GitOps vs. DevOps - What They Are And Why They Are Better Together

GitOps vs. DevOps - Introduction

In modern software development, two terms often pop up: GitOps vs. DevOps. While they share similarities, they are different concepts. In this blog post, we will define both concepts, explore their differences, highlight their similarities, and discuss how they complement each other. Additionally, we will touch on how open source tools like Lagoon leverage GitOps practices.

Defining GitOps vs. DevOps

GitOps Definition

GitOps is a methodology that emphasizes managing infrastructure and applications declaratively as code, using a Git repository as the source of truth for application code, deployments, and infrastructure operations. It extends the principles of Infrastructure as Code (IaC) to application deployments, making it possible to manage your entire tech stack through version-controlled code repositories.

Critical characteristics of GitOps include:

Declarative Configuration as code: All configurations for infrastructure and applications are stored in Git repositories as code. This approach promotes versioning, traceability, and collaboration.
Automation: GitOps relies on automation to continuously synchronize the system's desired state with the actual state, reducing manual interventions.
Reconciliation: A continuous reconciliation loop compares the desired state in Git with the actual state in the infrastructure and automatically makes the necessary adjustments.

DevOps Definition

DevOps is a team cultural and operational practice whose adoption is aimed at breaking down the traditional silos that have existed between development and operations (including deployment, infrastructure, security, etc) teams. DevOps encourages collaboration, communication, and automation throughout the software development lifecycle. DevOps principles include:

Continuous Integration (CI): Developers regularly integrate code changes into a shared repository, which is then built and tested automatically.
Continuous Delivery (CD): Once integrated, code can be continuously delivered to production or other environments with minimal manual intervention.
Automation: Automation is a central theme in DevOps, enabling consistent and repeatable processes.

Differences Between GitOps vs. DevOps

Here are the main top-level differences between GitOps and DevOps:

Feature	GitOps	DevOps
Concept	A practical methodology and software development approach that uses Git as the single source of truth for application code, infrastructure, and application deployment.	A software development methodology and team approach that emphasizes the breaking down of silos through collaboration and communication between development and operations teams.
Workflow	Automates the workflow from code to production using Git as the central hub for all changes.	Involves team culture, practical processes, and automation tools for code integration, testing, and deployment.
Deployment	Deployments are fully automated and triggered by changes in the Git repository.	Deployments are done either manually or by leveraging various degrees of automation.
Rollback	Rollbacks are fully automated and can be easily done by reverting to a previous Git commit. Developers AND operators get more time back.	Rollbacks are typically done manually and may require additional testing.
Auditing and Tracking	Git's built-in tracking and auditing capabilities make it easy to track and revert changes.	Auditing and tracking of changes relies on the team dynamic and the practices. DevOps teams can embrace GitOps to accomplish this.
Collaboration	GitOps' use of Git as the single source of truth facilitates collaboration and communication. This makes life easier for developers and operators since everything is centered around a single source of truth.	DevOps is all about breaking down silos. Thus, DevOps teams are, by nature, highly dependent on collaboration. Embracing approaches like GitOps increases this collaboration and smooths engagement.
Business Benefits	Provides consistency, reliability, and scalability while enabling faster time-to-market and easier rollbacks.	Is known to lead to faster time-to-market, but without transparent systems and processes, it can start to lack consistency and reliability over time.

However, GitOps vs. DevOps also differ in their approaches and focus areas:

Scope of Management

GitOps focuses primarily on managing infrastructure and applications through Git repositories.
DevOps covers a broader spectrum, including culture, processes, and tooling to enhance the entire software development and delivery pipeline.

Source of Truth

In GitOps, Git repositories serve as the single source of truth, ensuring all changes are version-controlled.
DevOps may rely on various tools and artifacts at different stages of the development pipeline.

Streamlined Development Processes

Since Git is the central repository of truth, developers can efficiently work together on code, track changes, and manage versions. This means they won’t need multiple tools and processes to manage all the code. Thus, the development process is much quicker and more efficient.
DevOps practices often come with manual processes and multiple tools required to manage and deploy code. This can get out of hand without clear decisions around single-source-of-truth repositories.

Deployment Process

GitOps uses declarative configurations to define the desired state, making it easier to achieve reproducibility and consistency.
DevOps can involve imperative scripting for deployment and orchestration, which can be more error-prone. This is why DevOps teams often embrace GitOps.

By showcasing the differences between the two concepts of GitOps and DevOps, we aim to show not only where they differ but also where, when the two concepts are used jointly, they can complement and support each other and make life as a dev so much smoother and more worry-free. In our opinion, with GitOps vs. DevOps, it’s never an either-or but a both-and!

Similarities Between GitOps vs. DevOps

Despite their differences, GitOps and DevOps share several common elements:

Automation: Both GitOps and DevOps emphasize automating processes to reduce manual intervention, improve efficiency, and ensure consistency.
Continuous Integration and Delivery: Both practices promote CI/CD, which helps streamline development, testing, and deployment.
Version Control: Git repositories are a fundamental component of both GitOps and DevOps, allowing for version-controlled code and configuration management.

GitOps vs. DevOps - A Complementary Relationship

GitOps vs. DevOps are not mutually exclusive; they can be highly complementary. Here's how they can work together:

Infrastructure Management: GitOps can manage infrastructure as code, while DevOps can focus on application development and delivery. Together, they ensure that the infrastructure and applications are consistently and automatically managed.
Visibility and Traceability: GitOps provides a clear audit trail and version history for all changes, enhancing transparency. DevOps teams can leverage this information for improved collaboration between development and operations teams.
Continuous Improvement: DevOps can continually optimize the development and deployment pipeline, while GitOps ensures that the infrastructure and application configurations are always in sync with the latest code changes.

What does GitOps help Developers do?

GitOps helps you maintain visibility and historical traceability, from beginning to end, with every aspect of development, Including from writing code to building, testing, and deployment. This means that developers have visibility into the DevOps activities.

GitOps embodies the spirit of DevOps in a developer-focused way, with a strong emphasis on code (literally everything is code.) GitOps helps unify all DevOps elements around a single source of truth, or a single Git repository, for anyone involved.

The most crucial benefit of adopting GitOps is that it can help developers do everything at their own pace without being bottlenecked by other teams or operations. Making changes through Git and having automation make the deployments means developers can do what they need to: Code without waiting for resources to be assigned or approved by other teams.

For operations teams, complete visibility means they can improve security because there’s a trackable record of everything they can follow. Overall, the benefits of your DevOps team using GitOPs are making your organization move faster, making the right changes, and speeding up timelines in an increasingly competitive business landscape.
