虚拟化基础设施可以进一步推进限制硬件类型的进展
。
你可以购买相同服务器
的机架
，
并根据应用需要将内存
、
CPU
和高性能远程存储分配给虚拟机
（

）。
说了这么多
，
越来越多的

。
因此主流的公有云提供商都
会提供基于
GPU

GPU
资源的大小
，
可以加速图形应用程序的性能
。
使用弹性
GPU
可能
会有收益
，
如果你需要少量的
GPU
用于图形加速
，
或者应用程序可以受益于只
需要一部分
GPU
同时也需要大量的计算

并发现
TPU
为机器
学习提供一个数量级更好的优化性能效率
。
随着新的应用程序领域的出现
，
硬件很可能是云或者服务器
，
将变得越来越异

。
这就要求在基础设施方面不断创新
。
自动化安装工具
在你开始考虑配置管理之前，必须确保服务器处于可配置状态。多年来，一些基
于相似技术的系统逐渐发展起来，它们可以自动（并且可重复）安装特定操作系
统的要求。
