Azul-Verde Despliegue is a software deployment strategy designed to reduce downtime and risk by running two identical production environments. These environments are referred to as the blue environment, which is the live environment currently serving users, and the green entorno, que es el área de preparación para la nueva versión de la aplicación.
En un despliegue azul-verde típico, cuando una nueva versión del software está lista, se despliega en el entorno verde. Este entorno se prueba completamente mientras el entorno azul continúa manejando todo el tráfico de usuarios. Una vez que se verifica que la nueva versión funciona como se espera, se cambia el tráfico del entorno azul al entorno verde. Este cambio puede hacerse de forma instantánea, resultando en un tiempo de inactividad mínimo para los usuarios.
One of the key advantages of this strategy is the ability to quickly roll back to the previous version (blue) if any issues arise in the new version (green). Since both environments are fully operational, reverting back to the previous version can be done without significant interruption. Additionally, this method allows for more straightforward testing and validation of the new release, as it can be done in a setting that closely replicates the production environment.
La implementación Azul-Verde es particularmente útil en entrega continua pipelines, where frequent updates are necessary. However, it does require maintaining two separate environments, which can increase infrastructure costs and complexity. Proper monitoring and management are essential to ensure the smooth transition between environments and to handle any potential issues that may arise during deployment.
