Combining deployment and monitoring into a single interface and application programming interface (API) radically reduces complexity, improves efficiency, and allows Development and Operations to truly coalesce in the same continuous integration/continuous deployment (CI/CD) pipeline-driven environment.

Another key distinction is that the GitOps tooling constantly watches the state of the application and infrastructure, as well as checking for any new code or configuration changes. If an approach is not 100% declarative, it’s not GitOps. It’s worth emphasizing that GitOps – unlike other infrastructure-as-code methodologies – is by definition 100% declarative. The deployment and management of the application and infrastructure is largely automated, enabling simple versioning and rollbacks. In GitOps, users declaratively define an application and its underlying infrastructure in Git. A GitOps Primerįor the uninitiated, GitOps is a methodology for managing infrastructure and applications that uses Git as the central repository for instructions and the single source of truth. With the adoption of proper GitOps, you can actually “shift left” with a fully declarative process for defining resources and a fully automated process for deploying, modifying, maintaining, and monitoring them to keep systems running in the desired state without the need to manually check for dependencies and remediate any issues.

By that, I mean declarative all up and down the stack, even at the application layer – without manual processes but with continual drift detection. Why? GitOps is the moment we cross the Rubicon and move fully into the realm of 100% declarative – infrastructure-as-code the way we all hoped it would be. While it’s easy to write off GitOps as just the latest flavor-of-the-month, I see it as a potential sea change and signal moment in how we build the technology stacks that run modern applications.
