Public Cloud vs Private Cloud Solutions: Differences & Similarities

Updated 8 Sep 2022

At first look, the world of cloud computing may appear overwhelming due to its heavy use of jargon and acronyms. While we are discussing two today, there are actually 2 types of cloud computing. You’re not the only one who may be unsure of the distinction between public and private clouds. You’re also in the perfect place to learn more about them!

Today, we’ll explain some of the vital differences between public vs private clouds in this article in a straightforward manner. We’ll go over the definitions of the public and private clouds as well as the fundamentals of cloud architecture that you should be familiar with.

 

What is a public cloud?

It’s usually reasonable to assume that when individuals discuss cloud computing and cloud migration, they’re asking what is public cloud and what benefits given public cloud

Anybody who wishes to rent services can do so through the public internet using a public cloud.

A third-party provider manages services and resources (such as servers or storage) via the open internet. These services come in both free and pay-per-use varieties.

Public cloud brands and cloud service companies include Alibaba Cloud, IBM Cloud, Oracle Cloud, Google Cloud Platform, Microsoft Azure, and Amazon Web Services (AWS), which host these services. As of late public cloud adoption in financial services has been growing rapidly.

Because they are accessible to everyone, these clouds are known as “public” clouds. Their services can be accessed by everyone with an internet connection and a payment card.

To supplement their existing businesses, some sizable traditional IT corporations, including IBM, SAP, and Oracle, have developed public cloud companies. A good illustration of this is Microsoft Azure.

 

What is a private cloud?

In a private cloud, only users from one company or group can access the computing resources. Private clouds can be set up by businesses in their own data centres or with a hosting company.

Cloud resources are owned and used by one business only in a private cloud. Because of this, this strategy is frequently favoured by political and financial sectors that aim for maximal control or customisation.

On-premises installations are another name for private cloud deployments. The private cloud deployment paradigm frequently resembles the conventional IT technique very closely, but it makes greater use of resources through application management and virtualization.

 

Similarities between private and public cloud

In order to understand how the limitations of each cloud computing architecture and its services could affect your organization, let’s examine the similarities between the private vs public cloud.

  1. Placement or workload

Many decision aspects common to both public and private are considered for better workload placement. Business, technical, and ecosystem considerations are among them. Company considerations can include things like service level agreements, worldwide reach, regulatory or compliance issues, and business asset control. Security, performance, workload elasticity, backend integration, and ability to manage particular data quantities are just a few of the technical factors that both models must take into account. 

  1. Scalable computing resources

In their separate networks, public and private clouds both abstract and share scalable computing resources. Hardware, software, networks, servers, storage applications, and services are all examples of configurable computing resources. Both computing models demand little work from consumers or service providers to provide, use, and release the shared pool of resources.

  1. Mix of technologies

Public and private clouds make up a distinctive fusion of technology. This comprises the operating system, some sort of administration platform, and APIs. Regardless of the underlying hosting architecture, i.e., public or private, APIs enable seamless interaction between applications, external software components, and operating systems or microservices.

 

The difference between private cloud vs public cloud?

As the similarities are many, the differences between the two are quite straightforward. To describe it simply, A private cloud is a service that is solely managed by one company and is not accessible to the public. A public cloud, on the other hand, is a subscription service that is made available to any and all clients who require comparable services.

Here is an analogy to help cement their difference:

  • A private cloud is comparable to a company operating and maintaining its own fleet of trucks. You assume all responsibility and total control over the data and security (cost, maintenance).
  • A public cloud is comparable to renting vehicles from a large firm that the entire world also uses. SLAs (service-level agreements) allow you to set up cost-security trade-offs, and resources can be reused or shared.

Conclusion

In order to advance cloud technologies, both private and public clouds have been essential. Public clouds echo accessibility, simplicity of setup, and cost, whereas private clouds stress privacy, isolation, control, and customization. Large enterprises should therefore select a private cloud model if they want to own a cloud setup and have superior control, security, privacy, and customizable settings as needed.

Business-critical systems have been moving to private clouds at a rapid rate at several well-known firms. Small businesses can use the public cloud if they don’t care about exclusive ownership and are comfortable with the pay-as-you-go pricing structure. 

Additionally, businesses need to keep in mind that the ideal cloud infrastructure may very well not be a public cloud private cloud hybrid cloud only option, it may be a hybrid of private and public models.
