VSF template offers a standardized framework for provisioning multiple, similar stacks.
It enables centralized management of stacks at a global or site level, allowing a single
template to configure and maintain multiple stacks efficiently.
Instead of managing each stack individually, changes made to the template are automatically
applied to all stacks that are in sync with it.
A stack may become out of sync with the template if:

1. A user manually modifies the stack configuration directly, bypassing the template.
2. Configuration changes are applied locally within the stack instead of through the central template.
