Modern infrastructure teams need reliable ways to provision resources, manage configurations and deploy changes consistently. Infrastructure as Code (IaC) and GitOps both help reduce manual work, but they solve different problems. Understanding GitOps vs. Infrastructure as Code helps technology teams choose the right approach for cloud infrastructure, Kubernetes environments and application delivery.
Although the two practices often work together, they are not interchangeable. IaC defines infrastructure through code, while GitOps uses Git as a central source of truth for managing and reconciling system state.
What is Infrastructure as Code?
Infrastructure as Code is an approach to provisioning and managing infrastructure through machine-readable configuration files instead of relying entirely on manual setup.
Teams use IaC tools to define resources such as virtual machines, networks, storage, databases and cloud services. These definitions can be version-controlled, reviewed, tested and reused across environments.
For example, an organization can define its cloud network and compute resources in configuration files, then use an IaC tool to create or update those resources.
Key benefits of IaC include:
- Consistent infrastructure configurations across environments.
- Faster provisioning and easier resource replication.
- Version history and reviewable infrastructure changes.
- Reduced manual configuration errors.
- Better integration with automated deployment pipelines.
IaC can be used through command-driven workflows, automated pipelines or other deployment processes. It does not inherently require GitOps.
What is GitOps?
GitOps is an operational approach in which Git repositories store the desired state of systems and automated processes help keep the actual environment aligned with that state.
A typical GitOps workflow involves engineers committing configuration changes to a repository. After review and approval, an automated controller detects the desired state and applies or reconciles changes in the target environment.
GitOps is commonly used for Kubernetes application deployments and cluster configuration management. It can also support broader infrastructure workflows when the relevant tools and architecture are designed for that purpose.
Key benefits of GitOps include:
- A central, version-controlled record of desired configuration.
- Auditable changes through commits and pull requests.
- Continuous reconciliation between desired and actual states.
- Easier identification of configuration drift.
- More consistent deployment and rollback workflows.
GitOps does not eliminate the need for access controls, testing or monitoring. Poorly reviewed changes can still introduce errors, even when the deployment process is automated.
GitOps vs. Infrastructure as Code: 5 Key differences
1. Primary Purpose
IaC focuses on defining and managing infrastructure resources through code. GitOps focuses on operating systems by using a version-controlled desired state and automated reconciliation.
For example, IaC can define a Kubernetes cluster, while GitOps can manage the applications and configurations deployed to that cluster.
2. Source of Truth
IaC configuration is often stored in Git, but the workflow may involve an engineer or pipeline manually initiating changes.
In a GitOps workflow, the Git repository serves as the declared source of truth for the resources managed by that workflow. Controllers continuously or periodically compare the desired state with the running environment.
3. Deployment and Reconciliation
IaC tools commonly create, update or remove resources when an operator or pipeline runs a deployment operation.
GitOps controllers can repeatedly reconcile the environment with the approved configuration. This helps detect and correct certain forms of configuration drift, depending on the controller and its settings.
4. Common Use Cases
IaC is widely used to provision cloud infrastructure, configure networks, create databases and manage resource lifecycles.
GitOps is frequently used for Kubernetes deployments, application configuration, cluster add-ons and declarative operational workflows.
There is substantial overlap: infrastructure provisioning can also be managed through GitOps when suitable controllers and processes are available.
5. Operational Controls
IaC workflows often rely on plans, code reviews, deployment approvals and policy checks. GitOps workflows add reconciliation mechanisms and commonly use repository-based approvals to control changes.
Both approaches need testing, least-privilege access, secrets management and monitoring.
Can organisations use GitOps and IaC Together?
Yes. They are often complementary rather than competing approaches.
An organization might use IaC to provision cloud networks, databases and Kubernetes clusters. It can then use GitOps to deploy applications and manage cluster configurations. Some platforms also support GitOps-driven infrastructure provisioning.
The most suitable design depends on team skills, platform requirements, change frequency and operational risk. Organisations should clearly define which tool owns each resource to prevent multiple systems from making conflicting changes.
Final Thought
The difference between GitOps and Infrastructure as Code comes down to their primary roles. IaC defines infrastructure through code, while GitOps uses version-controlled desired state and automated reconciliation to manage systems.
For The Mainstream readers, combining the two can improve consistency, traceability and operational control. The best results come from clear ownership, reliable testing and a workflow that fits the organization’s infrastructure and delivery needs.
