Quick Answer
DevOps is a broad set of cultural practices and tools that improve collaboration between development and operations teams. GitOps is an operational framework within DevOps that uses Git as the single source of truth for managing infrastructure and deployments.
In Simple Terms
DevOps is the overall approach to faster and reliable software delivery.
GitOps is a method of managing infrastructure and deployments using Git repositories.
Why This Comparison Matters
As DevOps matured, teams needed a more structured way to manage infrastructure and deployments. GitOps emerged to bring consistency, traceability, and automation using version control.
What DevOps Focuses On
DevOps includes:
-
CI/CD pipelines
-
Automation of testing and deployments
-
Collaboration between teams
-
Monitoring and feedback loops
DevOps covers the full software lifecycle.
What GitOps Focuses On
GitOps uses Git repositories to define the desired state of infrastructure and applications.
Key principles include:
-
Git as the single source of truth
-
Declarative infrastructure definitions
-
Automated synchronization between Git and production
-
Pull requests for changes
GitOps improves control and traceability.
Key Differences Explained
| Aspect | DevOps | GitOps |
|---|---|---|
| Scope | Broad methodology | Specific operational model |
| Focus | Collaboration + automation | Infrastructure & deployment via Git |
| Change Process | Multiple tools and processes | Git pull requests |
| State Management | Often manual or tool-driven | Git defines desired state |
How GitOps Works
-
Infrastructure and application configurations are stored in Git.
-
Changes are made through pull requests.
-
Automated systems detect changes in Git.
-
Systems update environments to match the desired state.
Benefits of GitOps
Improved Consistency
All environments are defined in version-controlled code.
Better Auditability
Every change is tracked through Git history.
Faster Recovery
Systems can be restored by reverting Git changes.
Enhanced Security
Access is controlled through Git permissions and reviews.
Real-World Example
A cloud-native company uses Git repositories to manage Kubernetes configurations. When a change is merged, automation tools update the production cluster automatically.
Who Should Understand GitOps
-
DevOps engineers
-
Cloud engineers
-
Kubernetes administrators
-
SRE teams
-
Students learning modern infrastructure practices
Summary
DevOps provides the overall framework for software delivery, while GitOps offers a Git-driven model for managing infrastructure and deployments reliably.
