Towards scalable on-demand collective data access in IaaS clouds: An adaptive collaborative content exchange proposal

Bogdan Nicolae, Andrzej Kochut, Alexei Karve
2016 Journal of Parallel and Distributed Computing  
We propose a different solution using a hybrid strategy that augments on-demand access with a collaborative scheme in which the VMs leverage similarities between their access pattern in order to anticipate  ...  future read accesses and exchange chunks between themselves in order to reduce contention to the remote repository.  ...  In this work we introduce a novel content exchange and access pattern adaptation strategy that adopts the opposite angle: it pushes only advertisements about the content of datasets accessed in an on-demand  ...

Leveraging Collaborative Content Exchange for On-Demand VM Multi-deployments in IaaS Clouds [chapter]

Bogdan Nicolae, M. Mustafa Rafique
2013 Lecture Notes in Computer Science  
Unlike previous approaches that are biased towards either of the extremes, we propose a scheme that augments on-demand access through a collaborative scheme in which the VMs aim to leverage the similarity  ...  of access pattern in order to anticipate future accesses and exchange chunks between themselves in an attempt to reduce contention to the remote storage where the VM image template is stored.  ...  Acknowledgments The experiments presented in this paper were carried out using the Grid'5000/ALADDIN-G5K experimental testbed, an initiative of the French Ministry of Research through the ACI GRID incentive  ...

Architectural Requirements for Cloud Computing Systems: An Enterprise Cloud Approach

Bhaskar Prasad Rimal, Admela Jukan, Dimitrios Katsaros, Yves Goeleven
2010 Journal of Grid Computing  
Cloud Computing is a model of service delivery and access where dynamically scalable and virtualized resources are provided as a service over the Internet.  ...  The biggest challenge in Cloud Computing is the lack of a de facto standard or single architectural method, which can meet the requirements of an enterprise cloud approach.  ...  Public clouds can access the data on the private cloud with data services. The services in the public cloud communicate with a data service layer.  ...

Moving an application to the cloud

Alexander Gunka, Stepan Seycek, Harald Kühn
2013 Proceedings of the 2013 international workshop on Multi-cloud applications and federated clouds - MultiCloud '13  
Based on on-going work in the context of the MODAClouds EU project, this paper describes an evolutionary, iterative approach to accomplish the migration of an existing application to a cloud based environment  ...  In addition they provide necessary abstractions in order to be less dependent on a specific technology stack or cloud provider.  ...  For the ADOxx business tier this means that an adaptation of the data access layer is required to match the used RDBMS.  ...
