CompTIA A+ 220-1101 (V14) Practice Question

The correct answer is PaaS (Platform as a Service). PaaS provides a complete platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure. SaaS (Software as a Service) delivers ready-to-use software directly to the user over the internet on a subscription basis, with the provider managing the entire stack. IaaS (Infrastructure as a Service) provides only the virtualized computing resources (servers, storage, networking) over the internet; the user must still manage the operating systems and applications. A Community cloud is a deployment model, not a service model, where cloud infrastructure is shared by several organizations with common concerns.
