How a team of 15 developers deploys 4200 times per Month using the Preview Environments

In a dramatic transformation, a company managed to increase its deployment frequency from 20 to 850 times per week within just 30 days by adopting Qovery's "Preview Environment" feature. This feature allows every pull request to be tested in a full replica of the production environment, which is isolated and ephemeral, thus boosting confidence in changes and avoiding production outages. By utilizing multiple AWS accounts and isolated Kubernetes clusters, the company achieved better separation between production, staging, and development environments, resulting in enhanced development performance and structure without sacrificing productivity. This new approach led to an impressive average of 9 deployments per day per developer, significantly outperforming industry benchmarks.
