Private Cloud vs Public Cloud

April 10th, 2012

Private Cloud vs Public Cloud blog A private cloud also known as an internal cloud or a corporate cloud refers to proprietary computing architecture that provides hosted services behind a firewall to a limited number of people. It is only accessible to a single company as opposed to being divided amongst different clients. A public cloud on the other hand makes use of the cloud computing model in which resources such as storage and other applications are made available to the general public via the internet by a service provider.

Here we look at some of the biggest benefits of running a private cloud. Given the economic environment, IT organisations will continue to experience many challenges. This means that many businesses are likely to actively seek other ways of running their applications and the public cloud could be one such way. By looking at the more appealing attributes of cloud computing, you can determine how to offer the same functions within your private cloud that will ultimately be more secure for your business.

Most businesses are already running virtual servers that are backed by data storage. Indeed, many more could be using advanced virtualisation in which case resources are virtualised across servers, storage and network. Such businesses are probably closer to private cloud operation than they think. Since most of the attributes that are derived from advanced virtualisation are similar to those in a private cloud, then this is surely the way to go. Some of these benefits are:

  • Standardisation
  • Agility
  • Added efficiencies
  • Elasticity
  • Service oriented

Building a private cloud will ultimately be cheaper than using a public cloud. Although a public cloud may look cheaper when you are starting off, with time, a private cloud will prove more efficient and cost effective. Also, with a good plan for expansion, you are likely to realise more benefits from an internal cloud than you may think possible.

A private cloud allows for sharing of infrastructure amongst business applications. On the other hand, a public cloud may require great maturity before it can actually offer this shared infrastructure. A private cloud therefore enables business owners to easily access the shared infrastructure while at the same time limiting the risks that they are exposed to.
