What Is GitOps and Will It Eliminate Incident Management?
What Is Incident Management?
Incident management is a critical aspect of IT service management (ITSM) that revolves around restoring normal service operations as swiftly as possible after an unplanned interruption or reduction in quality. Also referred to as “incidents,” these interruptions could range from a minor issue like a single user being unable to access a service to a significant problem such as a server crash or network outage affecting many users. Many organizations use alerting systems to escalate important incidents to relevant staff members.
Incident management is not just about resolving issues when they arise; it also includes the continuous monitoring of systems and networks to proactively detect and prevent potential incidents. The primary goal of incident management is to minimize the negative impact of incidents on business operations, ensuring that services are delivered at the highest quality at all times.
To achieve this, organizations typically have a structured incident management process in place, complete with a dedicated team, set procedures, and tools. However, as technology evolves, traditional incident management processes are being put to the test, and new methods are emerging. One such method that’s transforming the way incident management is handled is GitOps.
The Traditional Incident Management Process
The traditional incident management process usually involves numerous steps, from incident identification and logging to its resolution and closure. The process begins with the detection of an incident, either through proactive monitoring or user reports. Once identified, the incident is logged and assigned a priority based on its impact and urgency.
The next step involves the incident investigation and diagnosis. Here, the incident management team delves into the problem to understand its root cause and come up with a suitable solution. Once a resolution is found, it is applied, and the system is restored to normal operation. The incident is then closed, and a post-incident review takes place to learn from the incident and prevent similar issues in the future.
While this process has been effective for many years, it’s not without its challenges. It often requires manual intervention, which can lead to errors and delays. Moreover, it’s dependent on the expertise of the incident management team, which can vary greatly. This is where GitOps comes in.
What Is GitOps?
GitOps is a paradigm or a set of practices that leverages Git, a widely used version control system, as the single source of truth for declarative infrastructure and applications. With GitOps, the desired state of a system is defined in a Git repository, and any changes to the system must be made through Git.
The power of GitOps lies in its automation. Any changes in the Git repository automatically trigger a pipeline that brings the live system to the desired state, minimizing manual intervention. This makes GitOps a powerful tool for continuous delivery, ensuring that changes are implemented quickly and reliably.
But GitOps is not just about deployment – it’s also transforming the way we think about and handle incident management.
How GitOps Affects Incident Management
Automated Recovery and Rollbacks
One of the most significant ways GitOps impacts incident management is through automated recovery and rollbacks. In traditional IT operations, recovering from a failed deployment or rolling back changes often involves manual processes. These can be time-consuming, error-prone, and require a high level of expertise.
With GitOps, however, these processes can be automated. The Git repository holds the desired state of the system, and the GitOps operator ensures the actual state matches this desired state. If an incident occurs, the system can automatically roll back to the last known good state, drastically reducing downtime and the associated business impact.
Furthermore, this automation also reduces the need for human intervention in incident response. This frees up IT staff to focus on more strategic tasks, such as improving system resilience and addressing the root causes of incidents.

Another significant impact of GitOps on incident management is the enhancement of collaboration. GitOps leverages the power of Git, a tool that many IT teams are already familiar with. This means that teams can use the same workflows they are used to for code management to manage infrastructure and deployments.
By utilizing Git’s features, such as branches and pull requests, teams can collaborate effectively on changes. This can lead to improved visibility and communication during incident management. For instance, an incident response team could create a branch to address a specific incident, ensuring that all changes related to the incident are tracked and reviewed.
This collaborative approach can lead to faster incident resolution. It also encourages a culture of shared responsibility for incident management.
Proactive Incident Prevention
GitOps can also help with proactive incident prevention. By defining the desired state of the system in Git, teams can use code review processes to catch potential issues before they become incidents. This shift-left approach to incident management can lead to fewer incidents and improved system reliability.
Moreover, GitOps encourages a culture of continuous improvement. By treating infrastructure as code, teams can apply the same iterative development practices used for agile development to improve their system configurations. This can lead to fewer incidents over time and a more resilient IT environment.
Integration with Incident Management Tools
Finally, GitOps can integrate seamlessly with existing incident management tools. Many modern tools support GitOps workflows, allowing teams to automate incident response processes and improve their efficiency.
For example, when an incident occurs, a GitOps tool can automatically create a new Git branch. The team can then work on this branch to resolve the incident, with all changes tracked and reviewed in Git. Once the incident is resolved, the changes can be merged back into the master branch, ensuring that the system returns to its desired state.
This integration can also improve visibility into incident management processes. By tracking all changes in Git, teams can easily see what changes were made in response to an incident. This can help with post-incident reviews and continuous improvement efforts.

Potential Drawbacks and Considerations
Dependence on Git
One potential drawback is the dependence on Git. While Git is a robust and widely-used tool, this dependence can create a single point of failure. If the Git repository becomes unavailable, it can disrupt the GitOps workflows and potentially impact incident management.
To mitigate this risk, it’s important to have a robust disaster recovery plan in place for the Git repository. This could involve regular backups and a plan for restoring the repository in case of an outage.
Implementing GitOps can involve a learning curve, particularly for teams that are not familiar with Git or infrastructure as code. This can slow down the initial adoption of GitOps and potentially lead to mistakes in the early stages.
However, these challenges can be overcome with proper training and support. It’s also important to start small, perhaps with a single application or service, and gradually expand the use of GitOps as the team gains confidence and experience.
In conclusion, GitOps can have a profound impact on incident management. By enabling automated recovery and rollbacks, enhancing collaboration, promoting proactive incident prevention, and integrating with incident management tools, GitOps can improve the efficiency and effectiveness of incident management. However, it’s also important to be aware of the potential drawbacks and considerations, such as the dependence on Git repositories and the learning curve, and to plan accordingly.
