The creation of a distributed system is a major engineering exercise, often costing many millions of dollars to design, and several times more to operate. Indeed, the total cost in North America just to keep existing computing systems functioning exceeds $40 billion annually. In spite of this expense, computer systems are typically insecure and unreliable. The single major cause of this problem is that the complexity of these systems exceeds the abilities of all but the very best of human experts. Even the installation of a networked home computer often requires significant systems knowledge. The evidence suggests that this complexity is inherent. Over time this problem will get worse not better, as we build larger systems and inter-connect those systems.

分布式系统的创建是一项重大的工程实践，通常需要花费数百万美元进行设计，而操作成本则要高出数倍。 事实上，在北美，仅维持现有计算系统运行的总成本每年就超过400亿美元。 尽管如此，计算机系统通常是不安全和不可靠的。 这个问题的唯一主要原因是，这些系统的复杂性超过了所有人的能力，但最好的人类专家。 即使是安装联网的家庭计算机也往往需要大量的系统知识。 证据表明，这种复杂性是固有的。 随着时间的推移，这个问题会变得更糟，而不是更好，因为我们建立了更大的系统，并将这些系统相互连接。
