Public Cloud vs. Private Cloud: Choosing the Right Cloud Solution

Published on 03 Feb 2023

difference between the private and public clouds

The term "cloud storage" refers to a kind of computer service paradigm in which data is kept centrally yet may be accessed from anywhere and by any device at any time. The cloud is often separated into Private Cloud and Public Cloud, with the distinction depending on the user's requirements. As more and more businesses go to the cloud, they bring with them their own unique set of specifications and wants.

Private and public clouds each have advantages and disadvantages, and it's important to know each before deciding between them. Hence, in this blog, we’ll cover the difference between the private and public clouds.

What is a Public Cloud?

A cloud service provider owns and operates the hardware and software necessary for data storage and administration in the public cloud, making it available to users through the Internet.

When using public cloud services, customers may pool resources like servers, data storage, and even networks with other businesses that have signed up for the same service. Information stored in the cloud may be accessed in various ways, most frequently through a web browser or the cloud service's official app. A username and password will provide you access to sensitive corporate data.

Email, office software, and data storage may all be managed safely on the cloud. The public cloud services are Dropbox, Google Drive, Microsoft OneDrive, etc.

Benefits of the Public Cloud

Reduced expenses

Since public cloud models don't need hardware or software purchase, operation, or maintenance, they often have reduced IT expenses. In addition, most cloud computing plans include consumption-based pricing, so businesses pay only for the resources they utilize.

Minimal maintenance

The public cloud service provider handles all the upkeep of the cloud infrastructure and related assets.


By using the public cloud, businesses have access to an almost endless pool of computing resources, can simply adjust the size of their workloads to meet demand, and save costs.


In the case of a server loss or performance problem, public cloud workloads may be swiftly migrated to another server.

Disadvantages of the Public Cloud


The Shared Responsibility Model is used for public cloud architecture. Cloud infrastructure is monitored and protected, but client data, applications, workloads, and operating systems are not the service provider's responsibility. The burden for making such preparations rests solely on the buyer. Some users may need to be more familiar with the Shared Responsibility Model, while others may still need to implement effective cloud-centric cybersecurity policies. Companies using the public cloud risk being exposed to security flaws introduced by other tenants since the cloud is a shared resource.


The multi-tenant nature of the public cloud may require more work for certain businesses to satisfy regulatory compliance norms.

Vendor Dependency

While moving to the public cloud may result in substantial short-term cost reductions for most businesses, in the long run, that corporation will grow to depend on its selected cloud provider to keep its operations running smoothly. Therefore, the company risks being locked into a relationship with the vendor, although the charges may continue to rise.


Many businesses may need more time and effort to move to the public cloud. In addition, companies must exercise restraint when deciding what information, software, and services to put in the cloud since most public cloud platforms employ a pay-as-you-go pricing structure.

What is a Private Cloud?

Private clouds, also known as on-premises private data centers, are a kind of cloud computing in which the cloud, its services, and its corresponding infrastructure are used only by one company. A CSP often hosts private clouds, but one customer only uses them.

Many businesses choose private clouds because of the flexibility and privacy they provide. Organizations with sensitive data and stringent compliance requirements, such as government agencies, hospitals, and financial institutions, often utilize private clouds.

Benefits of the Private Cloud


Given that a private cloud is dedicated to a single customer and not shared with anybody else, that customer has full reign over the whole cloud infrastructure.


As long as the customer has implemented a thorough security policy tailored to the cloud, the private cloud offers far more control, privacy, and security than a public cloud where user data is shared.


Private cloud models allow businesses to tailor their cloud infrastructure to specific requirements, such as meeting industry or government regulations.


Private clouds provide better performance for most users since they do not have to share resources with other customers.

Disadvantages of the Private Cloud


The cost of employing a private cloud is nearly always higher than that of utilizing a public cloud. This is because the organization using the private cloud must either develop and operate its network or pay a third party to accomplish this on its behalf.

The burden caused by information technology

The vast majority of private cloud users need considerable information technology resources to set up, operate, and maintain the cloud environment.


Users of private clouds need to grow their workloads or transfer them across cloud environments as quickly as users of public clouds, making it difficult for enterprises to provide new services swiftly. On the other hand, as compared to the conventional on-premises architecture, the private cloud approach provides increased scalability.

Remote access

In most private cloud settings, mobile and distant access is severely restricted. Recent employment trends and the consequences of the COVID-19 epidemic have shown that most private cloud networks cannot handle the requirements of the contemporary workforce.

Public Cloud Vs. Private Cloud: Which Is Better?

When it comes to public cloud vs. private cloud, considerations, use cases, and constraints should be considered before deciding whether to employ a public or private cloud solution.

A private cloud implementation strategy is the best choice for firms with stringent performance, safety, and control requirements, while a public cloud is more cost-effective for smaller businesses. Hence, in conclusion, while both the public and private clouds have their own benefits and drawbacks, companies need to consider their objectives and goals while choosing one option.
