Private Cloud: what is it and what to know about it.

Private cloud is a type of cloud computing that delivers similar advantages to public cloud, including scalability and self-service, but through a proprietary architecture. Unlike public clouds, which deliver services to multiple organizations, a private cloud is dedicated to the needs and goals of a single organization.

As a result, private cloud is best for businesses with dynamic or unpredictable computing needs that require direct control over their environments, typically to meet security, business governance or regulatory compliance requirements.

What is cloud computing?

Cloud computing is an information technology (IT) paradigm that enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet.

Private, public and hybrid cloud

A public cloud is where an independent, third-party provider (Amazon Web Services)  or Microsoft Azure, owns and maintains compute resources that customers can access over the internet. Public cloud users share these resources, a model known as a multi-tenant environment.

By comparison, a private cloud is created and maintained by an individual enterprise. The private cloud might be based on resources and infrastructure already present in an organization’s on-premises data center or on new, separate infrastructure. In both cases, the enterprise itself owns and operates the private cloud.

A hybrid cloud is a model in which a private cloud connects with public cloud infrastructure, allowing an organization to orchestrate workloads across the two environments.

Pros and cons of private cloud

Private clouds are often deployed when public clouds are deemed inappropriate or inadequate for the needs of a business. In other cases, the risk of hosting a critical workload in the public cloud might exceed an organization’s risk tolerance, or there might be security or regulatory concerns related to the use of a multi-tenant environment.

However, private clouds also have some disadvantages. For exapmle increased automation and user self-service, can bring some complexity into an enterprise.  As a result, an organization might have to adjust or even increase its IT staff to successfully implement a private cloud.

Another potential disadvantage of private clouds is cost. When a business owns its private cloud, however, it bears all of the acquisition, deployment, support and maintenance costs involved.

Major private cloud vendors

A private cloud is commonly deployed on premises in much the same way a business would build and operate its own traditional data center. However, an increasing number of vendors offer private cloud services that can bolster or even replace on-premises systems.

Some of the largest players  include Hewlett Packard Enterprise, VMware, Dell EMC, Oracle and Ibm.

Red Hat has also emerged as a major vendor for private cloud deployment and management with a range of platforms.
