What Is a Public Cloud?

Today, businesses around the world rely on the cloud to store and share their digital information. There are multiple types of clouds that are available for IT departments, and one type is the public cloud. This post will provide a thorough explanation of the public cloud, its workings, and its comparison with other types of clouds.

What is a public cloud?

A public cloud constitutes computing services offered by third-party providers over the public Internet. They are either free or sold on-demand, and customers pay per usage for their CPU cycles, bandwidth, or cloud storage.

How does a public cloud work?

Operating on the standard cloud computing model, a public cloud provides resources, like virtual machines (VMs), applications or storage, available to the general public over the internet. The hardware and software necessary for supporting the cloud services are owned and managed by the cloud provider. In the public cloud, multiple customers share the same infrastructure pool with limited configurations, security protections, and availability variances.

Why choose a public cloud?

Choosing a public cloud comes with several advantages. It offers scalability and flexibility; users can scale up or down based on their needs. There is also no need for businesses to invest heavily in their own on-site IT resources. Moreover, the pay-as-you-go model can be a cost-effective solution for businesses, as they only pay for the services and resources they use.

Public cloud vs. private cloud vs. hybrid cloud

When it comes to choosing between a public, private, or hybrid cloud, different factors come into play. A private cloud is dedicated to a single organization providing more control over data, infrastructure, and security. However, it requires significant investment and expertise to set up and manage.

On the other hand, a hybrid cloud merges the public and private clouds. It allows data and applications to move between the two environments. It provides more flexibility and more deployment options. It also allows for better control over privacy, compliance, and security.

Which cloud is best for your organization?

Offering flexibility, scalability, and cost-effectiveness, public cloud services present themselves as a powerful tool for businesses aiming to bolster their IT capabilities. Yet, the choice between public, private, or hybrid cloud services remains contingent on the specific needs and requirements of each organization. By understanding these distinctions, one can make informed decisions about which cloud service best suits their operational needs. The future of IT is here, and it is floating on a cloud.
