Cloud service models (IaaS, PaaS, SaaS) in Intro to Computing - Draw & Build Visually

Draw This - beginner

Draw a diagram that shows the three main cloud service models: IaaS, PaaS, and SaaS. Use simple boxes to represent each model and include a brief example inside each box. Connect the boxes with arrows to show how they build on each other, starting from IaaS at the bottom, then PaaS, and SaaS at the top.

Grading Criteria

Diagram includes three boxes labeled IaaS, PaaS, and SaaS

Boxes are stacked vertically with IaaS at the bottom, PaaS in the middle, SaaS at the top

Each box contains a correct example of the service model

Arrows connect the boxes showing the build-up from IaaS to SaaS

Labels and examples are clear and legible

This diagram shows the three main cloud service models stacked vertically.

IaaS (Infrastructure as a Service) is at the bottom. It provides basic computing resources like virtual servers and storage. Example: AWS EC2.

PaaS (Platform as a Service) is in the middle. It offers a platform with tools to develop and run applications without managing the underlying hardware. Example: Heroku.

SaaS (Software as a Service) is at the top. It delivers ready-to-use software applications over the internet. Example: Gmail.

The arrows show how each model builds on the one below it: SaaS uses platforms from PaaS, which in turn use infrastructure from IaaS.

Variations - 2 Challenges

[intermediate] Draw a flowchart that helps decide which cloud service model (IaaS, PaaS, or SaaS) a company should choose based on their needs: managing hardware, developing apps, or using ready software.

[advanced] Draw a detailed diagram showing the responsibilities of the user and the cloud provider in IaaS, PaaS, and SaaS models. Use two columns labeled 'User' and 'Provider' and list who manages what for each model.
