Git-driven environments: why treating infra as code unlocks consistent builds every time

Git-driven environments address the common issue of inconsistencies between development, staging, and production environments by integrating infrastructure definitions directly into version-controlled code. This approach ensures that each branch in the repository becomes a deployable environment, maintaining parity across all stages of deployment. By treating the Git repository as the authoritative source for both application code and infrastructure, changes are subjected to the same review process, which mitigates environment drift and simplifies rollbacks. This method enhances reproducibility and reduces the complexity typically associated with manually managed configurations like Terraform or Kubernetes. Upsun, a platform implementing Git-driven environments, supports seamless integration with existing CI/CD workflows and offers automated environment provisioning for branches and pull requests. This system not only increases efficiency by providing consistent builds but also allows developers to focus more on feature development rather than debugging environment inconsistencies.
