GitOps vs. DevOps – Part 02: Which one’s for you?

In the previous blog, we discussed GitOps and DevOps, two revolutionary methodologies that are reshaping the software development industry. GitOps excels in cloud-native environments and automated deployments, whereas DevOps places a stronger emphasis on teamwork and communication to deliver software more quickly. Both have the same objectives of effectiveness, automation, and collaboration, which makes them complementary. Organizations can improve stability, reduce time to market, and accelerate feedback cycles by integrating GitOps with DevOps.  

In this blog, we’ll delve into adoption considerations of GitOps and highlight their suitability and challenges like scalability, learning curve, infrastructure transitions, and more. We’ll have a look at how Ozone’s trigger-based approach solves these GitOps challenges and offers much more. 

Adoption Considerations: Navigating GitOps vs. DevOps

Are you interested in learning more about the specific fields or applications of GitOps or DevOps? 

We’ll examine both methodologies’ use cases and adoption issues. We’ll also discuss the sectors or situations where each approach excels, things to consider when choosing, difficulties in switching between GitOps and DevOps, and case studies of businesses that have successfully applied these methodologies.

GitOps and DevOps suitability: Adapting Methodologies to Sectors and Scenarios

GitOps is a more specific idea that frequently forms a part of the DevOps philosophy as a whole. GitOps and DevOps can be used in a variety of settings and industries, though their applicability may vary.

GitOps and DevOps can be used in various settings and industries. DevOps is widely used in software development, tech startups, and e-commerce because of its focus on teamwork, communication, and cross-functionality. It facilitates innovation, shortens the time to market, and streamlines software delivery. 

On the other hand, GitOps excels in cloud-native environments, containerized applications, and scenarios requiring infrastructure as code, thanks to its focus on automated deployments and declarative configurations. The inherent reproducibility provided by GitOps may be advantageous to sectors like fintech, healthcare, and telecommunications.

Future Trends in GitOps and DevOps Adoption

  • Greater Integration and Convergence: GitOps and DevOps will become more integrated and similar. Organizations will look to combine the benefits of both methodologies, combining GitOps’ declarative configurations and automation capabilities with DevOps’s collaboration and communication features. This integration will make the pipeline for delivering software more streamlined and effective.
  • Shift to Cloud-native and Serverless Architectures: As businesses adopt cloud-native and serverless architectures more frequently, there will be an increase in demand for practices like GitOps. These methodologies offer the techniques and tools required to manage complex, changing infrastructures. In the future, GitOps and cloud-native technologies will be even more integrated, allowing businesses to deploy applications in these environments more quickly and reliably.
  • Enhanced Security and Compliance: In the future, organizations will continue to prioritize security and compliance. GitOps and DevOps will develop to include strong governance practices and security measures. This entails implementing compliance automation, integrating security as code, and ensuring secure access controls and auditing capabilities. 

Artificial Intelligence and Machine Learning: As AI and ML become more prevalent, GitOps and DevOps will evolve to meet the particular needs and requirements of AI/ML-driven applications. In the future, specialized tools and frameworks will be created to make the GitOps and DevOps pipelines more effective at managing, monitoring, and deploying AI/ML models.

Choosing GitOps: Important Things to Take into Account

GitOps vs. DevOps should be chosen for your organization based on the following factors:

  1. Project Requirements: Consider the requirements specific to your project, such as the applications’ nature, scalability needs, infrastructure complexity, and desired deployment speed.
  1. Team Structure and Culture: Evaluate your team’s expertise, familiarity with version control tools like Git, and readiness to adopt automated processes and collaborative techniques.
  1. Deployment Environment: Consider your deployment environment’s characteristics, such as whether it is a hybrid, on-premises, or cloud-native infrastructure.
  1. Compliance and Security: GitOps and DevOps may take different governance and security considerations approaches, so look into your project’s compliance and security requirements.

GitOps Challenges: 

When attempting to integrate GitOps into an existing DevOps environment, adoption issues arise. Coordination issues between GitOps and a well-established DevOps methodology may arise when they are combined. Careful planning and teamwork may be necessary to coordinate the current DevOps workflows with GitOps declarative configurations and automated deployments. To avoid miscommunication and maximize the advantages of both methodologies, it is also essential to ensure seamless communication and understanding between DevOps and GitOps practitioners.

There are several challenges and considerations to take into account when you consider GitOps:

  1. GitOps scalability:  In the context of GitOps and ArgoCD, pipelines are closely mapped to a specific repo, project, and action. This becomes an issue with microservices at scale since you will need multiple pipelines to deploy multiple microservices from separate repos across multiple clusters. This gradually leads to pipeline sprawl which is a nightmare for DevOps teams to deal with and where GitOps does more harm than good in the long run.  
  1. Learning Curve: Moving to GitOps, which introduces declarative configurations and Git-based workflows, may involve a learning curve when adopting new methodologies.
  1. Infrastructure and Tooling: Consider the existing infrastructure and tooling in your company. Implementing new tools and establishing infrastructure-as-code procedures may be necessary to transition to GitOps.
  1. Team Training and Support: During the transition, ensure that teams receive the proper training and support, as they might need to acquire new abilities and information to adopt the methodology of choice successfully.
  1. Lack of Real-Time Collaboration: For configuration and deployment, GitOps heavily relies on Git as its source of truth. Using Git for every configuration change, however, might be laborious in circumstances where real-time collaboration is required. GitOps may need to be used in conjunction with other tools or techniques to effectively collaborate on infrastructure and application changes in real-time.

There are specific use cases and adoption considerations for both GitOps and DevOps. While GitOps excels in cloud-native environments and scenarios requiring infrastructure as code, DevOps is frequently used in software development, startups, and e-commerce. 

GitOps XXL:  Marrying traditional automation with Tekton’s reusability

The Achilles heel for GitOps has always been with its scalability. Pipelines are alway closely mapped with one specific repo for one specific action and for one specific project. This approach might have been suitable a couple of years ago with cloud becoming the focus. However, it lags big time in the era of microservices, where you have multiple projects and services running within them. You need flexibility of where you want your pipelines to run and also scale on-demand. It is unfortunate that teams continue haphazardly scaling their pipelines to a few thousands in numbers and are now looking at a pipeline management disaster waiting to happen. 

The way Ozone solves this is through Tekton triggers and reusability. You can configure just one pipeline template for identical microservices, and map the same against different microservices, repos, clusters, and projects. With Tekton triggers, you can either use a webhook linking your repositories, or schedules, to automate a pipeline trigger. You can even extend this feature to trigger complex releases as well, making release management a piece of cake.  This way, Ozone offers a workflow that is much more advanced than traditional GitOps, giving you the flexibility to automate deployments at scale with unlimited flexibility. For more information on reusable Tekton pipelines on Ozone read our blog on Ozone pipeline studio. 

Here’s how simple it is to add a trigger on Ozone: 

Triggers can be added in the form of webhooks and schedules. This is how a webhook creation looks like:

Ozone supports webhooks for GitHub, Jira, GitLab, Bitbucket, Slack, Azure Cloud Registry, Docker Hub, Harbor or any generic webhooks. 

You can also create a schedule by selecting the time as to when you would like a pipeline or a release to be triggered.
