Beneficios¶

Todas las aplicaciones de acceso al clúster a través de una sola dirección IP. La topología de la base de datos de clúster enmascarado detrás HAProxy.
Es posible añadir o eliminar nodos de base de datos sin ningún cambio en las aplicaciones.
Una vez que el número máximo de conexiones de bases de datos (MySQL) alcanzó, HAProxy colas nuevas conexiones adicionales. Esto es una clara forma de peticiones de conexión de base de datos de estrangulamiento y logra protección de sobrecarga.
