Load Balancer and Public IP Upgrade from Basic to Standard - With Fabric Cluster

Ali Ahmed 0

Hi there,

We understand that we need to upgrade the load balancer and public IP from Basic to Standard SKU.

Our setup with VMSS currently hosts 5 nodes for the Fabfic Cluster Service. Additionally, the production system is a high-availability application, so ideally, we would prefer to avoid any downtime.

I watched the video demonstrating scenarios where the upgrade was performed. I tested the process in our staging environment, and it resulted in over 15 minutes of system downtime.

The video mentioned that no downtime could be achieved by adding a new node type, but it didn’t provide further explanation or a demo. Would it be possible to create a detailed guide and demo video to help us successfully execute this upgrade for a production environment?

Thank you!

I saw the answer, but it didn’t address my question. If you watch the video, there’s a clip at the end discussing the use of different node types to prevent or minimize downtime. I was hoping for more information on that particular scenario, as the Service Fabric Cluster will take a long time to process. For example, when I set up the dev environment, it took nearly 3 hours.

Hi @Ali Ahmed,
Thank you for your patience.

We understand that you are planning to upgrade your load balancer and public IP from Basic to Standard. During the upgrade, you may experience minimal downtime due to potential misconfigurations and issues while disassociating the public IP from the load balancer.

Note: Therefore, we recommend planning the upgrade during non-business hours to avoid any impact on your production environment.

Kindly check the below document for more details:

Hi Ali Ahmed,

Thank you for reaching out to the Microsoft Q&A platform.

Make sure you must the have backup before starting the activity

The upgrade normally takes a few minutes for the script to finish. The following factors may lead to longer upgrade times:

Complexity of your load balancer configuration

Number of backend pool members

Instance count of associated Virtual Machine Scale Sets or Virtual Machines.

The Basic Load Balancer needs to be removed before the new Standard Load Balancer can be created, there will be downtime to your application.

Please find the below documentations for your reference:
