Types of Cloud Computing (Public, Private, and Hybrid)
In Part 1, we looked at what cloud computing is and why it matters. Now that we understand the basics, the next step is learning about the different types of cloud computing. These types are also known as cloud deployment models.
This post breaks them down in a very simple way, so even if you’re brand new to cloud computing, you can follow along with confidence.
What Are Cloud Deployment Models?
Cloud deployment models describe where the cloud services are hosted and who can access them. There are three main types:
•Public Cloud
•Private Cloud
•Hybrid Cloud
Each one is used for different reasons depending on business needs, security requirements, and cost.
Public Cloud
The public cloud is the most common type of cloud computing.
In a public cloud:
•Cloud services are owned and managed by a cloud provider
•Resources are shared between many users
•Services are accessed over the internet
Examples of public cloud providers include Microsoft Azure, Amazon Web Services (AWS), and Google Cloud.
Simple Example:
Using OneDrive, Gmail, or Microsoft Teams is an example of public cloud usage.
Why People Use Public Cloud:
•Low cost (pay only for what you use)
•No need to manage hardware
•Easy to scale up or down
•Quick to set up
Public cloud is ideal for beginners, small businesses, and organizations that want flexibility.
Private Cloud
A private cloud is used by one organization only.
In a private cloud:
•Resources are not shared with other organizations
•It can be hosted on-site or by a cloud provider
•The organization has more control over security and data
Simple Example:
A company running its own cloud environment for sensitive data like financial or medical records.
Why People Use Private Cloud:
•Higher level of control
•Better for sensitive or regulated data
•Custom security settings
Private cloud is often used by large organisations or industries with strict compliance requirements.
Hybrid Cloud
A hybrid cloud is a mix of public cloud and private cloud.
In a hybrid cloud:
•Some resources are kept in a private cloud
•Other resources run in the public cloud
•Both environments work together
Simple Example:
A company keeps customer data on a private cloud but uses public cloud services for websites or applications.
Why People Use Hybrid Cloud:
•Flexibility
•Better control over sensitive data
•Ability to move workloads between environments
•Gradual move to the cloud
Many organisations use hybrid cloud because it combines the benefits of both public and private clouds.
Which Cloud Type Is Best?
There is no single “best” cloud type. The right choice depends on:
•Budget
•Security needs
•Type of data
•Business goals
For beginners and learners, the public cloud is the easiest place to start, especially when learning platforms like Microsoft Azure.
Why This Matters for Cloud Learning
Understanding cloud types helps you:
•Understand real-world cloud environments
•Make better design decisions
•Prepare for cloud certifications
•Build strong foundational knowledge
These concepts are especially important in beginner certifications like AZ-900 and SC-900.
Public, private, and hybrid clouds each serve different purposes. Learning the differences between them helps you understand how organizations choose and use cloud technology in the real world. This knowledge is an important step in any cloud learning journey.
