单选题
Micro-service is a software development technology, which advocates dividing a single application into a group of small services，which coordinates and cooperates with each other to provide ultimate value for users.The micro-service ( ) has many important benefits.First, it solves the problem of business complexity.It decomposes the original huge single application into a group of services.Although the total amount of functions remains the same,the application has been decomposed into manageable services.The development speed of a single service is much faster,and it is easier to understand and（ ）.Second,this architecture allows each service to be（ ）independently by a team.Developers are free to choose any appropriate technology.Third,the micro-service architecture mode enables each service to be（ ）independently.Developers never need to coordinate the deployment of local changes to their services.These types of changes can be deployed immediately after testing.Finally,the micro-service architecture enables each service to（ ）independently.
A. architecture
B. software
C. application
D. technology
答案：A
解析
正确答案：A. architecture。
题干后文多次出现 "this architecture" 和 "micro-service architecture mode"，说明这里指的是“微服务架构”这一软件架构风格。微服务不是某个软件、应用或单一技术，而是一种把应用拆分为一组小服务的架构方式。
B. software：搭配不准确，微服务可涉及软件，但此处不是指某个软件。
C. application：微服务架构用于构建应用，但空处不是应用本身。
D. technology：微服务会用到多种技术，但本质是架构模式，不是一种具体技术。
考点延伸：微服务核心特征包括业务拆分、独立开发、独立部署、独立扩展、技术异构等。阅读填空题可利用后文复现词 "architecture" 定位答案。
