Private Cloud vs Public Cloud – Know the difference

Public cloud vs private cloud


What is Cloud computing?

Cloud computing is a platform that allows the efficient delivery of computing services on the internet. These include storage, databases, software, and servers. Not only does this ensure affordable costs, but it also allows smooth operations.


This highly reliable network and secure service comprise many different types. These vary in terms of models and services offered. Thus, users choose the one that is right for them and fulfills their demands and expectations.


The first step is to decide the deployment type that will be your services’ foundation. There are three options: private, public, and hybrid cloud. Each option carries a list of benefits and risk factors to be assessed before choosing the right cloud.


Scroll down to see each cloud’s pros and cons, and you’ll know which one suits your company and its expectations! But, no matter your choice, you will be exhilarated as a business!


What is Public Cloud?

Public clouds are systems that work on the standard computing model. A third party, the cloud service providers, is in charge of the clouds and carries on the operations. The cloud provider manages and owns all the hardware, infrastructure, and software. 


Resources such as storage, applications, and machines are available for the client to access on a web browser through a network connection. These services may be using public internet or a dedicated network. The services may be cost-free or offered with a range of subscriptions. The expenses, however, are limited.


Dramatic growth in this sector has been seen in recent years. A 17.5% market profit was seen in 2019, which increased to $214.3 billion from $182.4 billion within a year. These stats speak for themselves. With effective use being billed and low financial requirements, startups and small companies find this model incredible.


This type of cloud is preferable for many companies as it saves time. The cloud providers carry out testing and utilizing products, and the enterprises have little responsibility in setting up. The low expenses and high cost savings for other purposes further hyped-up these benefits.


However, this system brings several drawbacks it. Control and security are questions left unanswered. While we know that the data remains isolated, the authority is in the hands of the third party and may compromise security. Misuse and mismanagement by other companies can put yours at risk.


Furthermore, as several different companies share the cloud and the resources are divided considering the room for change, there are high levels of scalability. With varying peak demands for storage and services, you can increase your business at any rate without additional financial or non-financial incentives. While this is an excellent reason to choose a public cloud, the lack of support might be a disadvantage. 


Some third parties do not provide services per the requirement, and the companies are expected to find solutions to their problems and tackle issues themselves.


What is a Private Cloud?

Private clouds are single-tenant environments made and used for an individual company. As the company does not share resources with other companies, they have the power to decide what supplies to keep and how to use them.Virtualization software is a significant aspect of the private cloud too.


The proprietary nature of the private cloud makes it exemplary for huge businesses which solely depend on governance policies and requirements. Private cloud users get nearly the same advantages as public cloud users and the opportunity to use virtual machines with authority to make alterations. Thus, they get to reap all the cloud-computing benefits and ownership. This opportunity is the most significant flex the private cloud companies have to make!


On the other hand, private clouds do have some difficulties to encounter. The private clouds cater to an individual enterprise, so the company is entirely in charge of the expenses. Deployment, maintenance, and support cost a ton, sometimes keeping other finances at stake. While financials are just one side of the story, increased demand leads to more staff and IT requirements.


As the party vendor does not present any support, unlike the public cloud, the private companies have to arrange a proficient IT staff at all times. Moreover, a private network is required for the system to work, adding to more responsibility and costs.


Although the private clouds guarantee the security of sensitive data and high-end reliability, the companies are catering to several clients simultaneously, which may hinder the server’s maintenance and lead to overburdening. Unfortunately, such a cloud environment would lead to the same issues encountered by public cloud users. However, this is seen very rarely.


There are three different types of private clouds



This private cloud is instilled in a public cloud that gives the users two-in-one support. While sharing the server and bound to the privileges of the public cloud, they enjoy the isolation and individuality they are offered. Companies that prefer a hybrid model mostly use this.



The companies do not share servers in a hosted private cloud. Although the third party is in charge of the hardware maintenance and the software updates and usage, an individual company solely uses the server.



This private cloud is a hosted cloud with additional benefits. The provider is in charge of all the management and deploys many more services like storage. This cloud is a good option for companies without the staff and resources to manage a private cloud alone.

The private cloud infrastructure is also variable. For example, some companies prefer software only while others require software and hardware, depending on their customized requirements.


Similarities between Public Cloud and Private cloud

In both public and private clouds, considerations are made before final decisions. These include acknowledgment of the ecosystem, business requirements, and technical resources that are available and needed. Business consideration is vital and consists of the regulatory aspects, assets, global reach, and agreements. 


Moreover, both types of clouds require many technologies. These include the operating system, platform, and APIs. These are necessary for the connection of different methods and communication. Finally, highly efficient technology is required to allow backup, smooth control, and a systematic approach.


Private cloud vs Public cloud  

The same cloud computing infrastructures support multiple customers. Cloud computing infrastructure supports a single private organisation.
The data of multiple private organisations is stored on a shared platform. However, it is hidden and shared only if permission is granted per the rules. Data of each enterprise is isolated.
All the possible services are provided. As different organizations have different demands, the services and hardware contain a range of diverse options. Although the companies have individual users, they use a mutual resource pool. Only specific hardware and services per the company’s requirement are accessible. The enterprise can choose to make customizations and alterations as per their need.
The service provider is in charge. The service provider or the enterprise is in charge.
It works well with the public internet. Only a private internet network can support the system. 
Can make a versatile range of changes. The system allows limited changes.
Moderately reliable Highly reliable
Managed by the cloud service provider (third party) The private company has the authority. It works and uses the cloud.
Low costs as compared to private cloud It is expensive as compared to the public cloud 
  Security is governed by the third party and may be unreliable at times Efficient security is ensured.
Moderate performance is seen. High performance is seen.
  Several companies share servers. Servers are dedicated and individual.
These are good for small-sized companies and those that work to regain the cloud after calamities. This is suitable for companies that require high-end safety and protection of critical data and applications.
Quick deployment takes place. As the hardware is entirely under the cloud providers, little effort and no long contracts are required. Deployment is a long process, and help from IT professionals and proficient staff for managing software and hardware is required.
Example: Amazon Web Service, Google AppEngine Example: Microsoft KVM, HP, Red Hat & VMWare

When deciding what the best cloud option for your company is, you must look at both pros and cons. Some factors to consider are:


  • The cost of operating each model
  • The demand and workload of your network
  • The need for customization
  •  How secure should your data be
  •  The updated requirement of your system
