Hi All,

I would like to ask a question regarding perform patching of VMs in Azure.
We have few VMs running 24 x7 and would like to patch the VM by running of windows update.
Due to reboot might required after windows update so what kind of solution can achieve to avoid any downtime for when perform windows update and reboot the VMs?
I see Azure availability set but this is more for Azure planned maintenance and not for customer planned maintenance usage.
Scale set is configure for threshold seems is not suitable also.

May i know who you all patching your Azure production VMs?

Any feedback will be appreciated.

Regards,

    Enabling automatic VM guest patching for your Azure VMs helps ease update management by safely and automatically patching virtual machines. More details and supported OS are here : automatic-vm-guest-patching

    In this way azure will handle the automatic patching once in a month and need a reboot also as and when needed. While saying that, not the reboot requirement here too. The zero downtime solution can be implemented only with a supported application design which can handle the downtime situation by switching the application access to a different VM, which is planned to patch in a different schedule
