CSB-UCC: Cloud services brokerage for ubiquitous cloud computing

The Ubiquitous Cloud Computing (UCC) refers to the usage of multiple devices (e.g., smartphones, tablets, etc.) to consume services (e.g., data and application) from multi-cloud sources. To facilitate the deployment of UCC systems, there is the need to build a brokerage platform that aggregates the multi-cloud services that are mostly siloed and divergent. In this work, we discuss our proposed Cloud Services Brokerage for Ubiquitous Cloud Computing (CSB-UCC). The aim of the CSB-UCC is to present a single dimensional view of the services to the consumer who wants to access services from multi-cloud sources. We achieve this by integrating the APIs from different cloud layers such as the IaaS, PaaS, and SaaS. Further, based on the user's security preferences and settings on the brokerage, updates that are published on the cloud sources are automatically pushed to the n-mobile devices of the user without the user explicitly issuing a request. The qualities of the framework are: 1) high scalability in terms of serving higher number of consumer devices, 2) agility to accommodate API-oriented IaaS, SaaS, and PaaS cloud layers, 3) services transparency, and 4) low-latency services synchronization which aims at ensuring application and data consistency across the user's devices.
