AWS EC2 is an example of which cloud service model?

  1. SaaS (Software as a Service)
  2. PaaS (Platform as a Service)
  3. IaaS (Infrastructure as a Service)
  4. FaaS (Function as a Service)
Show answer and solution

Correct answer: C. IaaS (Infrastructure as a Service)

EC2 (Elastic Compute Cloud) provides virtual machines where YOU manage the OS, runtime, and apps. This is the classic Infrastructure-as-a-Service (IaaS) model.

A HYBRID cloud deployment model combines:

  1. Two different public cloud providers
  2. Multiple regions of the same public cloud
  3. Two different VPCs within one cloud
  4. Both public and private cloud environments
Show answer and solution

Correct answer: D. Both public and private cloud environments

HYBRID = mix of PUBLIC + PRIVATE cloud, with workloads spanning both. Often used to keep sensitive data on-premise while bursting compute to public cloud.
