解説
問 30
Incorrectア
Outsourcing refers to the form in which tasks such as operating and maintaining an information system are entrusted to an external specialist provider. It is not the form of operating the system oneself within the company’s own facilities; it hands the work over to an outside party, which is the opposite of the question, so it is wrong.
- イ
正解 On-premises refers to the form in which information systems such as servers and software are installed by the company itself within premises managed by the company (a data center or in-house facilities) and are operated and managed by the company. The statement in the question, “deploy and operate within facilities that the company manages,” matches this definition exactly, so the correct answer is イ. Its characteristic is that it does not rely on external providers or services delivered over a network, keeping the equipment and data under the company’s own control.
Incorrectウ
Cloud computing refers to the form in which computing resources or services provided by an external provider are used over a network such as the Internet. The system itself resides not within the company’s own facilities but on the provider’s side, which contradicts the question’s “within facilities managed by the company,” so it is wrong.
Incorrectエ
Grid computing refers to a technology that links many computers over a network and coordinates them, treating them as a single high-performance virtual computer to perform processing. It is not a term that describes the form of the deployment/operation location, and does not match the intent of the question, so it is wrong.
ここがポイント
- On-premises = the form in which an information system is installed in on-site facilities managed by the company and is operated and managed by the company itself (in contrast, the cloud uses services delivered by an external provider over a network).
- Distinguish between terms that describe the usage/operation form of a system (on-premises / cloud / outsourcing) and terms that describe the processing method (grid computing) when memorizing them.
