Como administrador de nube, puede aprovechar los recursos de VMware Avi Load Balancer para construir su infraestructura. También puede utilizar aplicaciones auxiliares de asignación para proporcionar lógica de asignación para sus recursos de Avi Load Balancer.
Antes de comenzar
Antes de comenzar con cualquiera de los ejemplos de plantilla, deberá crear la cuenta de nube de Avi Load Balancer en Automation Assembler, crear un proyecto y agregar la zona de nube. Para obtener instrucciones, consulte Cree una cuenta de nube de VMware Avi Load Balancer.
Plantilla de LBaaS simple
Esta plantilla de ejemplo muestra cómo se puede crear un servicio virtual, un grupo y recursos de IP virtuales con entradas mínimas.
Todos los recursos de Avi Load Balancer utilizados en este ejemplo hacen referencia a construcciones de Avi Load Balancer que apuntan a la controladora de Avi Load Balancer.
No hay máquinas ni servidores aprovisionados en esta plantilla. Se obtiene la lista de servidores, que se pueden actualizar continuamente.
El valor predeterminado de la plantilla es un grupo vacío, pero el formulario y la entrada están configurados para que se puedan introducir direcciones IP reales y se cree un grupo normal.

Plantilla de LBaaS avanzada
Esta plantilla de ejemplo muestra cómo se puede crear un servicio virtual, un grupo y recursos de IP virtuales conectados a una red existente junto con una aplicación auxiliar de asignación de zona de nube. Además, el grupo está configurado con el monitor de estado HTTP del sistema.

Plantilla de servidores web simples
Esta plantilla de ejemplo muestra cómo se pueden crear un servicio virtual, un grupo, una IP virtual y dos recursos de máquina virtual de servidor web conectados a una red existente. El grupo está configurado para supervisar el puerto 80 mediante el algoritmo Round robin (por turnos).

Plantilla de servidores web avanzada
Esta plantilla muestra cómo se puede crear un servicio virtual, un grupo y recursos de IP virtuales conectados a una red existente junto con una aplicación auxiliar de asignación de zona de nube. Además, se crea y configura un monitor de estado y un perfil de persistencia de aplicaciones en el grupo. Por último, los grupos de seguridad se enumeran por etiqueta y se les agregan los servidores web de máquina virtual.
