No tools IaC tools I know of including Pulumi, allow to describe evolutions for infra. Simple use case - deploy canary instance, check it's health, scale down canary instance, update main pool of instances. In other words, there is no way to express sequence of changes of the same object in the single run of IaC tool. We are forced to wrap IaC tools in layers of bash to simulate it.
