Taking a Cloud-Smart Approach to Harness the Power of Generative AI

We have all of these terms thrown around these with regards to “The Cloud”, so I thought it would be best that we get some close to accurate definitions of the private cloud, public cloud and hybrid cloud. Most of us there has their own way to provide these definitions, but I found the below definitions from Azure, which really has a good flow to define these types of clouds. We can definitely talk more around when and how to consume these, but as you will know it purely depends on the business needs. I will write a follow up blogs later on, around when and how to consume these clouds.

What is a private cloud?

“The private cloud is defined as computing services offered either over the Internet or a private internal network and only to select users instead of the general public. Also called an internal or corporate cloud, private cloud computing gives businesses many of the benefits of a public cloud – including self-service, scalability, and elasticity – with the additional control and customisation available from dedicated resources over a computing infrastructure hosted on-premises. In addition, private clouds deliver a higher level of security and privacy through both company firewalls and internal hosting to ensure operations and sensitive data are not accessible to third-party providers. One drawback is that the company’s IT department is held responsible for the cost and accountability of managing the private cloud. So private clouds require the same staffing, management, and maintenance expenses as traditional datacenter ownership.”

What is a public cloud?

“The public cloud is defined as computing services offered by third-party providers over the public Internet, making them available to anyone who wants to use or purchase them. They may be free or sold on-demand, allowing customers to pay only per usage for the CPU cycles, storage, or bandwidth they consume. Public clouds can also be deployed faster than on-premises infrastructures and with an almost infinitely scalable platform. Every employee of a company can use the same application from any office or branch using their device of choice as long as they can access the Internet.” 

What is a hybrid cloud?

A hybrid cloud is a computing environment that combines a public cloud and a private cloud by allowing data and applications to be shared between them. When computing and processing demand fluctuates, hybrid cloud computing gives businesses the ability to seamlessly scale their on-premises infrastructure up to the public cloud to handle any overflow—without giving third-party datacenters access to the entirety of their data. Organisations gain the flexibility and computing power of the public cloud for basic and non-sensitive computing tasks, while keeping business-critical applications and data on-premises, safely behind a company firewall.

Using a hybrid cloud not only allows companies to scale computing resources, it also eliminates the need to make massive capital expenditures to handle short-term spikes in demand as well as when the business needs to free up local resources for more sensitive data or applications. Companies will pay only for resources they temporarily use instead of having to purchase, program, and maintain additional resources and equipment that could remain idle over long periods of time. Hybrid cloud computing is a “best of all possible worlds” platform, delivering all the benefits of cloud computing—flexibility, scalability, and cost efficiencies—with the lowest possible risk of data exposure.
