对在线系统（别名云存储服务）中数据存储的安全性和可靠性的担忧导致了独立于应用程序的存储覆盖和控制器的设计，这些存储覆盖和控制器保证了用户需求的安全性和最优性。在漫游和多用户环境中，引导这些控制器的配置和规则应该是容易扩展和可迁移的，以便不简单地将供应商锁定从服务提供商转移到控制器软件或设备。尽管有这一要求，但还没有可用的语言来表达这些规则和政策。因此，我们引入灵活的数据分布策略语言（FlexDDPL）制定存储策略，评估它对语言设计准则，并证明其实际可用性内分散的云存储网关架构。
Concerns about the security and reliability of data storage in online systems, alias cloud storage services, have led to the design of application-independent storage overlays and controllers which guarantee security and optimality with regards to the requirements of their users. In roaming and multi-user environments, the configuration and rules steering these controllers should be easily extensible and migratable in order to not simply shift the vendor lock-in from the service provider to the controller software or appliance. Despite this requirement, there is no language available yet to express such rules and policies. Therefore, we introduce the Flexible Data Distribution Policy Language (FlexDDPL) to formulate storage policies, evaluate it against language design guidelines, and demonstrate its practical usability within a dispersing cloud storage gateway architecture.
