解説
問 22
Incorrectア
ASP (Application Service Provider) is a service in which the provider delivers business applications it has prepared to users over a network. It is not a form in which users bring in and install their own servers, so it does not meet the requirement of installing the company’s own backup server.
Incorrectイ
BPO (Business Process Outsourcing) means entrusting business processes themselves, such as accounting or human resources, in their entirety to an external specialist provider. It is not about renting space to install a server, and it is unrelated to the requirement of installing a server in a remote location for disaster recovery.
Incorrectウ
SaaS is a form in which users use software (applications) provided by a vendor as a service over the Internet. It does not provide a place to physically install the user’s own hardware (a backup server), so it is inappropriate.
- エ
正解 The correct answer is エ, colocation (housing). A colocation service is one in which the provider rents out installation space (racks), power, air conditioning, and communication lines in a robust data center, and the customer brings in its own servers or communication equipment to install and operate them there. The question asks to install the company’s own backup server, that is, to place a server the company itself owns in a different region. Entrusting your own backup server to a data center in a region far from your own computer center, in order to prepare for system failures caused by natural disasters, is exactly colocation, and it is appropriate as a remote backup site for disaster recovery.
ここがポイント
- Colocation (housing) is a service in which the user brings in its own equipment and installs and operates it in the provider’s data center facilities. The key point is that only the facility side is rented.
- ASP and SaaS are services that provide software or applications, and BPO is outsourcing of business processes; none of them provides a place to install the company’s own server. Do not confuse them with colocation.
