解説
問 42
- ア
正解 The correct answer is “ア DevOps.” DevOps is a term combining Development and Operations. It refers to an initiative and culture in which the two sides work closely together without building walls, actively adopt mechanisms (such as CI/CD) that automate building, testing, and production deployment (deploy), and quickly and continuously release new features to keep improving the service. The statements in the question — “the development side and the operations side cooperate,” “automate operations and production deployment,” and “release new features to improve the service” — all match the characteristics of DevOps, so this is the most appropriate.
Incorrectイ
RAD (Rapid Application Development) is a method that develops a system in a short period by repeatedly creating prototypes and having users evaluate them. It is a method about development speed, not a term that describes cooperation between the development and operations sides or the automation of operations and production deployment.
Incorrectウ
Object-oriented development is a development technique that designs and implements a system in units of “objects,” which bundle data and processing together. It is an idea about structuring and reusability of software, not a term that describes cooperation with the operations side or automation and continuous release.
Incorrectエ
Test-Driven Development (TDD) is a development method in which test code is written before the implementation, and the program is implemented so that it passes those tests. It is a coding method for ensuring quality, not a term that describes cooperation between the development and operations sides or the overall initiative of improving the service.
ここがポイント
- DevOps is an initiative and culture where development (Dev) and operations (Ops) cooperate and continuously release new features through automation (CI/CD) to improve the service.
- Distinguish from similar development-method terms: RAD = short-period development, object-oriented = design technique, TDD = test-first coding method.
