How Enterprises Can Benefit from GitOps – The New Stack

As companies become more digital and software-driven, they turn to software delivery and digital transformation to drive growth. In this digital age, software is critical to every aspect of the business. Developers become the focal point while software drives the growth of the organization. As a result, organizations need to choose the right set of technologies, tools, and practices to help their developers do a better job.
Companies have embraced the idea of code revision and code optimization (which is code revision taken to the next level) to help developers write better code. Similarly, they have also adopted DevOps and other native cloud best practices to make the entire software deployment process very smooth. GitOps is a new entrant into the industry, facilitating software deployment. It is also a term that has become popular in recent years in the software development market. This article explores the concept of GitOps.
What is GitOps: A detailed introduction
The term “GitOps” was coined by Alexis Richardson of Weaveworks in 2017. GitOps is a native cloud-based approach that aims to speed up the software deployment process by using the power of the push / pull mechanism used by the control system. open source git versions as a single source of truth. It enhances the IC / CD of Kubernetes-related deployments and easily manages the infrastructure. A more holistic approach is needed to manage the code, making it easier to keep track of code changes.
It is an evolution of the traditional practice of CI / CD (Continuous Integration and Continuous Delivery) that aims to automate the entire deployment pipeline. Git is used as the sole source of truth for all infrastructure and application code changes. GitOps creates an automated deployment pipeline for your infrastructure. The goal is to make it possible for developers to collaborate on infrastructure changes without knowing the underlying systems. This way, developers can work on code in their own environment without worrying about affecting production systems.
In simpler terms, GitOps is a handy DevOps to provide visibility into the production environment. Provides an audit trail of changes made to production environments, which can be useful during troubleshooting. It also makes it easier to identify when the changes were made and who. GitOps also provides an easy way to reverse changes that may have caused production issues.
Many of you may be wondering, “How is GitOps different from DevOps?” Below is a self-explanatory comparison chart.
GitOps and CI / CD: hand in hand
Given the flexibility and agility of current software development, it makes sense for most software companies to adopt a continuous delivery (CD) model. Software development has become continuous, with the ability to launch software quickly, iterate products and services to find early errors, and increase services as needed. It is important to remember that any approach to software development is an ongoing process. Even when you adopt a more traditional software development model, you are still involved in continuous software development with each new release. To keep your software development process streamlined and consistent, you need to adopt an integrated software delivery model that seamlessly integrates the various stages of software development.
Continuous integration and continuous deployment are the key pillars of iterative software development. The approach involves automating the code testing process each time it is sent to a repository and automating the code merging process of different developers each time the new code is ready for release. The result is a faster iteration of the software code and a more streamlined development process that leads to fewer bugs and more frequent releases.
With the emergence and popularity of native cloud platforms like Kubernetes, GitOps is becoming a default approach to deploying applications. The developers find GitOps useful and easy to use because of its simplicity and minimal learning curve. An agent-like technology will track changes and, if there is a difference in the actual and desired state, make the changes meet the desired state, so the system always runs as it is. specifies.
GitOps makes it easy to manage pipelines with a simple approach. If you’ve been working in an environment around software revisions, you’ve probably heard the term “Pipeline Management” before. In short, a continuous delivery pipeline is a series of procedures designed to help developers publish code frequently and reliably, and this can be further simplified using GitOps.
Why is GitOps important?
The code / software deployment process was often thought to be manual, but no more! Iterating the code and deploying it are not things that developers like to do manually, which is boring, time consuming and tedious. Developers love the super-fast stuff, tools, and approaches that make their job easier. This whole process of deploying software, maintaining and tracking can be made easy with GitOps.
Not only that, GitOps doesn’t require developers to learn another brilliant new tool; uses git extensively and developers are already experts in using it. Git and its solid extension ecosystem give developers a more efficient way to manage their code. The changes made will be seen with a simple pull / sync. GitOps makes it easy to manage configuration and software deployments; this is what developers like to do instead of tedious configurations and coded scripts.
Getting Started with GitOps
For some, GitOps may be relatively new and may require some guidance. We are very optimistic about the GitOps approach here at Harness, and our engineers are working on a superior GitOps experience for you. Because Harness is already known for its modern continuous delivery platform, we know how to optimize your workflows and pipelines to streamline your software development activities.
For companies that have adopted microservices and DevOps practices, GitOps is an added benefit. Manual CI / CD and using scripts to automate piping requires a lot of time and effort from developers. So taking the GitOps approach will free your developers to work on important things that matter.
Suppose you use a source control management system such as GitHub, where your code repository resides, and practice containerization with Docker. The next step, obviously, would be to use an orchestration system like Kubernetes to manage and deploy your applications so that GitOps works well with Kubernetes. Kubernetes is usually represented as a declarative system where we specify things using YAML files.
GitOps looks at and scans our source control repository for our manifest files and compares it to what should be running in production. Then, if something changes in the manifest files or if you find any difference, pull and start synchronizing the changes to keep the actual and desired states identical. In this way, GitHub becomes a single source of truth. The ultimate goal of using GitOps is that the entire system and settings are managed declaratively, not just the applications.
GitOps continues to gain strength as more communities support this new approach, and the prediction is that it will be the standard deployment practice for companies working with Kubernetes. GitOps gives developers more control over their code and helps speed up deployment. With the adoption of fast-growing Kubernetes, GitOps is a blessing in disguise to help companies deploy their software in a much simpler way.
