The cloud is now a backup mode widespread in businesses. Even if there is still a long way to go, its use is tending to become widespread within small and medium-sized enterprises (SMEs).
Earlier we weighed the advantages and disadvantages of hybrid and public cloud. Now, it’s about time to shed some light on the pros and cons of private cloud, so that you can opt for the cloud solution most suited to your operating modes.
Private cloud refers to cloud computing services offered to a single organization in isolation from others. Unlike the public cloud, the private cloud provides a dedicated environment, accessible only by the organization or the people who have access to it.
In this model, the company is responsible for planning, implementing and managing all cloud technology. This can be done with a company-allocated server or by a third party.
The private cloud can be offered in two models:
- Platform as a service (PaaS)
- Infrastructure as a service (IaaS)
The private cloud brings all the characteristics of cloud computing, but without sharing space with other customers. It is a widely used solution for businesses that seek more control and customization in their system.
Those who migrate to the private cloud service pay strictly for the resources they hire. It is considered that the private cloud will attract many organizations enticed by the benefits it provides.
The tailor-made side of the private cloud allows the company to specifically choose the hardware on which its infrastructure will be based and to seek a high level of performance to meet business constraints.
As cloud service providers offer the use of virtual servers, security and monitoring services, as well as upgrades and support, much of the company’s IT spending is eliminated, which implies more capital to redirect you to the core business of the organization.
Another advantage common to all types of cloud, migrating to cloud computing allows the business to get rid of its physical limitations – files, software and systems can be accessed anytime, anywhere.
In the private model, this availability may be even higher. The public cloud has to deal with a large number of concurrent clients, so periods of instability and downtime are more frequent, disrupting productivity across the enterprise.
Because unique infrastructure is built around your needs, it is much easier to control delivery and ensure it is available as long as possible.
The configuration of the equipment, storage units and network is defined so as to precisely meet the specifications of IT security managers and the compliance constraints of its sector of activity. The private cloud offerings allow businesses direct control over their data and minimize risk in terms of IT security.
Data stored in a private cloud is available in a protected environment, which is dedicated solely to your business. This detail alone ensures greater data security and better control over your environments.

In private cloud, there is greater control over data, especially sensitive data such as financial reports and customer contacts, as they are hosted internally but it also has some limitations to it. Below mentioned are some disadvantages of private cloud.
One disadvantage is the need for physical space and periodic hardware or software expenses. Therefore, this type of cloud computing model tends to be more expensive and is mostly suitable for large companies.
In addition, this cloud mode will be less reactive in the event of a brutal data load.
Setting up this infrastructure represents a higher cost and is time-consuming as compared to public cloud service. In this case, the company could rely on a hybrid cloud in order to gain scalability and consume resources for use on public cloud environments.
The private cloud can only be extended from internal hosted resources. In order to maintain deployment, the organization requires qualified expertise.
In addition, it is very difficult to deploy on a global scale. Also, it requires much more resources and takes longer to reach its full potential.
Those in the process of migrating to the virtual environment should keep in mind that in the public cloud, all provider equipment, applications, and infrastructure are shared by companies around the world.
Often millions of users, have access to the same servers at the same time, resulting in problems such as low availability.
Another issue is that unrestricted third-party access to the structures that will allocate your most important business data can ease intrusions, endangering the entire security of your organization.
On the other hand, those who opt for the private cloud can avoid the headaches mentioned above.
