Data Placement for Multi-Tenant Data Federation on the Cloud [article]

Ji Liu, Lei Mo, Sijia Yang, Jingbo Zhou, Shilei Ji, Haoyi Xiong, Dejing Dou
2021 arXiv   pre-print
The approach consists of a data federation platform named FedCube and a Lyapunov-based data placement algorithm. FedCube enables data processing on the cloud.  ...  We use the data placement algorithm to create a plan in order to partition and store data on the cloud so as to achieve multiple objectives while satisfying the constraints based on a multi-objective cost  ...  When using the cloud services, tenants/users have to pay for them. For instance, when tenants/users directly store their data on the cloud, they would be charged for the cloud storage service.  ...

Towards Secure Cloud Orchestration for Multi-Cloud Deployments

Nicolae Paladi, Antonis Michalas, Hai-Van Dang
2018 Proceedings of the 5th Workshop on CrossCloud Infrastructures & Platforms - CrossCloud'18  
We identify a set of attack scenarios, define security enforcement enablers and propose an architecture for a security-enabled cloud orchestration framework for multi-cloud application deployments.  ...  However, despite the central role of orchestration, the popular orchestration frameworks lack mechanisms to provide security guarantees for cloud operators.  ...  Acknowledgments The research was conducted within the COLA project and received funding from the European Union's Horizon 2020 research and innovation programme under grant No 731574.  ...
