Infrastructure as a Service (IaaS)

Software as a Service (SaaS)
D.
On-premises datacenter
How to approach this question
Identify the service model designed specifically for developers to host code without managing servers.
Full Answer
B.Platform as a Service (PaaS)✓ Correct
Platform as a Service (PaaS)
Platform as a Service (PaaS) is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating. It allows developers to avoid the expense and complexity of buying and managing software licenses, underlying application infrastructure, and middleware.
Common mistakes
Choosing IaaS because web apps run on servers. While true, PaaS is the *most appropriate* choice when the requirement is to avoid managing those servers.
