Public vs Private Cloud Understanding the Difference

15.12.2023

Cloud computing has revolutionized the way businesses operate by providing a range of benefits, including scalability, flexibility, cost-effectiveness, and more. However, there are different types of cloud services available, with two main options being public and private cloud. In this article, we will explain what public and private cloud mean, how they differ, and which one is best suited for your business needs.

What is Public Cloud?

Public cloud refers to a type of cloud computing where all resources, such as hardware, software, and infrastructure, are owned and managed by third-party service providers. These providers offer their services through the internet to the general public, and users can access them on-demand or pay-as-you-go basis. Some examples of public cloud platforms include Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and IBM Cloud.

What is Private Cloud?

In contrast, private cloud refers to a type of cloud computing where all resources are owned and managed by a single organization, either on-premises or through a third-party vendor. Private clouds are designed to provide the same benefits as public clouds, such as scalability, flexibility, and cost-effectiveness, but in a more secure and dedicated environment. Private clouds are often used by businesses that require high levels of security, regulatory compliance, and customization.

These 5 particular use instances will finally be expanded by IBM and also will be made out there to the ecosystem for enlargement by particular person corporations and/or distributors. And though these Cloud Paks are optimized to run on the IBM Cloud, as a result of they're constructed on prime of OpenShift they can run on just about any cloud basis, making a no-lock-in answer that must be extra palatable to corporations who aren't IBM-centric or unique.

Case Studies for Public and Private Cloud

Public Cloud Case Study: Netflix

Netflix is a popular streaming service that uses public cloud infrastructure to deliver content to its millions of subscribers worldwide. By using AWS, Netflix is able to scale its operations quickly and efficiently, handle large volumes of traffic, and reduce costs by only paying for the resources it needs at any given time.

"There are a number of major benefits that we're trying to benefit from in community virtualization," says Kevin Younger, principal engineer for Ceridian's Dayforce. Initially is safety and microsegmentation."

Ceridian is utilizing VMware's NSX-T to allow microsegmentation, which provides extra granular safety controls for better assault resistance. It is a rigorous method, and it requires time-consuming evaluation and planning to get it proper. "We begin with a zero belief method within the very starting," Younger explains. "This forces us to know our utility nicely, and in addition forces us to correctly doc and open solely the holes required for the applying, safety being firstly."

Security and Privacy

Public clouds are generally less secure than private clouds because they are accessible to the general public. While public cloud providers offer various security measures, such as firewalls, encryption, and access controls, these measures may not be sufficient for businesses that require high levels of security and privacy. Private clouds, on the other hand, provide a more secure and dedicated environment that can be customized to meet specific security requirements.

Cost

Public clouds are generally more cost-effective than private clouds because they operate on economies of scale. Public cloud providers can spread their costs across many customers, which reduces the per-customer cost. In contrast, private clouds require significant upfront investments in hardware, software, and infrastructure, and ongoing maintenance and support costs.

Customization

Private clouds provide more customization options than public clouds because they are designed to meet the unique needs and requirements of a single organization. Businesses that require specialized applications, workflows, or configurations may prefer private clouds over public clouds, which offer limited customization options.
