OpenStack-based solutions from Morphlabs, Piston Cloud, Cloudscaling, or Rackspace Cloud Builders. 
They aren’t choosing solutions built from the virtualization layer up or built to preserve the traditional 
enterprise IT management tools that are in place today. It’s not that solutions built from the latter aren’t 
fully capable of being clouds, just that developers don’t know these vendors and don’t see their solutions 
as aligned with the public clouds with which they want to integrate. The new cloud administrators are 
starting fresh with new solutions that are designed to integrate with the public cloud first and the rest of the 
enterprise second. For more information on traditional and cloud native applications, see the February 21,

 Traditional enterprise applications and cloud-native applications differ in design and requirements. 
Generally, applications that sit atop VMware vSphere are traditional Windows and Linux applications that 
live within a static configuration of resources. They don’t scale out, they aren’t componentized web services, 
and they tend to have a fixed and permanent footprint. And these applications never get turned off (at least 
not on purpose). They were most likely built and configured for purpose and, in most cases, were put into 
virtual machines (VMs) that mimicked the physical server configuration they ran on. Cloud native apps 
are elastic or transient. The best-fit applications in the cloud are designed to scale out, are componentized 
in construction, intercommunicate via web services, and are designed to fail. They are optimized for cloud 
environments and built under the assumption that they will run on commodity infrastructure and activate 
cloud economics. Clouds encourage developers to adapt to their capabilities and services, which are highly 
standardized, as they are shared among many customers. For more information on traditional and cloud 
native applications, see the February 21, 2013, “
