Most developers would be more familiar with DevOps and less familiar with GitOps despite using Git, the source of truth of GitOps for managing repositories of the software development life cycle (SDLC). Hence, there is a need to study GitOps vs DevOps to ascertain which is suitable for your software development, delivery, and deployment. While both are designed to improve software processes, the two concepts; GitOps and DevOps are distinct in their approaches, guiding principles, and toolsets. Whether you are choosing GitOps or DevOps for your software processes, GitOps and DevOps are designed for various purposes and are best at their designated use cases.
This article will guide you beyond the fundamental differences and similarities between GitOps vs DevOps to providing a thorough understanding of how DevOps and GitOps methodology operate and what makes them uniquely valuable in modern software engineering. You would also learn how platform engineering portals like Atmosly make DevOps and GitOps better.
Understanding DevOps and GitOps
What is DevOps For Developers?
Imagine a software development process where development and operations teams work in isolation, following the traditional waterfall methodology. DevOps emerges as the bridge that brings these teams together. DevOps, short for Development and Operations, represents a cultural shift, a set of practices, and a toolkit that fosters collaboration and communication between development (Dev) and IT operations (Ops) teams. Its primary goal is to reduce the software development lifecycle, increase software release frequency, and elevate the quality of delivered software products.
What is GitOps For Developers
GitOps is a relatively new idea in DevOps, using Git, as the source of truth. It originates as a more developer-centric DevOps approach to automate tasks and improving communication between developers and operators on a version control system called Git. Instead of integrating another layer to manage changes, GitOps essentially allows organizations to operate software using the same version control techniques used for code changes, enabling teams to achieve continuous delivery capabilities, improved visibility, audibility, flexibility, and scalability in less time.
Key Differences Between GitOps vs DevOps
The two seem to have lots of similarities, however, there are differences between DevOps and GitOps. The points below allow you to choose whether you need DevOps or GitOps for your software processes.
| Aspect | GitOps | DevOps |
|---|---|---|
| Version Control vs. Scripting | Leverages Git for version control. Provides better visibility and traceability within Git. | Relies on scripts and automation tools for managing infrastructure and applications outside Git. |
| Procedural vs. Declarative | Takes a declarative approach. Defines the desired system and lets automation tools handle it. | Follows a procedural approach where developers specify a series of steps to achieve a goal. |
| Manual vs. Automated Synchronization | Integrates automated synchronization. Changes in Git repositories trigger automatic adjustments to the live environment. | Often involves manual interventions, even with automation. |
| Change Approval Process | Integrates change management into the Git repository workflow. Changes are reviewed, approved, and tracked within the system. | Relies on ticketing systems and human approvals for change management. |
| Ecosystem and Tooling | Maintains a focused toolkit with specialized tools for Git-centric workflows and declarative infrastructure. | Offers a wide array of practices and tools, including CI/CD pipelines and configuration management solutions. |
How GitOps Works: Simple and Streamlined
GitOps keeps it simple and efficient. Here's how it works:
- Version Control: Git is everything in GitOps. All configurations, from infrastructure settings to application code, reside in a Git repository. It's your one-stop master document.
- Declarative Configuration: No need for complex scripts as seen on DevOps. In GitOps, you declare what your system should look like, you tell it what you want, all on the Git
- Automation: CI/CD pipelines continuously monitor the Git repository for changes. When they spot something new, they automatically apply it to your live system, just like a robot following instructions.
- Self-Healing Systems: GitOps systems are intelligent. If they notice a discrepancy between reality and your "desired state" in Git, they automatically fix it. Your system stays on track.
- Immutable Infrastructure: GitOps encourages the use of "immutable infrastructure." When changes are needed, the entire infrastructure is replaced with a new, improved version. It's like upgrading your entire home instead of fixing a leaky faucet.
How DevOps Works: Collaborative and Agile
DevOps brings people together for a harmonious software development dance. Here's how it unfolds:
- Collaboration: Developers and operations teams work side by side. No more silos. It's like a well-coordinated dance routine where everyone knows their part.
- Automation: Automation is the superhero. DevOps tools automate tasks such as building, testing, and deploying code. It's like having a magical assistant that takes care of repetitive work.
- Continuous Integration (CI): Developers regularly merge their code changes into a shared repository. Automated tests run to catch any issues early, like having a diligent friend double-check your work.
- Continuous Delivery (CD): Code changes are automatically deployed. It ensures your code is always ready to go live. No more last-minute rushes!
- Monitoring and Feedback: DevOps teams use monitoring tools to keep an eye on applications and infrastructure. If something goes wrong, they quickly receive feedback, like having a guardian angel watching over your creations.

GitOps vs. DevOps: Which approach should you choose?
The decision between GitOps and DevOps hinges on your organization's goals, existing infrastructure, and tech stack. You can consider these factors:
- DevOps: If your organization has established processes and tools, DevOps offers flexibility and adaptability to various technologies and environments.
- GitOps: GitOps is ideal for cloud-native and containerized applications. when you have declarative infrastructure and automated synchronization, GitOps is your go-to method. It excels when version control and suitability are paramount.
In Conclusion
GitOps and DevOps are two distinct methodologies, each offering its unique approach and set of tools for software teams. While DevOps emphasizes collaboration, automation, and infrastructure adaptability, GitOps trusts version control, declarative infrastructure, and automation to simplify the process. Both sharing a common goal, share a common goal: streamlining software delivery, improving quality, and reducing manual effort.
The choice between these methodologies should largely depend on:
1. Your organization's needs
2. context
3. existing technology.
