Blue-Green deployments are aprogressive delivery patternwhere two environments exist: Blue (current version) and Green (new version). The new version is deployed in parallel, and once validated, traffic is switched over from Blue to Green.

“Blue-Green deployments provide zero-downtime releases by running two production environments: one active and one idle. A new version is deployed to the idle environment, tested, and when ready, traffic is switched to it.”

Thus, the correct description isA.

In GitOps, Continuous Deployment (CD) follows after Continuous Integration (CI). CI is responsible for building and testing application code, while CD automates the delivery and deployment of these changes into runtime environments. The Git repository serves as the single source of truth, and when CI merges new changes into the main branch, CD reconciles the state of the environment to match what is declared in Git.

“GitOps builds on the principles of DevOps by using Git as the source of truth for declarative infrastructure and applications. CI pipelines handle the integration and testing of code, and CD pipelines or agents automatically reconcile the desired state in Git with the actual state in the cluster.”

This shows that CD is triggered after CI to handle deployment automation, ensuring systems remain in sync with what is declared in version control.

The reconciliation loop is a fundamental GitOps principle. It continuously compares thedesired state(stored in Git) with theactual state(running in the system). When a divergence (drift) is detected, the reconciler automatically corrects the system to match the desired state.

“The reconciliation loop ensures the system is continuously converging toward the declared desired state. Whenever the actual state deviates, the loop reconciles the system to match the desired state.”

Thus, the correct answer isC.

Infrastructure as Code (IaC)is a foundational practice in GitOps. It involves managing and provisioning infrastructure throughdeclarative, machine-readable filesrather than manual processes or GUIs. IaC ensures consistency, automation, and repeatability across environments.

“Infrastructure as Code defines and manages infrastructure through code files stored in version control. This enables automation, reproducibility, and immutability in infrastructure provisioning.”

Thus,Dis correct.

In GitOps, thepull-based modelcontinuously reconciles the actual state with the desired state. This makes it resilient to drift, since reconciliation runs regularly. In contrast,event-driven systemsonly reconcile when an event occurs (e.g., a webhook), which makes them more prone to drift if changes happen outside those events.

“A pull-based reconciliation loop ensures continuous alignment with the desired state. Event-driven reconciliation, triggered only on events, risks system drift if changes occur outside those triggers.”

Thus, the correct answer isD.
