Abstract
Since cloud computing has become more and more important, additional designs should be proposed daily to adapt the systems introduced by it, such as the Internet of Things (IoT). These systems consistsof the physical world (sensors and actuators) and the public networks (the internet).Some solutions must be presented to the cloud computing and multi-tenancy structures. As multi-tenancy increases resource utilization as well as sharing the same database instance to multiple tenants. Multi-tenancy, which permits multiple tenantto share a single application instance. However, merging the multi-tenancy structure with IoT systems becomes more and more challenging due to the different data types of IoT and the multi-tenancy design should adapt to tenants workloads and fit their special requirements.
