Reimaging vs Upgrade options

Question

Thursday, October 17, 2019 6:15 PM

In looking at instnaces within a VMSS there are the Connect, Start, Restart, Deallocate, Reimage and Delete buttons in Azure. What is the difference in Reimaging a VM in a scale set versus Upgrading a VM in a scale set? Thanks!

For each ScaleSet you have the following options

Upgrading will apply any changes that were applied to the scaleset as a whole. So for example, if you apply a custom script extension to VMSS1 you need to update the VMSS instances in order for that custom script to actually be applied. 

If you select reimage, it will remove the VMSS instance and replace it with a brand new one. This can be used if you are having issues with a single instance and want to essentially delete it and redeploy it.
