摘要:
我们提出了容器数据项(CDI),这是一种抽象数据类型,允许多个容器在保持其强大的安全性和隔离语义的同时,高效地对一个共同的数据项进行操作。应用开发者可以使用 CDI 使多个容器对同一数据进行操作、在彼此之间同步执行,并在运行时控制共享数据项的所有权。这些容器可以位于同一服务器或不同服务器上。CDI 旨在支持基于微服务的应用,这类应用由一组相互连接的微服务组成,每个微服务由单独的专用容器实现。CDI 通过确保在任意时刻恰好有一个容器拥有 CDI 对象,并且 CDI 对象的所有权只能由当前 CDI 对象所有者转移给另一个容器,来保持容器的重要隔离语义。我们提出了 CDI 的三种不同实现,使位于同一服务器上的不同容器以及位于不同服务器上的容器能够使用 CDI 高效地对共同的数据项进行操作。本文提供了对 CDI 的广泛性能评估,以及两个代表性应用:一个增强现实应用和一个去中心化工作流编排器。
英文摘要:
We present Container Data Item (CDI), an abstract datatype that allows multiple containers to efficiently operate on a common data item while preserving their strong security and isolation semantics. Application developers can use CDIs to enable multiple containers to operate on the same data, synchronize execution among themselves, and control the ownership of the shared data item during runtime. These containers may reside on the same server or different servers. CDI is designed to support microservice based applications comprised of a set of interconnected microservices, each implemented by a separate dedicated container. CDI preserves the important isolation semantics of containers by ensuring that exactly one container owns a CDI object at any instant and the ownership of a CDI object may be transferred from one container to another only by the current CDI object owner. We present three different implementations of CDI that allow different containers residing on the same server as well containers residing on different servers to use CDI for efficiently operating on a common data item. The paper provides an extensive performance evaluation of CDI along with two representative applications, an augmented reality application and a decentralized workflow orchestrator.
