Azure Blue/Green Deployment

Azure Blue/Green Deployment is a deployment strategy that minimizes the risk associated with deploying updates by running two identical production environments—Blue and Green. In this approach, one environment (e.g., Blue) runs the current version of the application, while the other (e.g., Green) runs the new version. Once the new version is tested and validated in the Green environment, traffic is switched from the Blue environment to the Green environment, effectively making the new version live. This strategy allows for a smooth transition with minimal disruption and provides a rollback option if issues are encountered. Azure Blue/Green Deployment enhances deployment reliability and reduces the impact of potential failures by ensuring that users always have access to a stable version of the application.
