Survey and Evaluation of Blue-Green Deployment Techniques in Cloud Native Environments

Today, the cloud computing customers assume that the services or applications consumed from the cloud are always on, highly available for uninterrupted utilization. The requirement then for the service providers becomes to minimize the planned maintenance windows duration in order to reduce their repercussions on the service availability for the consumers. We evaluate in this paper the continuous deployment methodology called Blue/Green deployment which aims to support zero maintenance windows, and consequently to avoid any interruption to the end users. Our experiments analyze the most common Blue/Green deployment techniques in the industry, measure and normalize their behavior, and aim to identify the approach with the best performing continuous delivery as compared to the available technologies.
