Infrastructure up clouds
Infrastructure up, as a concept is simply appending a orchestrator to the existing virtualization stack that we saw before, thereby enabling self-service and increasing agility by automation.
The cloud purists would not even consider these clouds, but there is no denying that they exist. This concept was created to bridge the chasm that was created due to the radical shift of the paradigm of how the applications got created in the service down cloud.
In this kind of cloud, the smallest unit would request and get a virtual machine. There are several Orchestrators that would help provide these functionalities, some of the notable ones include, VMware vRealize Suite (https://www.vmware.com/in/products/vrealize-automation.html), Cisco CIAC (https://www.cisco.com/c/en/us/products/cloud-systems-management/intelligent-automation-cloud/index.html), BMC Atrium (http://www.bmcsoftware.in/it-solutions/atrium-orchestrator.html), to name a few.
The way this is created is by adding a Cloud Orchestrator solution on top of an existing virtualization environment. This provides features such as self-service and billing/chargeback/showback.
The Orchestrator then performs cross domain automation in order to provision virtual machines for the user. As you can see, in this case the life cycle management of the VM is automated, but the idea behind the provisioning has not changed so much. In the event that you decide to delete the VM, more likely than not, all the associated resources also get deleted.

An infra-up cloud is normally characterized by the presence of a workflow Engine, which allows integration to different enterprise systems. It should be no surprise that major infra-up clouds are used in private. There are some exceptions, for example the Vodafone Secure Cloud, which is a public cloud that runs on an infra-up approach.
