So object cache must solve problems in system scalability, data integrity, data consistency and data fault tolerance etc.

对象缓存需要解决诸如系统的可伸缩性，数据完整性，数据一致性以及数据的容错性。

Fault tolerance can be provided by redundancy — redundant disks, computers, and even data centers — but it is transactions that make it practical to build fault-tolerant software applications.

可以通过冗余(冗余的磁盘、计算机以及数据中心)来提供容错，但是事务使得构建容错的软件应用程序成为可能。

Data systems for the military might have even more stringent fault-tolerance requirements.

军用的数据系统甚至可能有更严格的容错要求。

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.
