Development pipelines, applications, and configuration of all possible applications for GitOps.

Using Git as a single point of truth, GitOps is a method for deploying in software development and managing applications and infrastructure. The desired state of an application or infrastructure is stored and versioned using Git, and automation tools are used to ensure that the actual state matches the desired state. This makes it simple to collaborate, do rollbacks, audit, and manage changes by using standard Git workflows. GitOps is a cloud-native technologies tool. DevOps and GitOps are two well-known approaches to software development that aim to increase development efficiency.

Software development will be altered in three ways by GitOps.

1. The shift to immutability means that a commit or file in a Git repository cannot be changed after it is added. There are several advantages to this immutability, including:

• Audience: Because Git is immutable, it is simple to keep track of changes and comprehend who, when, and why they were made. This makes it easier for teams to audit their codebase, and find and fix problems.
• Continuity: Viewing a repository or file’s entire history is simple with Git. This makes it simple to comprehend the evolution of a particular application or file over time, which can be useful for debugging issues or determining the root cause of a problem.
• Repeatability: Git commits are immutable, so developers don’t have to worry about breaking the application or losing data when rolling back to an earlier version of the codebase. This ensures that the application is always in a known, working state and allows teams to quickly recover from issues.
• Working together: Because of its immutability, Git makes it simple for multiple developers to collaborate on the same codebase without worrying about data loss or conflicts. Teams can work together on changes and make sure that only changes that have been approved are put into production by using tools like branches, pull requests, and others that are built on Git.

2. When utilizing GitOps, developers can suggest modifications to the application or infrastructure in the following ways:

• Create a branch for features: In the Git repository, developers can make changes to a new branch, then submit a pull request to have them reviewed and merged. This lets teams work together on changes and makes sure that only changes that have been approved are put into production.
• Employ pull requests: A pull request, which developers can use to submit their changes, can be reviewed and approved by other team members before being merged into the main branch. Before the changes are put into production, this gives teams a chance to look over them and talk about any potential problems.
• Use the ‘issue following’ feature: In the Git repository, developers can report bugs or make changes by opening an issue. This makes it simple to see the status of a particular issue or pull request and allows teams to track and discuss changes in a single location.
• Use tools for code review: Code review tools let developers automatically look for errors and security holes in the code. This helps to ensure that the main branch only contains high-quality code.
• Keep an eye out for: The application’s and infrastructure’s status can be monitored by developers, who can be notified of any problems; this assists in quickly identifying and responding to any issues and ensuring that the application and infrastructure are operating as expected.

Developers can suggest changes and report problems using these techniques in a controlled and effective manner, assisting in the rapid and secure deployment of changes.

It is essential to keep in mind that the specific procedure for suggesting changes may differ based on the procedures and tools utilized by the organization. However, the above methods provide a general idea of how GitOps can be used to suggest changes.

3. GitOps uses Git as the single source of truth for both application and infrastructure code. Git captures all environment information. Teams can easily view the entire history of the codebase and comprehend how it has developed over time because Git tracks all changes. An audit trail can be used for the following:

• Enhance traceability: Teams can view a file or repository’s entire history with Git, making it simple to comprehend how a particular application or file has developed over time. Debugging issues or determining the root cause of a problem can be made easier with this.
• Guarantee compliance: The immutability of Git ensures that every change is recorded and tracked, which can be useful for complying with regulations. The Git history can be used by auditors to see precisely what changes were made and which can be used to show that the company complies with industry regulations.
