Improving provision of a document store as a service in a public cloud

改进公共云中文档存储即服务的提供。该项目旨在开发一个可应用于云托管集群的面向文档的数据库正确性和性能模型。许多现代Web应用程序依赖于托管在商业云提供商虚拟服务器集群上的面向文档的数据库。开发人员做出困难的部署决策，例如如何将联合收割机和复制结合起来以满足服务需求，而没有任何关于精确度的指导。这项研究将使开发人员和数据库管理员能够预测系统在难以直接模拟的条件下的行为。最终，预计这将提高使用文件数据库建立的服务的质量和效率。

Improving provision of a document store as a service in a public cloud. This project aims to develop a model of document-oriented database correctness and performance that can be applied to cloud-hosted clusters. Many modern web applications rely on document-oriented databases hosted on clusters of virtualised servers from commercial cloud providers. Developers make difficult deployment decisions, such as how to combine data sharding and replication to meet service requirements without any guidance on the degree of precision. This research will allow developers and database administrators to predict how systems will behave in conditions difficult to simulate directly. Ultimately, this is expected to improve the quality and efficiency of services built using document databases.
