Amazon Web Services is which type of cloud computing distribution model?

  1. Software as a Service (SAAS)

  2. Platform as a Service (PAAS)

  3. Infrastructure as a Service (IAAS)

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

AWS EC2, S3, RDS, and VPC provide foundational computing infrastructure - virtual machines, storage, networks - that you configure and manage. This is the definition of IaaS. SaaS (A) would be something like Gmail or Office 365 - ready-to-use applications. PaaS (B) would be Heroku or Google App Engine where you deploy code without managing servers. AWS offers some PaaS services (like Elastic Beanstalk) but AWS as a whole is IaaS.
