The new role for the private cloud – it’s not what you think

Grazed from CloudComputingNews. Author: David Linthicum.

Private cloud was popular in the early days of cloud computing when enterprises struggled with security and control issues. These days, public cloud dominates, as revealed in the recent “State of the Cloud Study” from RightScale. The reasons for the growth of public clouds are pretty clear, including low operating costs, instant scalability, and the ability to better support changing businesses. However, the private cloud still has a place in IT, and understanding what’s about to emerge in the private cloud space will give you a better focus on this pattern of cloud architecture.

Private clouds are being leveraged as points-of-control or interfaces into public clouds. These emerging hybrid clouds or multi-cloud architectures use a tiered approach where the private cloud (tier 1) links to public cloud services (tier 2), and those looking to access cloud services do so using the private cloud services as the primary interface. Then, as needed, the private cloud leverages the public cloud services…

An example would be a private cloud that runs on an MSP for an enterprise. While the private cloud provides cloud services such as storage and compute using the native interface of the private cloud software, these services are supported with resources that run in the MSP’s public cloud…
