5 things a private cloud is NOT

By Brandon Butler, Network World |  Cloud Computing, Gartner, private cloud

"IaaS only provides the lowest-level data center resources in an easy-to-consume way, and doesn't fundamentally change how IT is done," he says. The platform as a service (PaaS) layer, he says, is where organizations can create customized applications built to run on cloud infrastructure. PaaS comes in public or private flavors as well, having the application development service hosted either in your own data center or in a dedicated environment from a provider.

It may not always be private

Private cloud is the natural first step toward a cloud network for many organizations. It provides access to the benefits of the cloud - agility, scalability, efficiency - without some of the security concerns, perceived or real, that come with utilizing the public cloud. But Bittman predicts that as the cloud market continues to evolve, organizations will open to the idea of using public cloud resources. Service-level agreements and security precautions will mature and the impact of outages and downtime will be minimized. Eventually, Gartner predicts that the majority of private cloud deployments will become hybrid clouds, meaning they will leverage public cloud resources. Meaning your private cloud today, may be a hybrid cloud tomorrow. "By starting with a private cloud, IT is positioning itself as the broker of all services for the enterprise, whether they are private, public, hybrid or traditional," Bittman says. "A private cloud that evolves to hybrid or even public could retain ownership of the self-service, and, therefore, the customer and the interface. This is a part of the vision for the future of IT that we call 'hybrid IT.'"
