Abstract

Multi-tenancy in cloud computing describes the extent to which resources can be shared while guaranteeing isolation among components (tenants) using these resources. There are three multi-tenancy patterns: shared, tenant-isolated and dedicated component patterns. These patterns have not previously been formally specified. In order to create a precise definition and verify each pattern, we formally specify each pattern using the Z language. To validate the interpretation of our formal description, We empirically evaluate each pattern using the data-tier of a cloud hosted distributed content man- agement application, WordPress, deployed in a Docker container. Experimental results show that the dedicated pattern successfully managed larger numbers of tenants with fewer unhandled request errors. The shared and tenant isolated patterns exhibited larger number of unhandled request errors when the number of tenants increased. We present a selection algorithm to choose suitable multi-tenancy pattern for cloud deployment of content management system.

评估多租户模式在容器化云托管内容管理系统中的效果

云计算中的多租户描述了可以在多大程度上共享资源，同时保证使用这些资源的组件(租户)之间的隔离。有三种多租户模式:共享、租户隔离和专用组件模式。这些模式以前没有正式指定过。为了创建精确的定义并验证每个模式，我们使用Z语言正式指定每个模式。为了验证我们正式描述的解释，我们使用部署在Docker容器中的云托管分布式内容管理应用程序WordPress的数据层对每个模式进行了经验评估。实验结果表明，专用模式成功地管理了大量的租户，而未处理的请求错误较少。当租户数量增加时，共享和租户隔离模式显示出更多的未处理请求错误。提出了一种适合内容管理系统云部署的多租户模式选择算法。
