software installed on the resources it manages, but they connect differently — Terraform talks to cloud provider APIs to manage infrastructure, while Ansible connects directly to target machines over SSH to run configuration tasks.

Should I learn Terraform or Ansible first?

It depends on the problem in front of you — if you need to create cloud infrastructure from scratch, start with Terraform; if you already have servers and need to configure and deploy to them consistently, start with Ansible. Many engineers end up learning both, since real pipelines typically need both jobs done.

Is there a certification for Ansible like the Terraform Associate exam?

HashiCorp’s Terraform Associate certification validates Terraform specifically. Red Hat, which maintains Ansible, offers its own certification path covering Ansible automation — a separate credential for the configuration-management side of infrastructure automation.

Terraform vs Ansible: what is the difference?

By the SaveMyCert Editorial TeamPublished 14 Aug 2026Updated 14 Aug 2026

Terraform and Ansible are both infrastructure-automation tools, but they solve different problems — Terraform provisions and manages cloud infrastructure declaratively, while Ansible focuses on configuration management and application deployment, and many teams use them together rather than choosing one over the other. Both replace manual, click-through work with code, and both fall under the broader banner of infrastructure as code, but they operate at different points in the lifecycle of a system: one brings servers, networks and databases into existence, the other sets up what runs on them once they exist. Confusing the two — or assuming one makes the other redundant — is a common source of muddled architecture. This guide defines each tool plainly, compares them directly, and explains the honest answer of when and why you would use both.

What Terraform is

Terraform is a declarative infrastructure-as-code tool from HashiCorp. You describe the infrastructure you want — a virtual network, a set of servers, a managed database — in its configuration language, HCL, and Terraform works out the steps needed to create, update or remove real cloud resources to match that description. It tracks a state file recording what it has already created, which is how it knows the difference between infrastructure that needs to change and infrastructure that is already correct. Terraform is multi-cloud by design, using the same workflow and language whether the resources sit on AWS, Azure, Google Cloud or elsewhere. Our explainer on what Terraform is covers the tool itself in more depth.

What Ansible is

Ansible is an open-source automation tool from Red Hat, and it sits a step later in the process. Rather than provisioning cloud resources from scratch, Ansible focuses on configuration management and application deployment — installing software, applying settings, managing files and starting services on machines that already exist. It is agentless: it connects to target machines over standard SSH rather than requiring software to be pre-installed on them. Playbooks are written in YAML and describe a sequence of tasks to carry out, giving Ansible a more procedural, step-by-step feel than Terraform’s declarative model, even though it can also express desired end states for individual tasks.

The key differences

Set side by side, the two tools diverge on several dimensions:

Primary purpose — Terraform provisions infrastructure (create the servers, networks and databases); Ansible configures it (install and set up what runs on those resources).
Approach — Terraform is declarative and state-based, comparing a state file against reality and reconciling the difference; Ansible is closer to task- and playbook-based, running a defined sequence of steps.
Connection model — both are largely agentless, but Terraform talks to cloud provider APIs to manage resources, while Ansible connects to the machines themselves over SSH.
Language — Terraform uses HCL, its own declarative configuration language; Ansible uses YAML, structured as playbooks of tasks.
Change tracking — Terraform maintains a state file as the source of truth for what it manages; Ansible does not track state in the same way, and typically re-runs tasks idempotently instead.

It is not either/or

The most honest way to frame the comparison is that Terraform and Ansible complement each other rather than compete. A very common pattern in real infrastructure pipelines is Terraform provisioning the servers, networks and other cloud resources first, then Ansible taking over to configure the software and settings on those newly created machines. Used this way, each tool does the part of the job it is actually built for, and neither is stretched to cover the other’s territory — Terraform generally can install some software through provisioners, and Ansible can provision some cloud resources through modules, but both are working against their natural strengths when pushed that far.

When you would lean to each

Reach for Terraform when the task is bringing infrastructure into existence or changing its shape: standing up a new environment, adding a database, restructuring a network. Reach for Ansible when the task is about what happens on infrastructure that already exists: rolling out an application update, changing a configuration file across a fleet of servers, or applying a security patch consistently. In practice, most non-trivial cloud environments end up needing both categories of work at different points, which is exactly why the two tools are so often paired rather than treated as alternatives.

The certification angle

HashiCorp’s Terraform Associate certification validates Terraform specifically — its workflow, state management, and core language concepts — and is the natural next step for anyone who has started using it for provisioning. Red Hat also offers its own certification path covering Ansible automation, aimed at the configuration-management side of the picture. The two credentials are not competing for the same territory any more than the tools are; they simply validate different halves of an infrastructure-automation skill set. Our explainer on infrastructure as code covers the broader discipline both tools belong to.

Terraform provisions and manages cloud infrastructure declaratively, tracking a state file to reconcile what exists with what is desired; Ansible focuses on configuration management and application deployment on machines that already exist, running task-based playbooks over SSH.
