What is Private Cloud Computing?
The Private Cloud is essentially a Cloud Infrastructure that operates solely for a single organizationor where the service access is limited to a specific group of people. Private Cloud Computing is comprised of networking, server hardware (which usually provides server virtualization), storage and management tools. This is most often managed internally but also can be hosted externally by a Managed Service Provider (MSP), which is then known as a Virtual Private Cloud.
Cloud computing offerings started on public clouds, but aren’t limited to them. Establishing private clouds is one of the most important current trends to modernize enterprise IT. Organizations are looking at private clouds as an approach to protect their investments and control core assets while taking advantage of cloud technologies. Another motivation for the increasing popularity of private cloud solutions among larger IT organizations are enterprise requirements, which often exceed the functionality offered by public cloud providers and their standard services, especially in areas such as security and compliancy, reliability, control and customization.
Experience has shown that enterprise cloud strategies that have an infrastructure-centric viewpoint and focus only on Infrastructure as a Service (IaaS) solutions proved to be insufficient to unveil the benefits of cloud computing technologies. The IaaS cloud model abstracts the underlying infrastructure but falls short when it comes to addressing complexities imposed by the software solution stack. Many enterprise IT organizations started to consider other cloud services models such as Database as a Service (DBaaS), Mobility as a Service (MaaS) and, ultimately, Anything as a Service (XaaS) to provide:
- A standardized foundational solution stack to run business applications
- Consistent, automated application management and deployment
- Commoditized platform services that can be consumed and shared by business applications via Application Program Interface (API) calls.
