ITPEC FE Morning October 2019 Question 65

Using the functions of application software via the Internet only when necessary — that is SaaS.

SaaS (Software as a Service) is a cloud service model: the application runs on the provider's system, the user connects through the Internet, usually with a web browser, and pays for the functions and period used instead of buying, installing and maintaining the software.

Answer (a)

Why not others:

• •(b) — a software package for integrated management of core business operations and company resources is ERP
• •(c) — a document agreeing the service quality between the customer and the service provider is an SLA (service level agreement)
• •(d) — a far-reaching redesign of the organization, business flow and information systems is BPR (business process reengineering)

Key rule: SaaS provides the application, PaaS the platform to build and run your own, and IaaS the bare infrastructure (servers, storage, network).
