What is GitOps?
GitOps is a modern operational framework that applies DevOps best practices to infrastructure automation, using Git as the single source of truth for declarative infrastructure and applications. The approach leverages Git repositories to store the desired state of systems, with automated agents continuously monitoring and reconciling the actual state to match what's defined in version control.
GitOps operates on four core principles:
- Declarative configuration: Systems are described declaratively, focusing on the desired end state rather than the steps to achieve it
- Version-controlled storage: All configuration is stored in Git repositories with complete audit trails
- Automated deployment: Software agents automatically pull and apply configurations from Git
- Continuous reconciliation: Agents continuously monitor for drift and restore the desired state
Why GitOps Matters in 2025
The GitOps market has reached significant maturity in 2025, with over 90% of Kubernetes deployments now managed using GitOps principles. Organizations are increasingly adopting GitOps to address challenges around compliance, security, and scalability in cloud-native environments. The approach has proven particularly effective for managing complex, multi-environment deployments while maintaining security and governance standards.
