A clerk asks how using vendor SaaS for a citizen portal differs from building a custom portal on virtual machines. Which contrast is accurate?
Select an answer to reveal the explanation.
Short Explanation
Think ready-to-drive car versus buying an engine and chassis. SaaS is the finished app you just use; IaaS VMs are the raw machines you still have to build the portal on. Same citizen portal goal, totally different who-builds-what story.
Full Explanation
SaaS is the cloud service type where customers consume a finished application managed by the provider. Building a custom portal on virtual machines is an IaaS pattern: the city controls OS and app layers and must construct the solution. The two models are not interchangeable on who installs the guest OS or who delivers the finished portal.
