Since the inception of Cloud Computing the world of application development has been revolutionized. In a nutshell, “Cloud Computing” refers to the provisioning of computer resources and service over the internet. Resources and services like computational assistance, data storage, connection, load balancing for high scalability, networking between different clusters associated with the cloud system.
Stick to the end to learn all about the private cloud. But, before starting our journey let’s have a look over the points to be covered.
Points to be covered:
If you are an absolute beginner in the field of Cloud Computing, check out our Youtube video on Introduction to Cloud Computing.
What is a Private Cloud?
Let’s begin our journey of learning about the private cloud. In this first section, we will empower you with the knowledge of the private cloud with which you will be able to answer the frequently asked questions viz. “What is Private Cloud? Its working, and architecture”.
The private cloud is also known as Internal Cloud or Corporate Cloud. It refers to a model of cloud computing which carries out computational tasks solely for an organization or an individual.
- The infrastructure of the private cloud is situated either at the organization’s own data center facility or the third-party vendor.
- The private cloud uses the concept of virtualization to bind up the different components utilized during the computational tasks.
- The private cloud is only available for the end users within the organization’s firewall, which means that unlike the public cloud, the whole cloud system is isolated from the access of other users.
- The concept of the private cloud was introduced to provide enhanced security to the end users within the firewall and dedicated infrastructure for the organization itself.
- After the introduction of the private cloud, it was easy for the organization to check on the sensitive and operational data of the organization and associated entities.
- Some of the renowned examples of private clouds are HP Data Center, Elastra Private Cloud, Ubuntu, Microsoft, and many more.
- Based on the types of application, a private cloud can be divided into two categories: the first one is based on IaaS (Infrastructure as a Service) and the other one on PaaS (Platform as a Service).
- Private cloud architecture possesses a very strong architecture. Data centers are built using SDN (Software Defined Networking) and VMs (Virtual Machines).
Benefits of Private Cloud
Now let’s look at the benefits of private cloud.
Check out the below-mentioned pointers to have an in-detailed explanation of the benefits provided by the private cloud. Furthermore, these points will also state the reasons why we use a private cloud.
- More Data Control – With so many restrictions and a very low number of end users for the infrastructure it becomes really easy to control the data and the flow of information.
- Enhanced Security and Privacy – The infrastructure of the private cloud is isolated only users within the firewall of the organization are allowed to access the cloud.
- Improved Performance – The private cloud has dedicated servers and associated infrastructure which only works for the isolated system, and because of this the private cloud shows better performance.
- Highly Customisable – The private cloud is highly customizable because of private cloud architecture and personalized development. As the whole system is owned by the organization adoption of the most suited services is done.
In the upcoming section, we will discuss the differences between the private cloud and the public cloud.

Private Cloud v/s Public Cloud
Private and public clouds are antonyms. A public cloud refers to a type of cloud computing model that provides the needed services to organizations and individuals over the public internet whereas the private cloud does the opposite.
Let’s see some of the differentiating factors between these two different types of cloud computing models.
| Private Cloud Computing Model | Public Cloud Computing Model |
| It is a type of cloud model where the infrastructure is only shared with the end users within the organization’s firewall. | It is a type of cloud model where the infrastructure is shared with multiple users ranging from an organization to an individual. |
| It shows single-tenancy and the network used is private. | It shows multi-tenancy and the shared network is public. |
| The scalability of the private cloud is very limited with very high reliability because of the restrictions. | The scalability of the public cloud is very high with moderate reliability because there are no restrictions. |
| The private cloud needs more finances with more maintenance and skilled manpower. | The public cloud needs a lesser amount of money as compared to the private cloud, less maintenance, and not much-skilled manpower is required. |
| The performance of the private cloud is very high because of its dedicated servers. | The performance of the public cloud is moderately lower as compared to the private cloud because of its shared servers. |
| The security offered by the private cloud is very high because of isolation. | The public cloud is less secure as compared to the private cloud because of its shared working principle. |
| Examples – Red Hat, VMWare, HP, Microsoft KVM. | Examples – AWS, GCP. |
We just saw the difference between the private cloud and the public cloud. In the coming-up section, we will look at the applications of the private cloud.
Applications of Private Cloud
We have seen what the private cloud is all about, also we have covered its advantages. Now it is time to check out where we can apply this concept in real-world scenarios.
By now, you should be able to say with some level of assurance if a private cloud is the best infrastructure option for your company. If performance, privacy, and control are your project’s top objectives, a private cloud is a wise choice.
The applications are based on the needs of clients who require a single-tenant system.
- Online Data Storage –
- File, images, audio file or any other type of data can be stored and accessed via Private Cloud.
- Locally storing large amounts of big data in this era of big data is not a good idea since it will take up more and more space. Storing it in a private cloud is a much better idea.
- Data storage and retrieval using private cloud storage is easy and efficient.
- Virtual Desktop Infrastructure –
- VDI in the cloud is a Desktop-as-a-Service (DaaS). A third-party vendor hosts the back end of a VDI deployment using a cloud service.
- Desktop operating systems can now be operated on virtual machines in the data centers of public cloud service providers thanks to DaaS.
- The backend of the applications –
- Cloud acts as a backend for web applications and websites.
- The private cloud maintains the resources, provides security measures, and contains the resources as well.
- Huge storage, virtual computers, virtual applications, traffic management systems, deployment methods, etc. are also included.
- Testing and Development –
- Private Cloud offers simple methods for testing and development for products.
- Setting up this environment through conventional means is not viable in terms of time consumption and efficiency in general.
- Private Cloud is also scalable, and having access to adaptable services makes it easier for planning, testing and overall development of Software solutions.
We have almost completed all the components which come under the basic introduction. Let’s move to the final section of the blog and discuss the disadvantages of private cloud.

Disadvantages of Private Cloud
Check out the below-mentioned pointers to conclude the final section of the blog.
- High Finances – As mentioned earlier we know that the private cloud has dedicated servers over the private network, and because of this the financial requirement is very high.
- Too Many Restrictions – Due to isolation and limited access, the working scope of the private cloud decreases. Only users within the organization are allowed to access the private cloud’s infrastructure.
- Limited Scalability – The private cloud has a very small scope of work. The systems used in the infrastructure are isolated, and due to this, it is not possible to scale the system.
- Skilled Manpower Required – Using the private cloud is not an easy task, because of too many restrictions there are more don’ts. To handle such a complex system skilled hands are required.
Types of Private Cloud
Now let’s have a look at the various different types of Private Cloud available for use since depending on the type, we will have different functionalities depending on our organization’s needs.
- Virtual Private Cloud – A Virtual Private Cloud can be considered as an isolated section in a Public Cloud enabling the organization to run the tasks isolated from the rest of the users in the public cloud.
- Hosted Private Cloud – A Hosted Private Cloud is provisioned specifically for the organization, even though the hardware, network and such are managed by the Service Provider, the server is occupied only by the organization.
- Managed Private Cloud – A Managed Private Cloud is a Hosted Private Cloud, the only additional aspect is that the cloud environment is managed by the Service provider making it perfect for organizations with not enough staff to manage the environments on their own.
Conclusion
In this blog post, we had an introduction to the private cloud, we learned about its working, applications, benefits to an organization it can bring, and at last the disadvantages of using the private cloud.
The private cloud is an isolated on-demand system that is used to provide you with the necessary resources you will be needing for your business. If you want a system that can run over single-tenant with privacy and security being your priorities then the private cloud is for you.
