問 13
Incorrectア
“A business that provides communication lines for connecting to the internet, or that type of service” describes an ISP (Internet Service Provider). What an ISP provides is the connection itself (lines and means of access), which is different from what an ASP provides, namely application software.
Incorrectイ
“An internet service that forms a closed community which only registered member users can view” describes an SNS (social networking service). It is a service that provides a place for members to interact with one another, so both its purpose and what it provides differ from an ASP, which lends out business application software.
- ウ
正解 The correct answer is ウ. ASP stands for Application Service Provider. It refers to a business that runs application software on servers prepared by the provider and delivers it to multiple users over the internet (a network), or to that type of service. Its key feature is that users do not have to install and manage the software on their own PCs; they simply pay a usage fee for the period they need it. Choice ウ, “A business that provides application software running on a server to users via the internet, or that type of service”, is exactly this definition. Note that SaaS expresses the same idea as a category of cloud services, and ASP is positioned as a forerunner of SaaS.
Incorrectエ
“An approach that builds information systems from the perspective of the service the user uses, rather than from the perspective of products” describes service orientation (a design philosophy represented by SOA), which grasps and assembles a system in units of services. It is only a way of thinking about how to build systems, and it is not a term that refers to a concrete business or form of service provision the way ASP does.
ここがポイント
- ASP (Application Service Provider) = a business or form of service that lends out application software running on servers via the internet. Users do not buy, install, or maintain the software themselves; they pay a usage fee only for what they use.
- Telling confusing acronyms apart: ISP = provides internet access lines; SNS = a membership-based service for interaction; SOA / service orientation = an approach that builds systems from a service perspective. The term that expresses the same idea as ASP in terms of cloud service categories is SaaS.
