GitOps
“DevOps is the union of people, process, and products to enable continuous delivery of value to our end users.” – Donovan Brown of Microsoft

TLDR: GitOps is a DevOps methodology that uses Git as a single source of truth for declarative infrastructure and application deployment. Introduced in 2017 by Weaveworks, it enables teams to manage and automate their infrastructure through Git repositories, ensuring consistent, reproducible, and auditable git workflows. By leveraging Git, GitOps integrates continuous delivery with version control, simplifying deployment processes and rollback procedures.

In a GitOps workflow, the desired state of a system is defined in configuration files stored in a Git repository. Tools like ArgoCD and Flux continuously monitor the repository and ensure the actual state of the infrastructure matches the desired state. When changes are committed to the repository, these tools apply the updates automatically, eliminating manual intervention and reducing the risk of errors. The use of declarative configurations ensures that every modification is traceable, enhancing security and compliance.
GitOps offers numerous benefits, including improved collaboration, faster deployment cycles, and easier rollback through Git’s version history. It is particularly well-suited for Kubernetes environments, where declarative configurations are standard practice. By combining infrastructure-as-code principles with Git-based workflows, GitOps enables teams to streamline operations, maintain consistency, and achieve greater reliability in modern cloud-native deployments.

- Snippet from Wikipedia: GitHub
GitHub () is a proprietary developer platform that allows developers to create, store, manage, and share their code. It uses Git to provide distributed version control and GitHub itself provides access control, bug tracking, software feature requests, task management, continuous integration, and wikis for every project. Headquartered in California, GitHub, Inc. has been a subsidiary of Microsoft since 2018.
It is commonly used to host open source software development projects. As of January 2023, GitHub reported having over 100 million developers and more than 420 million repositories, including at least 28 million public repositories. It is the world's largest source code host as of June 2023. Over five billion developer contributions were made to more than 500 million open source projects in 2024.
- Snippet from Wikipedia: DevOps
DevOps is the integration and automation of the software development and information technology operations. DevOps encompasses necessary tasks of software development and can lead to shortening development time and improving the development life cycle. According to Neal Ford, DevOps, particularly through continuous delivery, employs the "Bring the pain forward" principle, tackling tough tasks early, fostering automation and swift issue detection. Software programmers and architects should use fitness functions to keep their software in check.
Although debated, DevOps is characterized by key principles: shared ownership, workflow automation, and rapid feedback. From an academic perspective, Len Bass, Ingo Weber, and Liming Zhu—three computer science researchers from the CSIRO and the Software Engineering Institute—suggested defining DevOps as "a set of practices intended to reduce the time between committing a change to a system and the change being placed into normal production, while ensuring high quality". However, the term is used in multiple contexts. At its most successful, DevOps is a combination of specific practices, culture change, and tools.
