For some good reasons I need to have a cloud-init process and a custom script extension on a VMSS. The cloud-init process is intended to bootstrap base VM configuration such as hardening tools and son on while the custom script is meant to deploy application specific code.
My question is if I both in which sequence do they run? does the cloud-init process runs first and the custom script extension runs after? Also, if I have multiple extension on my VMS such as the DSC extension, with custom scripts and monitoring agent. do they all run at the same time?

The cloud-init process will run first. Then the custom script will run after.

No, they will run one by one. See the VM extensions sequence in VMSS.
