Terraform is more granular. The upgrade of an application means deployment of new instances. For a typical web app, this may mean a load balancer running on the machine in a public subnet, and one or more back-end applications running on private subnets. A variety of actions can be automated with this approach. Terraform provides descriptive (declarative) way of defining the target configuration, where it can work out the dependencies between configuration elements and apply differences without re-provisioning the entire cloud stack.
