(1) upload the updated script to SA1 (2) modify the custom script extension setting on vmss1: one pool is production pool, another pool is testing pool, only vm in production pool will apply new script (3)modify the load balancer, direct 90% traffic to production pool while direct 10% traffic to testing pool.
By adjusting the load balancer rules or backend pool, you can direct traffic to specific VM instances running the modified version, enabling targeted testing without affecting all users.
A. Modify the load balancer settings of VMSS1. ✅ Correcto → Para que solo parte del tráfico vaya a la nueva versión y el resto siga en la actual, necesitas jugar con el load balancer / backend pools de la scale set. Eso permite que solo unos usuarios (canary testers) reciban la versión nueva. B. Redeploy VMSS1. ❌ Incorrecto → No quieres recrear toda la scale set (costoso y rompe el objetivo de “minor change testing”). C. Upload a custom script file to sa1. ✅ Correcto → La nueva versión de WebApp1 se instala con un nuevo script. Para actualizar, debes cargar el script modificado a sa1. D. Modify the Custom Script extension settings of VMSS1. ✅ Correcto → Después de subir el nuevo script, necesitas apuntar la extensión hacia él para instalar la versión nueva. E. Update the configuration of a virtual machine in VMSS1. ❌ Incorrecto → Con VMSS no trabajas VM por VM manualmente, sino con extensiones y configuración centralizada.
