What are the two wide categories used to classify cloud computing?

The two wide categories are the deployment model and the service model.

What is the key difference in cost structure between Public Cloud and Private Cloud?

Public Cloud involves paying only for the resources used and the duration of use, whereas Private Cloud involves a huge upfront cost for exclusive ownership.

Who are the typical users for Infrastructure as a Service (IaaS)?

The users who generally utilize IaaS are IT administrators.

How does the responsibility model differ between PaaS and SaaS?

In PaaS, the user and vendor share responsibility (user uploads code/application), but in SaaS, the vendor manages everything, and the user only pays for the finished application.

Which major cloud providers were mentioned for IaaS?

Major cloud providers mentioned for IaaS are AWS, Azure, and Google.

Types Of Cloud Computing - Public, Private & Hybrid | Cloud Computing Services

Cloud Computing Deployment Models
📌 Cloud computing is categorized into deployment models: Public, Private, and Hybrid.
🚌 Public cloud is like taking a bus: accessible to anyone, paying only for the resources used and the duration of use (low cost).
🚗 Private cloud is analogous to owning a car: requires a large upfront payment and is exclusively owned and operated by a single organization.
🤝 Hybrid cloud offers the best of both, like renting a car—integrating existing infrastructure (like a Data Center) with cloud services.

Cloud Deployment Model Details
🌐 Public Cloud infrastructure is available over the internet and owned by providers such as AWS, Microsoft Azure, and IBM's Blue Cloud.
🔒 Private Cloud infrastructure is exclusively operated for a single organization, managed either internally or by a third party, and can be on-premises or off-premises (providers include AWS and VMware).
🏛️ Hybrid Cloud usage, often seen in federal agencies, involves using private clouds for sensitive data and public clouds for sharing non-sensitive information.

Cloud Computing Service Models (IaaS, PaaS, SaaS)
🛠️ Service models include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
💻 IaaS provides basic computing infrastructure on a pay-for-what-you-use model, suitable for IT admins who manage software installation (e.g., AWS, Azure, Google).
👨‍💻 PaaS offers a ready platform or runtime environment for developing and testing applications, allowing developers to deploy code without managing underlying infrastructure.
✅ SaaS delivers a finished, fully managed product accessed via the internet through a subscription model, requiring only a username and password for the end customer.

Service Model Comparison using Cake Analogy
🍰 On-Premises is like baking a cake entirely yourself, owning all ingredients, oven, and pan—maximum responsibility.
🥣 IaaS is like buying ingredients and mixing/baking the cake yourself using the provider's infrastructure (shared responsibility).
📱 PaaS is like ordering a cake by phone—you get the platform/environment to "run your code" (application), but you still need to arrange the table/garnish slightly (shared responsibility).
🍽️ SaaS is like dining out: buying a fully finished, garnished product with no effort or responsibility for making the cake.

Key Points & Insights
➡️ Deployment models categorize clouds by Public, Private, or Hybrid structure, mirroring real-world vehicle examples for cost and ownership.
➡️ Service models (IaaS, PaaS, SaaS) define the level of management and control retained by the user versus the vendor.
➡️ Users select the service model based on need: IaaS for infrastructure control, PaaS for development platforms, and SaaS for ready-to-use applications.
➡️ Resource management responsibility decreases progressively from On-Premises (highest management) down to SaaS (zero management).
