The operational architecture artifact represents a network of computer systems that support some of the performance, scalability, and fault tolerance (among others) requirements of the solution.

操作体系结构构件表示计算机系统的网络，这些系统支持解决方案的某些性能、可伸缩性和容错等需求。

Selecting effective hardware, using fault tolerance, and price/performance analysis

选择有效的硬件，使用容错，以及性价比分析

Traditional software fault tolerance USES a great deal of branch instructions to detect errors, thus brings great overhead in both performance and power dissipation.

传统的软件容错技术频繁使用和比较分支指令检测错误，带来了巨大的性能和功耗的开销。

And rather than envision some sort of uber developer, who understands big data, web performance optimization, application middleware, and fault tolerance in a massively distributed environment, we need operations specialists on the development teams.
