Curriculum Overview: Cloud Deployment Models (Public, Private, & Hybrid)
Define cloud models, including public, private, and hybrid
Curriculum Overview: Cloud Deployment Models
This curriculum provides a structured pathway to mastering the fundamental cloud deployment models as defined in the Microsoft Azure Fundamentals (AZ-900) exam. It explores the technical and business considerations of Public, Private, and Hybrid cloud environments.
Prerequisites
Before beginning this module, learners should have a foundational understanding of the following:
- General IT Concepts: Basic understanding of servers, storage, and networking.
- Internet Connectivity: Awareness of how public and private networks function.
- Basic Cloud Awareness: Understanding the concept of "Cloud Computing" (on-demand delivery of compute power/database/storage via the internet).
Module Breakdown
| Module | Topic | Focus Area | Difficulty |
|---|---|---|---|
| 1 | Introduction to Cloud Models | High-level definitions and commonalities. | ⭐ (Beginner) |
| 2 | The Public Cloud | Shared infrastructure and multi-tenancy. | ⭐ (Beginner) |
| 3 | The Private Cloud | Single-tenant environments and dedicated hardware. | ⭐⭐ (Intermediate) |
| 4 | The Hybrid Cloud | Integration, data sovereignty, and legacy systems. | ⭐⭐⭐ (Advanced) |
| 5 | Comparative Analysis | Use cases, cost, and responsibility mapping. | ⭐⭐ (Intermediate) |
Module Objectives
Module 1: Introduction to Cloud Models
- Identify the three primary deployment models: Public, Private, and Hybrid.
- Understand that the fundamental difference lies in privacy of infrastructure and data, not necessarily physical ownership.
Module 2: The Public Cloud
- Define Multi-tenancy and shared resource pools.
- Describe why Public clouds (Azure, AWS, GCP) utilize the public internet for access.
- Explain the Consumption-based model (Pay-as-you-go).
Module 3: The Private Cloud
- Define Single-tenant environments.
- Distinguish between On-Premises Private Cloud (owned hardware) and Hosted Private Cloud (third-party hardware, dedicated to one organization).
- Analyze why privacy and regulatory concerns drive private cloud adoption.
Module 4: The Hybrid Cloud
- Identify the Hybrid model as a mixture of Public and Private clouds.
- Describe technical scenarios like accessing on-premises data from a public cloud application.
- Explain the role of Hybrid cloud in migrating Legacy Systems.
Module 5: Comparative Analysis
- Compare and contrast the levels of control vs. management overhead across models.
- Select the appropriate model based on a given business scenario (e.g., highly regulated data vs. high-scale web app).

Success Metrics
To demonstrate mastery of this curriculum, the learner must be able to:
- Define Tenancy: Correctly identify why a Private cloud is called a "single-tenant" environment.
- Identify Hybrid Logic: Explain why a company might keep a database on-premises while running a web front-end in the Public cloud.
- Ownership Myth-Busting: Articulate that a Private cloud does not require the organization to own the hardware (it can be hosted by a third party).
- Scenario Matching: Given a list of constraints (e.g., "Must comply with strict government data residency laws"), select the most appropriate cloud model.
Real-World Application
[!IMPORTANT] Choosing a cloud model is rarely just a technical decision; it is a business strategy.
- Regulatory Compliance: Banks and healthcare providers often use Private clouds for sensitive PII (Personally Identifiable Information) while using Public clouds for their public-facing websites.
- Cloud Bursting: An e-commerce company uses a Hybrid model to run normal operations on a Private cloud but "bursts" into the Public cloud during Black Friday to handle high traffic spikes.
- Legacy Modernization: Companies with older mainframe systems use Hybrid cloud as a bridge, allowing them to modernize parts of their application stack without a massive "rip-and-replace" of their existing data center investments.
