Correct answer & explanation
✓
IaaS: Provides virtualized computing resources over the internet.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
IaaS: Provides virtualized computing resources over the internet.
Why this is correct
Infrastructure as a Service (IaaS) delivers on-demand virtualized computing resources such as VMs, storage, and networking.
- ✓
PaaS: Provides a platform allowing customers to develop, run, and manage applications.
Why this is correct
Platform as a Service (PaaS) offers a development and deployment environment in the cloud.
- ✓
SaaS: Provides software applications over the internet on a subscription basis.
Why this is correct
Software as a Service (SaaS) delivers fully managed applications accessed via a web browser.
- ✓
FaaS: Provides a platform to execute code in response to events without managing servers.
Why this is correct
Function as a Service (FaaS) allows running code in response to triggers, abstracting server management.
- ✗
IaaS: Provides a platform for developing and deploying applications.
Why it's wrong here
Incorrect — this definition describes PaaS, not IaaS. IaaS provides virtualized infrastructure, not a development platform.
- ✗
PaaS: Provides virtualized computing resources such as virtual machines.
Why it's wrong here
Incorrect — this definition describes IaaS, not PaaS. PaaS abstracts away infrastructure and focuses on application development.
