Lesson Plan

• Describe the key characteristics of cloud computing.
• Compare the three main service models (IaaS, PaaS, SaaS) and identify typical use‑cases.
• Evaluate the advantages and disadvantages of different cloud deployment models.
• Apply a simple cost‑estimation formula to calculate monthly cloud expenses.
• Explain how the Internet enables cloud service delivery.

• Projector and screen
• Slide deck covering characteristics, service & deployment models
• Printed handouts of the service‑model table
• Cost‑estimation worksheet
• Laptops/computers with Internet access
• Demo account on a public cloud (e.g., AWS Free Tier)
• Whiteboard and markers

Begin with a quick poll: “Which apps on your phone rely on the cloud?” Connect this to prior lessons on networking protocols. Explain that today’s success criteria are to identify cloud models, weigh their pros/cons, and perform a basic cost calculation.

1. Do‑Now (5'): Students list three cloud services they use; share briefly.
2. Mini‑lecture (10'): Present key characteristics and the three service models with real‑world examples.
3. Interactive Table Activity (12'): In pairs, fill a blank table comparing IaaS, PaaS, SaaS (provider vs. consumer responsibilities).
4. Deployment Models Discussion (8'): Review public, private, hybrid, community clouds; list advantages/disadvantages on the board.
5. Cost‑Estimation Exercise (10'): Using the provided worksheet, calculate monthly cost for a hypothetical university virtual lab.
6. Concept Check (5'): Quick Kahoot quiz covering models and risks.
7. Wrap‑Up & Questions (5'): Summarise main points and address any misconceptions.

Recap the service and deployment models and how they relate to cost and risk. Ask each student to write one sentence describing the most suitable cloud model for a university virtual lab (exit ticket). For homework, students research a cloud provider’s pricing page and prepare a brief comparison with the lesson’s cost formula.
