A simple, adaptable and efficient heterogeneous multi-tenant database architecture for ad hoc cloud

Data management and sharing is the challenge being faced by all the IT majors today. Adds over it, is the challenge faced by the cloud service providers in terms of multi-tenancy of data and its efficient retrieval. It becomes more complex in a heterogeneous computing environment to provide cloud services. A simple, robust, query efficient, scalable and space saving multi-tenant database architecture is proposed along with an ad hoc cloud architecture where organizations can collaborate to create a cloud, that doesnt harm their existence or profitability. An ad hoc cloud fits very well to the scenario where one wants to venture into remote areas for providing education services using a cloud. The results of the proposed multi-tenant database show 20% to 230% improvement for insertion, deletion and updation-queries. The response of the proposed approach is stable as compared to other system which degrades in terms of response time by 384% for increased number of attributes up to 50. The proposed approach is also space efficient by almost 86%. Dynamically changing cloud configurations requires adaptable database and mechanism to persist and manage data and exploit heterogeneous resources. The proposed ad hoc cloud handles heterogeneity of the involved nodes and deals with node specific granularity while decomposing workloads for efficient utilization of resources.
