GitOps: the best way to automate infrastructure management
DevOps has changed the game, transforming software development through automation and collaboration to speed things up, improve code quality, and make scaling simple. GitOps is the natural next step, applying DevOps best practices to infrastructure automation to increase speed and productivity, without compromising security or stability, and improve your developer experience.
What is GitOps?
GitOps is an operational framework applied to infrastructure and configuration automation. It incorporates familiar best practices, such as collaboration, version control, continuous delivery/deployment (CD), and compliance, and applies them to infrastructure automation.
In GitOps, everything from applications and networking to computing resources and storage is represented as code. But it's not version-control-system agnostic. It leverages Git, following a branch, code, check, merge (or pull request) workflow to develop the codebase, all of which can be controlled through automation.

In this eBook, we explain what GitOps is and get under the skin of this operational framework.
Benefits of GitOps
Power productivity and collaboration
GitOps simplifies processes, enables streamlined collaboration, and provides greater visibility for DevOps teams to maximise productivity.
Speed up development and deployment
GitOps eliminates configuration differences, leading to faster and more frequent deployments, optimising feedback and delivering more value to customers.
Make your developers happy
With predictable and repeatable application environment configurations, developers can focus on their work, enhancing employee satisfaction and retention.
Reduce costs
GitOps reduces downtime, thanks to built-in deployment and roll-back functionality, and facilitates easier cloud resource management, resulting in significant time and effort savings.
Be compliant, be stable
GitOps allows for faster iterations without compromising stability and reliability. Having a single source of truth makes recovery easier, and an audit trail for code reviews and compliance is provided.
Stay secure without compromise
With pull requests and the GitOps operator, anyone can propose changes while maintaining the integrity of the production branch and ensuring the security.

How to implement GitOps

GitOps challenges
GitOps faces challenges, including its focus on infrastructure and deployment rather than end-to-end software development. While it provides an audit trail, it only applies to infrastructure changes, which can be time-consuming to manage in complex applications. Familiarity with Git and pull requests is essential for GitOps adoption. Maintaining a clear record of pull requests and issues and avoiding direct edits in production requires commitment and governance. Achieving visibility and accountability may be easier in smaller organisations due to simpler structures. Despite these challenges, GitOps offers observability and visibility into the deployment process. Addressing these considerations and planning accordingly can ensure the successful implementation and management of GitOps in both small and large organisations.

Frequently asked questions
What’s the difference between GitOps and DevOps?
The main difference between GitOps and DevOps is the latter involves a cultural change, whereby development and operations come together to help organisations build and improve products quickly and efficiently, but the tools you might use as part of your DevOps approach can vary.
GitOps, on the other hand, is a specific operational process tied to Git. It is an advanced application of DevOps principles, optimising Git as the single source of truth. GitOps primarily focuses on managing infrastructure through Git, empowering developers to control and trigger deployments. By adopting GitOps, organisations leverage Git's capabilities to manage and automate their infrastructure, ensuring consistency and traceability.
What are the main principles of GitOps?
There are four key principles that apply when implementing your GitOps initiative:
1. A declarative system – GitOps focuses on specifying the desired end-state rather than the steps to achieve it. Users define the desired state, making it easy to store and manage in Git.
2. Versioned and immutable – with Git as your single source of truth, your desired state is stored in a way that enforces immutability and versioning. Complete version history allows for easy rollback, adherence to security measures through commit auditing, and analysis of changes over time.
3. Automatic pulling – with declared states held in Git, software agents automatically pull desired state declarations from the source. Once updated and approved, automation ensures that the desired state is consistently applied without human intervention.
4. Continuous reconciliation – software agents continuously observe and compare the actual system state to the desired state. If discrepancies or unexpected changes occur, immediate alerts are triggered, enabling proactive resolution.
What is a GitOps workflow?
Other than using Git, you don’t need a specific product or platform to do GitOps. But you will need to incorporate IaC, pull requests, and CD so your workflow looks something like this:
- The main branch can represent an environment (dev, test, production).
- You can implement changes in the feature branch.
- Then, you submit a petition to change the main branch (also referred to as a pull request or merge request).
- Infrastructure owners can then collaborate, review, and give feedback on the pull request to approve or reject the change.
- If the pull request/change is approved, the GitOps operator will notice the change in state. The GitOps operator then compares the desired state with the state of the existing infrastructure. Wherever there’s a mismatch, the system automatically reconciles the difference by overwriting the existing state with what is described in the Git repository.
How do I implement GitOps?
- Assess suitability: Determine if your organisation is ready to embrace the software delivery culture and evaluate your application delivery pipeline to determine if GitOps would be beneficial.
- Design and Implement best practices: Develop and implement best practices for your infrastructure team to follow and adopt new solutions. Utilise external experts, leverage existing internal knowledge, and provide training to upskill your team.
- Choose deployment pipeline approach: Decide whether to have a dedicated pipeline for infrastructure changes, integrate them into existing pipelines, or adopt a hybrid approach based on your organisation's specific needs and requirements.
