为了提高分布式系统的可靠性，复制技术被使用。我们提出了一个自适应的复制方案，使一个对象，以适应自己提供一个复制的服务，和一个复制的对象选择的复制策略，最适合实现其要求。应使用哪种复制策略取决于执行环境和应用程序。自适应复制方案允许更换的副本，或部分故障发生时，副本的数量的变化，并选择最适当的一致性协议为当前配置。最近适配的用于复制的对象的客户端应采取使其能够获得复制对象的全面服务的动作。可适应的复制方案正在被设计为Juice系统的一部分。Juice对象模型允许对象通过以模块化的方式替换某些组件来动态更改其行为。
To enhance reliability of distributed systems, replication techniques are used. We propose an adaptable replication scheme that enables an object to adapt itself to provide a replicated service, and a replicated object to choose the replication strategy that best fits to achieve its requirements. What kind of replication strategy should be used depends on an execution environment as well as an application. The adaptable replication scheme permits replacement of down replicas, or change of the number of replicas when partial failures occur and chooses the most adequate consistency protocol for the current configuration. Clients to the recently adapted objects for replication should take actions that enables then to obtain a thorough service of the replicated object. The adaptable replication scheme is being designed as part of the Juice system. The Juice object model allows objects to change its behavior on the fly by replacing some components in a modular way.
