ITPEC FE Morning April 2019 Question 64
Which of the following is a scheme where the user establishes a connection to the system of a service provider via the Internet and makes online use of only the necessary functions of the applications provided by the service provider at the necessary time?
Explanation
SaaS — the user reaches the provider's application over the Internet and uses only the functions needed, when they are needed.
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 and installing the software.
Answer (b)
Why not others:
- •(a) ERP — Enterprise Resource Planning, integrated management of company-wide resources such as production, sales and accounting; a kind of business system, not a way of delivering software
- •(c) SCM — Supply Chain Management, sharing information across companies from procurement to sales
- •(d) XBRL — eXtensible Business Reporting Language, an XML-based format for financial reports
Key rule: SaaS provides the application, PaaS the platform to build and run your own, and IaaS the bare infrastructure (servers, storage, network).
