概述
|
21
数减少也可以提高每个系统的效率:由于每台机器上的资源(
CPU
、
RAM
等)
使用率提高了,因此每个容器的总成本就会相应降低。
随着技术栈中开发实例成本的降低,我们可以实现以往因成本过高而受阻的
开发实践。例如,通过
Kubernetes
部署应用程序,则每次技术栈中的开发人
员贡献提交时,我们都可以执行部署和测试。
如果每个部署的成本可以通过少量容器(而不是多个完整的虚拟机)来衡量,
则你为这种测试而付出的成本就会大大降低。回到
Kubernetes
本身价值的话
题,这类测试的增加可以提高开发速度,因为你非常有信心,不仅代码的可
靠性大大提高,而且系统还提供了详细信息,可以帮助你快速找出何处引发
了问题。

小结
Kubernetes
的建立初衷是为了彻底改变在云中构建和部署应用程序的方式。
Kubernetes
的根本目标是提高开发人员的速度、效率以及敏捷性。在本章中,
我们介绍了为什么应该使用
Kubernetes
部署应用程序。在接下来的几章中,
我们将介绍如何部署应用程序。
