GitOps is a software development and operations methodology that uses Git as a single source of truth for the desired state of an application and its infrastructure. In GitOps, changes to the desired state are made by committing changes to a Git repository, and then automatically applying those changes to the live environment.
GitOps enables teams to collaborate on infrastructure and application changes, track changes, and roll back to previous states if necessary. It also provides an audit trail of changes and makes it easier to enforce infrastructure as code (IAC) practices, where the entire infrastructure is defined in code and version-controlled.
There are two main components of GitOps:
- Git repository: A Git repository is used to store the desired state of the infrastructure and applications. This repository can be a public or private repository hosted on GitHub, GitLab, Bitbucket, or any other Git-based platform.
- Continuous Deployment (CD) pipeline: A CD pipeline is used to automatically apply changes to the live environment. The pipeline is triggered by changes to the Git repository, and it verifies and deploys the desired state to the live environment.
GitOps is often used in combination with tools such as Terraform, Kubernetes, and Helm to manage infrastructure and applications. It is especially useful for organizations that are looking to automate and simplify their infrastructure and application delivery processes.
Advantages of GitOps:
-
Increased collaboration: GitOps enables teams to collaborate on
infrastructure and application changes by using a shared Git repository.
This makes it easier for teams to communicate changes and ensure that
everyone is working towards the same desired state.
-
Improved visibility: With GitOps, changes to the infrastructure and
application are version-controlled and easily auditable. This makes it
easier to track changes and troubleshoot issues when they arise.
-
Faster and more reliable deployments: With GitOps, changes are
automatically applied to the live environment as soon as they are
committed to the Git repository. This makes deployments faster and more
reliable, as the pipeline ensures that the desired state is always in sync
with the live environment.
-
Infrastructure as code (IAC): GitOps encourages the use of IAC practices,
where the entire infrastructure is defined in code and version-controlled.
This makes it easier to automate and manage infrastructure, and to revert
to previous states if necessary.
-
Improved security: GitOps enables organizations to enforce security
policies and standards by using automated pipelines to manage changes.
This reduces the risk of manual errors and helps to ensure that changes
are secure and compliant.
Disadvantages of GitOps:
-
Learning curve: GitOps requires a certain level of expertise in Git, as
well as a deep understanding of the underlying infrastructure and
applications. This can make it challenging for organizations to adopt
GitOps, especially if they have limited technical resources.
-
Complexity: GitOps can be complex to set up, especially for organizations
with complex infrastructure and applications. This requires a significant
investment in time and resources, and can be a barrier for some
organizations.
-
Dependency on Git: GitOps depends on Git, so organizations need to have a
reliable and secure Git infrastructure in place. This can be a challenge
for organizations that are not familiar with Git or that have limited
technical resources.
-
Integration with other tools: GitOps requires integration with other tools
such as Terraform, Kubernetes, and Helm. This can be challenging for
organizations that are not familiar with these tools, or that have limited
technical resources.
- Increased collaboration: GitOps enables teams to collaborate on infrastructure and application changes by using a shared Git repository. This makes it easier for teams to communicate changes and ensure that everyone is working towards the same desired state.

In conclusion, GitOps is a powerful methodology that can improve collaboration, increase visibility, and simplify infrastructure and application delivery processes. However, it also has some limitations, and organizations need to carefully consider whether it is the right approach for their needs.
