Private Cloud

With a private cloud, companies provide cloud computing services to a select, defined group of people. This means that it is only possible for authorized users to access the services that are offered via the internet or an internal company network. For this reason – and in contrast to the public cloud – it is also referred to as a private company cloud.

 

How the private cloud works

 

The technological principles behind the different cloud environments are similar. The restricted access to a specific group of users is the first and most decisive difference. Like all other cloud systems, virtualization technologies are also used as the technological basis for this cloud model. The resulting advantage is the ability to combine the physical computing capacities, to draw on them, and to adapt them to the respectively fluctuating requirements of the company. A private cloud therefore scales with the business requirements – that is the second difference: The existing computing capacities are only made available to one company. There is no requirement to share this capacity with other clients, as is the case with other cloud models.

 

Advantages of a private cloud-model

  • Data sovereignty: The services, data and applications of this private company cloud run and are located on your own hardware. This gives you the maximum control over your data.
  • Easily upgraded according to future requirements: In contrast to the public cloud offered by many service providers, this kind of cloud does not have a defined or restricted range of functions. You decide on which applications and services are implemented, and with which software.
  • Secure budgeting: The expected costs can be calculated according to different use scenarios.
  • Flexible infrastructure capacities: greater freedom in the setup and removal of resources
  • Security: The private cloud has a user group that you determine. Unauthorized users are not granted access. You can also determine whether it is possible to find your company cloud via the WWW or not.
  • Compliance: Whether it is legal requirements, regulatory standards, or ethical principles to which your company is committed – as you have the maximum control over your private cloud, you are pretty much “the boss”. This is not the case with other cloud models.

 

Disadvantages of this cloud model

To achieve the advantages referred to above, you are required to be responsible for the operation, management and maintenance of the private cloud, as well as for any adjustments to it. In this respect, it should be clear from the start that your company not only has the required technological know-how. Operating a private company cloud costs time, and therefore money, and should be well thought out and planned. Other models also exist, however. It is naturally the case that you can hire external service providers to do this work; that would make the cloud a “managed” cloud, though. The service provider is responsible for the maintenance, upkeep and customization of the cloud on your hardware. A company cloud can also be provided as a “hosted” private cloud, however. With this model, you do not require any hardware at all. In this case, the external service provider provides the infrastructure, hardware and management of the cloud.
